Date: Thu, 30 Jul 1998 14:36:57 -0500
WBS 1.1.1 Vacuum Equipment(Worden)
1. Gate Valves:
Beam Tube X1 was vented this week to allow GNB and VAT valve
work to proceed. Roughing pumps are being set up at Y2 for
its pumpdown as soon as the VAT valves are adjusted.
Two corner station valves are now in process, one 48 inch
electric and one pneumatic (WGV3,5). Acceptance meeting
for first three valves is Thursday 7/30.
a. WGV11 (Y-end) Passed in-situ leak test.
b. WGV12 (Y-mid BT) Passed in-situ leak test.
c. WGV17 (Y-end BT) Passed in-situ leak test.
d. WGV14 (X-mid) Complete except for in-situ leak test.
e. WGV18 (Y-mid) Complete except for in-situ leak test.
f. WGV20 (X-end) Waiting for new gate.
g. WGV16 (X-mid BT) Waiting for new gate.
h. WGV15 (X-mid) Bellows leak testing underway(new bellows installed).
i. WGV19 (X-end BT) Waiting for a new lead screw.
j. WGV3 (LVEA-48) Bellows ok, lead screw ok, gate ok, bearing unit
needed tightening. Limits will be adjusted next prior to cycling.
k. WGV5 (LVEA-44) Needs new bellows. Preliminary look suggests
that gate is ok(will be measured later).
l. WGV10 (Y-mid) Waiting for bellows.
2. The 100 hour, post vent/purge, pumpdown is underway in the
LVEA. This will be the last vacuum test in the LVEA. Two truck loads
of bake blankets have gone out this week to LA. Only those blankets
required for the right end station bake and a valve test have
been
kept on site. PSI will soon be ready for their first bake in LA.
3. Installation activities:(No report-Kyle is deep into the bake oven....
and Washington installation activities are substantially complete.)
4. Livingston Vacuum Installation (Cecil Franklin)
Left End Station "Y" Arm:
(1) PSI labor force begin moving equipment and tools to the End Station
to
support the installation and alignment of the Vacuum Equipment.
(2) PSI and LIGO personal completed the installation and helium leak
testing
of the annulus piping for the 48" B/T valve.
Left Arm Mid-Station:
(1) PSI and LIGO personal completed the installation and helium leak
testing
of the annulus piping for the 48" B/T valve.
(2) On 7-28-98 the 48" B/T valve was open and locked in the open position
to
allow CBI to start the "Y" Arm Pump-Down.
Corner Station:
(1) PSI and LIGO personal completed the installation and helium leak
testing
of the annulus piping for the 48" B/T valve.
(2) PSI continue to Grout all installed Vacuum Equipment and Valves
Support.
Right Arm End Station:
(1) The 14,000 gal. Liquid Nitrogen Storage tank was cooled down and
filled
by the BOC customer Service Group without any problem on 7-29-98.
WBS 1.1.2 Beam Tube (Jones)
a. Livingston Installation
CBI has performed an accumulation on the X arm modules
(simultaneously) on the evening of 7/23, and followed with a
simultaneous instrumented global calibration on the evening
of 7/28. Analysis of the first accumulation results is
encouraging; applying the global calibration results is in
progress. CBI expects to repeat the global calibration on
the evening of 7/30, with the intentional air leak on the
second module. If the data is deemed acceptacle by Weiss,
acceptance activity will move to the Y arm. Currently, the
roughing pumps and Type B pump port hardware have been
installed on the Y arm and leak checked. PSI has opened the
midstation valve in preparation for pumping.
CBI's data acquisition system is still not fixed. Temperature
and pressure data to support the acceptance testing has been
taken manually by personnel working around the clock.
CBI plans to survey peak closing torque measurements on all
VAT pump port valves.
The transparent PVC caps for the GPS enclosure penetrations
have been received and will be installed shortly. All of the
GPS shots on the control supports for X1, X2, and Y1 modules
have now been post processed with precise ephemeris, with
acceptable results. Reshoots of three control supports on the
Y2 module remain, as well as post processing. Once CBI
releases modules as being final aligned, we will task the
John E. Chance company to perform QC checks. discussions
with them on methods are continuing.
> 1.1.3 & 1.1.4 BTE and Civil Construction (Fred Asiri)
>
> >>Issues:
> Hanford:
> 1. Water System Integration: We have received the NSF approval for
the Apollo Subcontract for the Hanford Water System Integration.
2. New Staging and Storage Building. Design and specification are
being revised by the Architect to bring the estimated
cost within
the budget.
3. The asbuilt drawings for the Hanford site has been completed . DCC
Has completed the asigning of proper LIGO number to the
asbuilt
drawings. Copies of asbuilt drawings will be made and
will be
distributed shortly.
> Livingston:
1. The asbuilt drawing is being prepared by Parsons. The marked-up
drawings have been received from the subcontractors.
I will be at the Hanford site next week to coordinate and
participate
in the SEI Installation effort.
Hanforf Construction (Otto Matherny)
Levernier
Levernier submitted a plan of action
where the 17 outstanding
items will all be completed by the end
of July 98. Sixteen of
the 17 are already complete.
The largest of the outstanding items
is the completion of
the opposite season testing of the HVAC
system and training.
OTHER ITEMS
The water system modification contract
will start at the site
on August 13, 1998.
The new building had to be completely
redesigned to fit
the budget.
There was a selection of the mechanical
maintenance contract.
Notification is pending on project approval.
Livingston Construction (Gerry Stapfer)
Most of the leaks appear to have been fixed now. Some water still enters
near the enclosure penetrations and we are investigating if the leak
is in
the enclosure or part of the building.
All of the cooling coils have been installed correctly at the end and
corner
stations. There is not a drop of water in the air handlers during
this very
humid and hot weather thus the problem appears to be corrected.
Landis and Staefa have started the water integration re-work and estimate
the task to be completed within two weeks.
Yesterday we found that the fire water system is defective. Two large
8 inch
check valves are leaking. This prevents the booster pump from reaching
the
static pressure. Bernhard Mechanical has been informed and has promised
to
look into the problem. We also found that Bernhard had installed the
back
flow preventer valve backwards in end station -1. The HVAC make-up
water was
therefore not working and the HVAC shut down for lack of water pressure.
Bernhard is fixing this as well.
DEMCO has almost completed the LIGO substation along Hwy 63. They have
installed a separate 13.2 KV line from the substation to arm-1. We
expect to
be on this new distribution by the end of next week and anticipate
that this
will be the end of our air-conditioning problems.
The State of Louisiana is scheduling to start working on the LIGO access
road next week. Once they get started LIGO will use the by-pass road
on to
arm-1 as our entry. We anticipate that when that becomes effective,
Costal
Bridge Co will have completed the paving of the arm-1 service road.

-----------------------------------------------
40m (Jennifer Logan)
--------------------
This week we have made progress characterising the older suspensions
and
are looking at how their resonances couple through to the interferometer
signal. In particular we are finding that the local damping on
most
of the suspensions has been set too high and so we are re-establishing
the correct servo settings. On a slightly more discouraging front,
the
input light to the interferometer has fallen by ~ 40% in the past
couple of weeks. We are starting to sort through our hoarde of
pockels cells to ensure that we are ready to replace the in-vacuum
cell
should this become necessary.

--------------------------------------------
Prestabilized Laser -- Peter King
--------------------------------------------
- For most of the current reporting period the PSL Lab has been hampered
by
the lack of a network connection. The network connection is needed
to run
the EPICS interface. Late yesterday (07/29/98) the network connection
was
restored.
- R. Abbott has completed the 35.5 MHz frequency reference card for
the
pre-modecleaner (PMC) servo. The cards for the PMC servo have
been
received and are currently being stuffed with components.
- Various electronics components for deployment at the LIGO sites have
been
ordered by R. Abbott. These include things such as power supplies,
miscellaneous rack components etc.
- Some small vacuum compatible modifications have been made to the design
of the vibration isolation stack used with the PSL reference cavity.
The
main difference being the addition of a number of vent holes to remove
virtual leaks.
- Ion pumps used to keep the reference cavity vacuum chamber have been
ordered. The ion pump chosen is manufactured by Physical Electronics,
who
used to manufacture the ion pumps for Perkin-Elmer and has a pumping
speed
of 20 liters per second. This size pump was recommended by various
firms
as the smallest pump to consider given the 8 liter volume that needs
to be
evacuated.
Input/Output Optics -- Dave Reitze, UF
-----------------------------------------
IOO - Dave Reitze
Hanford planning -
The UF group has planned the deployment of UF personnel at Hanford.
A
detailed schedule will appear in next week's weekly report.
Mode Matching Measurement -
No report received.
Machining -
We discovered that the PSL periscopes, by virtue of their size, cannot
be
effectely welded. The periscope parts act as giant heat sinks which
prevents the weld from getting hot enough to take. The result
is, of
course, a cold weld.
We are looking at alternatives, including bolting the periscope together.
Procurement -
The first batch of IOO in-vacuum REO coated optics will be ready and
sent to Hanford late next week or early the week of Aug. 10.
High Power Testing -
Sany has completed the wavefront testing of the off-the-shelf optical
flats for the optical feedthroughs. No serious problems were
found.
Core Optics Procurement and Metrology -- GariLynn Billingsley
-------------------------------------------------------------
Final acceptance testing of the IR interferometer is taking place at
Caltech this week.
GO reports that the final ETM's (#7,8) polishing is completed.
CSIRO has finished the 4th 2kITM, which will be sent to REO for coating
along with the other 3 ITM's about 2 weeks from now.
Core Optics Coatings -- Helena Armandula
--------------------------------------------------
REO Contract - COC Coatings: Two coated beamsplitters shipped from REO
last
Tuesday and the other two will ship on Friday. As soon as the parts
are
received we'll measure the witness samples to confirm that the specs.
have
been achieved. REO is waiting to receive the fourth 2ITM to start coating
those parts. Next week they are going to schedule our test pieces for
coating, as well as the UFL's substrates.
COC cleaning: Achieved good results when cleaning a coated pathfinder
optic.
This exercise tested the handling fixture as well as proved the cleaning
process.
Indium bonding: Procured a push tester and an Arbor press to start
evaluating indium bonding. Fixtures are being designed for indium bonding
the dumbell-magnet assembly onto the mirror.
Core Optics Support -- Michael Smith
------------------------------------
ETM PO BEAM:
M. Smith has completed an analysis of the optical properties, location,
and
spot size of the ETM PO beam relay lens which will mount on the ISC
ETM
end-station and mid-station optical tables. The description of the
lens and
a conceptual mounting drawing, together with the analysis data will
be sent
to ISC; who has agreed to take responsibility for the relay lens.
ISC TELESCOPE:
A data package is being gathered describing : 1) lens specification,
2)
focussing parameters, 3) ACAD mounting sketch; to be sent to ISC who
has
agreed to take responsibility for the ISC telescope.
PO TELESCOPE
Three full-size wooden mockups of the PO telescopes have been build
and are
positioned in a simulated HAM 10 configuration to check the layout
compatability. The mockups have also provided feedback on some features
of
the height and tilt adjustment mechanism which will be redesigned.
BEAM-DUMPS:
The shop is building a prototype of the double beam-dump and mounting
structure, as used in BSC 7 and 8; completion is estimated in two weeks.
A.
Bagdalian is continuing the ACAD placement of beam-dumps in BSC 7.
ITM BAFFLE:
A. Rosa and M. Smith have completed a preliminary top-level design
layout
of the combination ITM baffle/beam-dump, which will be placed in the
spools
WBE5 and WBE6. The baffle incorporates access holes for the ISC optical
lever beams which reflect from the 2K ITM and 4K ITM mirrors. A. Rosa
is
proceeding with the detailed component design.
TEST EQUIPMENT:
IR AUTOCOLLIMATOR
IR LED's have been received for evaluation as a possible illumination
source for the IR autocollimator. The work will continue when J. Kern
gets
back from Livingston next week.
STEERING MIRROR MOUNT TEST:
J. Kern and M. Smith are still testing short-term repeatability and
long-term stability of various commercial mirror mount candidates for
the
PO steering mirrors.
PERSONNEL DOWNSIZING:
D. Rose has requested his work load be reduced to half-time effective
7/22/98. K. Mailand will be permanently leaving LIGO effective 7/30/98,
due
to personal reasons. Ken will be available for limited consultation
during
the next two months. The remaining COS detailed component design tasks
will
be completed using available in-house designers and by outsourcing
entire
assemblies wherever appropriate.

Seismic Design (Mike Fine)
--------------------------------------------------------------------
1. Coiled Spring Testing:
Hytec has tested 25 epoxy-less springs. The loss factors of these springs
are slightly lower (~10%) than those of the epoxy-bonded ones. More
epoxy-less springs (22) are expected to arrive at Hytec next week.
In
the mean time Hytec will select 5 springs for more extensive
tests--evaluating
the lateral and axial spring rate and damping prior to and after 1000
compression cycles; 3 springs will be shipped to CIT for creak test.
2. Fasteners:
Testing of the coated fasteners (3/8-24 thread size) is completed.
Hytec is
in the process of documenting the results. The short story is
that all the
coated fasteners that were of the class 2 variety performed well and
the
class 3 fasteners not as well. In holes where the parts are well machined
Hytec has experience little or no problem. Allied Engineering has had
a very
difficult time manufacturing the tapped holes in the SST. This
is due
primarily
to the lack of lubricants typically used when manufacturing.
The result is a
hole that barely passes prior to the final bake cycle. The final
bake has
caused some apparent relaxation in the material that further reduces
the
holes
clearance. There are a number of things that we can do, such as going
to a
slightly oversize tap, etc using only class 2 bolts, etc. This
issue should
be finalized in a couple of weeks.

Detector Systems Engineering -- D. Shoemaker/D Coyne
(WBS 1.2.1.1.9)
---------------------------------------------------------
Global Diagnostics System
(Rolf Bork, David Shoemaker, Daniel Sigg)
--------------------------------------------------------------------
Received some of the VME GPS boards and wrote a hardware driver.
They are used by GDS to obtain the current time and to install a
heartbeat clock which interrupts the CPU at 16Hz (synchronized
with the GPS 1pps). If one wants to avoid using external hardware
the heartbeat clock has to be derived from one of the internal
clocks at 100Hz or 3MHz. Since the first one is not a multiple of
16Hz one has to divide the 3MHz clock. However, the highest
possible division rate is only 65535. Hence, we decided to run the
interrupt rate at 64Hz, and neglect 3 out of 4 in software.
An other chapter has been added to the ever amazing make file
technology. It is now possible to compile/link for multiple target
platforms and CPUs starting with the same source file tree. And,
the problems with 64 bit integers on VxWorks/Baja have finally
been put to rest.
Physics Environment Monitor (Alex Marin)
-------------------------------------------
No report.
Optical Contamination (Daqun Li)
--------------------------------
Ringdown and mode spacing (absorption) data of vac-seal have been
continuously taken for a week without significant change in both
data. This process will carry on for a few weeks before the
Vacuum Review Board meets next time to decide the fate of vac-seal.
Measured the reflectivity of REO final beam splitter coating shot
(with AR coating on back surface) to be 50.3% +/- 0.5 % for
p-polarization at 45 +/- 0.5 degrees with a 1064 nm laser.
Working on electronics of the scatterometer, which will be
eventually incorporated into the Core Optics Loss Scanner to
detect inclusions of core optics.

This is an important week for the effort to review and correct a significant proportion of the LIGO costs and commitments. The audit team is attempting to get correcting entries as required into the system for the close of the books for July for most of the contracts that we have identified for their attention. We should be able to see the results at the end of next week. I am optimistic that considerable progress has been made. However, some fundamental questions remain.
This will probably be the last full week for Darryl Lim, the KPMG consultant. Darryl will be on call starting next week.
The following contracts have been reviewed or are in process. We estimate that the corrections listed will relieve approximately $15.8 million in excess open commitments. Also there are several hundreds of thousands in excess actual costs that will be removed, primarily extra amounts retained instead of paid from retainage or excess overhead charged.
Submitted a request to the General Services Administration for the necessary documentation GSA form 3525 to establish a GSA coustomer Supply Center (CSC) account for each Observatory.
Assisted the Livingston Manager with the shipping of thirty-nine(39) cartons of equipment, books and office files. ( Acct # 5N501)
Assisted the Optic Engineer with the two boxes to Research Electro Optic (attn: Mr. Dale Ness) containing small optics no serial numbers, dollar value of $3000.00 and a Pathfinder transit case containing Pathfinder Optic SN # COC-A008 dollar value $ 35000.00. Acct# 5F514
Provided the LIGO Livingston Observatory with two(2) Forklifts
thru Government Surplus via NASA activity the arrival dat at Livingston

__Reliability: No report
__Integrated Layout/Drawings: Nothing to report
__Mock-ups:
ELECTRONIC RACK LOCATIONS
The layout of the placement of Electronics racks
was issued under an
engineering or preliminary release. Final locations
are being verified and
should be incorporated for an "A" release under a DCN, next week.
ELEVATED PLATFORM FOR MOCK UPS
This project is just now being started after many
delays. The plan is to
layout a platform which wraps around the seismic
actuation components and
for stability, attaches either to the floor or the access nozzle flange.
Some investigation is required before a decision can be
made. First unit
will probably be evaluated in Hanford. Anticipate ordering a first
evaluation model in mid August.
1.4.3.3 Modeling & Data Analysis (KB/HY/AL)
Hiro:
SUS/SEI implementation in e2e :
GianCarlo Cella arrived on July 27. We have a meeting every morning
about
the modeling of the mechanical strcuture, Cella, Mohanty, Biplab, Hiro
and
Ed.
The dicsussion are focused on the three goals we would like to achive
during Cella is here, until August 10.
(1) Fundamental dynamics
(2) Syntax describing the mechanical structure
(3) Program structure
Major items discussed so far are :
Mohanty summaried his work and discussed what are do be further studied.
Cella explained the syntax he used for VIRGO stack. Ed reviewed the
syntax
and commented that it will be easy to expand alfi to be the GUI for
the
constrcution of the mechanical structure.
The class strcuture of the mahanical elements are also discussed.
Single Mode Optics of Adlib :
The validation process of Adlib opitcs showed some discrepancy between
twiddle. It turned out that the major partner (Inphase or Quadphase
demodulated) of the error signal was OK, but the minor partner was
wrong.
From various aspects, this discrepancy is studied.
Modal Model implementation :
Keep going, but not major progress. [AL note:
LSC FDR raised certain needs by Detector for
near-term support for Ware on MM modeling for
acquisition/lock. Lazz to set up a meeting
ASAP]
ALI : - visualization front of e2e under development by Ed
Handle symbolic column name translations.
Worked on getting multiple equations displayed.
Other MEETINGS:
Ed attended the Friday morning LDAS Group meeting on DBMS evaluations for LIGO.

Phil Ehrens:
This week:
* I attempted to configure my computer and install some
programming tools. Many system "man" pages were missing
and system header files on SIRIUS are in a bad state.
I can compile on MUSCIDA, but this involves much juggling
of directories and wasted time. To compile using MUSCIDAS
tools, I first have to copy to SIRIUS, which has NO DISK
SPACE available!
* Overcame a bug/feature in the Tcl socket support which
makes eof difficult (impossible?) to catch. Wrote a
generic procedure which attaches a Tcl comment line to
all outgoing files from the server. This can then be
parsed as eof. After this little problem was solved
I cleaned up the rudimentary client/server model of
the LDAS interface and began work on the data visualization
functions. I am prototyping with a 100k datafile.
* Fonts which were available yesterday have up and flown
today, causing 3 hours anxiously wasted time...
Dave Farnham:
Repartitioned and Reinstalled Windows 98 on m27.
Repartitioned and Reinstalled Windows 98 on m27 again. Due to
the
limitations present in the RedHat Disk Druid partition program, the
Linux
partitions had to come first.
Installed RedHat Linux on m27.
Installed current upgrades from www.redhat.com/errata.
Configured and rebuilt the kernel.
m27 is now pretty much configured and setup. I have written out
instructions regarding the installation process (which took much longer
than the few lines above might indicate) which I have emailed to you.
All upgrades and installed packages have been burned onto a cdrom so
they
don't waste hard drive space and so they are easily available.
I have also contacted PowerQuest who have told me that the current
version
of PartitionMagic will not support our 10 GB drives, so we must wait
until
version 4.0.
Furthermore, ObjectSpace is no longer supporting Linux or the Gnu
compiler. So, I have installed the solaris version of the ObjectSpace
package on m27 and I am attempting to modify the code to get it to
work
on
our Intel Linux with the egcs compiler. All changes are being
recorded
via cvs. So far, I have been able to modify the package so that
it
compiles on m27 without errors. I am now attempting to compile
the
example code and use it to ensure that the package is operating
correctly.
That's about it. If the examples work I'll try out the modified package
on Sadan.
Kent Blackburn:
KB spent much of the week configuring workstations and networks. Several
new
hubs for extending the port count on the eithernet switch on the 6th
floor were tested.
None of these supported both 10 Mbit and 100Mbit operations at the
same
time. This
is a real problem, especially with the 10Mbit printer up here taking
up
a 4 MAC 100 Mbit
port on the switch in the server room. KB also had to reinstall drivers
under Windows95
from a network dropout that was unexpected and reinstall OpenStep.
Substantial data
was lost under OpenStep but both the Windows95 and the OpenStep CPUs
are
back
on line.
KB called ObjectSpace this week to request the new version of the
ObjectSpace C++
class library that was promised as part of our purchase in June.
ObjectSpace provided
an account and password for downloading the software over the web.
Dave
is now
working with this new code (see his report above). However, ObjectSpace
has dropped
several lines of compilers and Operating Systems from there support.
This is unfortunate
since the lines dropped were targeted by LDAS. Dave is looking to port
the code to these
and has made progress already in doing so using the ObjectSpace code
as
a starting
point.
KB met with Dave and Phil several times this week to discuss progress
being made on
issues of the sockets and the TCL/TK environment. Phil has developed
an
interesting
server / client in which the client requests its code in the form of
TCL
at the time the
client is started. This will be a very powerful and flexible paradigm
for user software
which runs as a client that gets custom configuration from the server
in
response to
user inputs. The server / client model was tested by Kent and Phil
under
Linux and
Windows 98 (where Kent had installed TCL/TK) and found not to work
as
advertised
on the Suns. Phil tracked down the problem and the code was able to
run
between Suns,
Linux workstations and Windows 98.
Tilav:
I ftp'ed the 64 bit format Time Conversion library to Hanford for
Daniel to try it out on the VXWORKS operating system. He quickly
realized that the library was not VXWORKS compatible.
As a quick solution we will try a striped-down version of the library.
I will supply only couple of routines which do the time conversion
from the GPS board to GPS seconds. The whole library may never be needed
as a front-end application. The problematic parts are mostly related
to
GPS to UTC conversion.
Majid:
I have been debugging the Fcl library and fixed all the memory leaks
found. I have now ran some tests for periods of two hours or
so, with no
increase in memory size.
Also continued bringing the package up to spec by implementing IO for
two
more classes, SimData and ProcData. Three more classes need to
be
implemented similarly.
Continued to improve the Fcl web page. The Doc++ documentation
was fixed
after a file reorganization. More comments were added.
There is now a
HowTo's section, which will be continually build on. I have also
started
to include some utility tools for the package.
I have also spent some time working on the Algorithm class definitions
and
have thought about implementing some basic signal processing algorithms
with my SURF student. I will try to interface the algorithm class
library
(Acl) with ROOT sometime next week.
Lazzarini:
DOE WFO for the ESnet access MOU has been completed and has been forwarded
to DOE
field
office HQ in Oakland, CA for sign-off and forwarding to NSF/Caltech.
Drafted a preliminary spec. for metadata , event data, and reduced data
sets for LIGO.
Draft distrbiuted via www to interested parties fro review.
Spent a lot of time tying up lose ends from Millikan move&rehabilitation of 6th floor.
Met with R. Williams and B. Sears to discuss metadata and wwww access
to data. They have
developed a specification for how such data can be represented. This
is being ioncorporated
into my draft spec. doc.
I started dialog with CDS and with LDAS
people regarding electronic logging of data from operations. the links
provided by Coles in
his trip report for the WOA CONFERENCE have proved helpful. E-log from
FNAL is a Perl
application whose development appears mature. We have requested the
code to see whether it
might work for LIGO.
COLLABORATIVE RESEARCH (LS Finn, Mohanty, Mukherjee, Romano)
Mohanty:
I have been working on finishing up the calculations for the LIGO suspension
for end mirrors. I have assumed a simple model in which the single
wire loop
is replaced by two wires attached at the sides of the mirror. For the
time
being, the wires are assumed to be viscously damped but each wire has
two
transverse polarizations and one longitudinal mode. G. Cella wil help
with
transforming the transfer functions involving transcendental functions
into digital filters. He may also take a look at the optimum way to
invert
a certain matrix that is required in the SEI/SUS modelling formalism.
Misc.: Shifted to Millikan 6th floor. My paper on the project that
I did
in collaboration with David Blair's group at UWA has been accepted
for
publication in MNRAS. Some minor modifications in the TeX file are
needed.
MUKHEVJEE:
The problem related to start up transients is taken care of in case
of the
fir filters. Right now I am running simulations to obtain the best
value of
Rk - the variance of the measurement noise. Rk, after inclusion of
filtering
in the state space equation, should ideally be zero. This however,
introduces
computational errors. The purpose of the simulations that I am running
now
is to study how Rk values affect the filtering process.
P.S. (1) I moved office to Millikan 6th floor on July 27.
(2) I shall be undergoing a surgery on Aug.
3. I have been advised to
remain at rest for a week. Hence I shall be
away from office during
Aug. 3 - 7.
1.4.4.2 General Computing (LW/TE)
MIT:
1. Wrapping up the move to their new location.
2. Printers and modems are back on-line.
3. Starting to upgrade machines to the latest version of Solaris 2.6.
Livingston:
Nothing to report
Hanford:
1. Placed several orders for software, followed up on order for
tape
robot (now scheduled to arrive Aug 7), talked with Artecon many times
about ArteSTAK back-up software (it may not work with Solaris 2.6),
reviewing Solstice back-up as an alternative, and followed-up with
Sun
on the order for the E3000 service contract.
2. Opened several new user accounts, connected several more wall
jack
ports to the LAN, and I'm moving computers and components around to
create two reliable, usable laptops for staff members who will be
traveling alot or working from home next month.
CIT:
1. Fixed a Gateway box which required a full reinstall of the
OS and drivers
from scratch. Since the new installation there have been no reported
problems.
Currently, waiting for a response from Micron to get the PC from them
fixed.
2. Samantha finished setting up the Gateway Laptop and is doing some
final
testing.
3. While working on an NT station to install all of the necessary software,
Samantha found that it would not install First Aid97 and excell. It
was also
necessary to reload Service Pack 3 to eliminate some other problems
on the NT
machine.
4. Worked on cleaning up power cables and installing network cables
at Millikan.
Still working on getting everything configured correctly and updating
some of
the machine names and addresses.
5. Resolved various e-mail problems with the Eudora product. IMAP appears
to be
a cause of some problems so the people were switched back to POP service
until
we get time to look into the IMAP problem. It is recommended that Eudora
lite be
used on the older PC's, it appears to work better than the fully loaded
version.
6. Various hardware components were replaced on PC's and SUN workstations.
7. Samantha is working on sending the old trade-in units to SUN.
8. Finally, the connection to Lauritsen is back on-line.
9. (Barbara K.)Finished setting up new home, intermediate, and lower
level pages
for the new web site. Now am testing all the links and doing
some tweaking.
Next will move the site to the public.html directory on ligo server
so
page-owners and other interested parties can review the site before
it goes
public.
10. Met with Sanders, Turner, Lindquist, and Wallace about setting up
the NT
server and WebBase so DCC data will be available via the web. This
project
has high priority. Applications have already been written to 1) search
for
all documents and view PDF versions and 2) reserve a document number.
Once
the web service is working, the DCC database will be moved to the NT
machine. Purchased 2 NT server books.
11. Barbara is checking into site licenses for Oracle and Objectivity.
LIGO's
Oracle licenses expired in May 1997. According to ITS, Caltech
does not have a
site license for Objectivity. Barbara is checking with the folks at
AIS about a
site license for Oracle.
12. (Barbara K)Helped with problems with the DCC application.
First the gsparc
drive that stores the DCC database was temporarily "lost". Then
the application
on Linda's PC was clobbered and had to be reloaded. System software
on
Linda's PC also seems to be having problems and is going to be reloaded.
Worked with PMA division and Gary on the ASI.
The move to Millikan Library is essentially complete. This week I have been working with PMA and Albert to get the loose ends wrapped up---transferring voicemail, making arrangements for the purchase of two overhead projectors, and preparing the LIGO visitor cards for access to the Sixth Floor among other things. The Visitor cards for the sixth floor have the graphic of the gravity wave on them.
Worked with the phone office to transfer phones and get new extensions for the abandoned offices on the third floor of Bridge as well as moving Mark Coles's line and Ed Jasnow's line.
The checklist committee has come up with (we hope) a finalized version of the incoming/ terminated LIGO employee checklist. We are beginning in earnest to write up the LIGO policies and procedures manual.
I am taking requests for space now that we have had the third floor of Bridge open up. Some of them are actually quite reasonable requests.
Irene Baldon
Arranged and processed the paper work for 13 trips to various locations, including 1 trip to Europe.
Worked on the ever present backlog of Expense Reports. New trips slowed and I able to complete a significant number of reports.
Performed miscellaneous duties as requested by various members of the LIGO Project here at Caltech, as well as for members of the staffs of each of the two (2) sites.
Prepared and distributed the Weekly Travel/Vacation Itinerary Report for LIGO Staff and Visitors.
Processed Hourly Payroll, incorporating various recent changes, new hires, terminations and the processing of Vacation/Sick Leave accounting.
Rita Torres
For I. Petrac did Addendum No. 1 to RFQ IP-301 for Cable Tray Fab. & Install. at Hanford. Also called bidders to remind them of job walk scheduled for Thursday, 30 July. Did change order No. 2 to NYMA, change order No. 2 to Corning, Inc.
For E. Jasnow verified vendor addresses for EJ-298, the Hanford Building. FedExed the Cancel Solicitation letter to each vendor and distributed internally. Made copies of contract then FedExed executed copy to BOC Gases.
For W. Tyler did more updates to notes from June meetings at LHO on laser safety issues. Distributed to all actionees.
For P. Lindquist distributed CCB minutes of 7/16/98. Edits to forms for Advanced R&D program.
For S. Whitcomb obtained vugraphs and copies for material for ASC final design review of 7/23/98. For D. Shoemaker did print outs, copies and distribution for material to be covered at LSC final design review of 7/29/98.
Helped with travel POs for I. Baldon. With the help of B. Kratochwill explored updating the roster in html.
Dorothy Lloyd
Entered AP30 reports into the database. Continued processing the constantly growing requests for PR's. Processed POs, Change Orders, Check Request, etc. as well as an extremely heavy load of invoices.
Followed up and tracked many problems with invoice payments.
Continued to monitor and support the temp. Provided clerical support
were needed.

=========================================================
LIGO Hanford Observatory (LHO) Operations (F. Raab)
=========================================================
General Items:
--------------
Our focus continues to shift toward getting the beam-tube bakeout
and interferometer installation into high gear. Performance testing
of the HAM stack is ongoing, VAT is repairing beam-tube valves and
Lee Cardenas is preparing the staging for the real HAM-SEI assembly.
Contractors have sized up the cable-tray installation job and are
sharpening pencils for the bid. We are reworking the package for the
additional staging building. We just installed a beefier phone
system to support installation activities, moved in more furniture
to accomodate visitors and we are preparing plans to add to our
general computing system. Our REU students visited Caltech this
week and are now back, entering the home stretch on their projects.
Bake Oven:
----------
(K. Ryan)
As of 7-30-98 we (Betsy and I) have performed three "heatings" of
the Bake Oven. These were devised to confirm our understanding
of
the heater controller more than to get any meaningful data.
Beginning Monday 8-3-98 we will begin a 72 hour 25C-125C ramp+soak
profile which is meant to better simulate a "real" bake cycle.
We had some problems earlier this week with blowing variac fuses due
to inrush. This problem went away once we got the correct fuse
type
(time delay/motor). We have also installed a "panic button" to the
control panel in series with the over temperature protection. This
provides a means for laymen to shut down the baking should a problem
(obvious over heating) be noticed by passersby.
I will use the time during the 72 hour bake to begin drafting
procedures related to the Bake Oven. I also plan to begin eliminating
the outstanding "punch list" items.
HAM 1st-Article Test:
---------------------
(C. Gray, H. Radkins)
Last week we lowered the Optics Table/Leg Elements onto springs.
While lowering this system we noticed a rotational motion as the
springs were being loaded. This along with a possible "off
centered-ness" in lowering of the Optics Table/Leg Element system led
to a yaw angle of 8 mrad. (GHS note: A very important
observation that is
an early payoff of the first article exercise.
We can now work out a way to
remove this rotation prior to production.)
Mark Barton, Alex Marin, Warren Johnson, and Joe Giaime began
performance testing. A drift test was first taken and has been on
going from late Thursday nite. Dynamic Tests are set to begin today
(7/30).
Continued Staging of actual HAM installation work with Lee Cardenas.
Optics & Lasers:
----------------
(D. Cook)
We have the DI water system installed and plumbed to the Vacuum Bake
area, and to two locations in the Optics Lab. The new transverse flow
benches for the Cleaning Station in the Optics Lab should be delivered
tomorrow along with a cleanroom garment rack. The new larger laser
safety curtain is installed. The rest of the laser safety barriers
are due in next week.
Particle counts in the LVEA showed significant improvements as PSI
has removed the majority of the bake-out blankets from the building.
Clean up of the LVEA has not been done as yet. We have started using
a cleanroom garment laundry service to supply our needs. Should prove
cost effective over using disposables as well as hassle free in
regards to maintaining inventories.
LVEA and Optics Lab laser safety issues are still on going.
Electrical/Electronic Systems:
------------------------------
(R. McCarthy)
Installed Battery Charger for Warehouse forklift. Issued work order
to
Sun River for installation of receiving area charger.
Worked with US West on the installation of new PBX. We now are capable
of installing 200 phone lines. We now have ability to put phones in
labs and LVEA. After cable tray installation will have phones in the
VEA's.
PSL Laser Table enclosures have now been rewired and powered up.
Required Sun River to make some corrections to wiring as received
from vendor.
Finally replaced faulty exit lights in Mid and End stations only to
find others with problems. Will be working with vendor and Valley
Electric for permanent fix.
Conducted walk through for contractor on Cable Tray RFQ. Thanks
to
Irena Petrac and Bill Baldwin for a great job.
Computing Systems:
------------------
(C. Patton)
A first draft of the General Computing Conceptual Design document has
gone to Fred for review, I will also be asking Daniel Sigg and Larry
Wallace for comments. I am also working on a General Computing
User's
Guide for LHO visitors and staff. The Guide will outline what
computing services are available at LHO and what System Administrator
services are available.
The MATLAB software should be here today. The Tape robot is now
scheduled to arrive on Aug. 7, the vendor didn't have a reason for
the
delay. The AretSTAK back-up software to go with the tape robot,
may
not work with the latest version of Solaris operating system.
I've
been talking to the vendor and to Larry Wallace to figure out if
ArteSTAK is going to work for us. I've also been reviewing Solstice
back-up software to see if it would work better for us.
The LHO general purpose laptop doesn't work reliably, and never has.
I
am moving computers around to free up another laptop which does work,
and have been upgrading a laptop passed on to General Computing from
the HVAC control system. Once these laptops are available for
use, I
will send the broken one to the dealer and try to get it fixed, again.
We have had quite a few visitors this past week, so I have also been
opening new user accounts, connecting more wall jack ports to the LAN,
assigning temporary IP addresses, and answering many questions.
This
is helping me to know what kind of information I need to include in
the General Computing User's Guide.
Beam-Tube Bake Out:
-------------------
(M. Lubinski, M. Guenther, K. Stiff and W. Althouse)
Electrical Support Services Contract:
Report from Sun River
Accomplishments:
Two connexes were loaded onto the 40ft flatbed trailers and welded
down. The heat exchangers, 45KVA transformers and 500KVA transformers
were loaded and bolted to the trailers. The connexes contained
DC
Power Supplies, B-2 panel, Metering panels, Shunt Cabinet, and
lighting.
Problems/Concerns:
No problems or concerns encountered this week.
Mski note: Sun River has delivered one of the flatbed trailers,
and
the second will be delivered this week. Sun River is currently
completing assembly of the 45 KVA transformer and power panel setups.
When the second DC power supply is here and the 45's are on station
Sun River will bring PUD out to hook them up.
Cryopumps:
The Cryopump at port Y2-3 was run for 4 days to verify performance and
to
log data on the pump. The pump maintained temp and the test run
was
successful.
Beam tube port valves(10" VAT)
Late report input: VAT representatives arrived on Wed 7/29 to adjust
the 10" valve mechanisms. By Thursday morning, adjustment was
completed on all the valves needing attention on the Y2 beam tube
module. VAT will return at some future date to perform these
adjustments as needed on modules Y1, X1 and X2.
Data Acquisition and Temperature Control System:
Report from Mark Guenther:
A total of 133 thermocouples have been connected and are logging. The
bulk of the remaining thermocouples to be connected will be used to
track heater blanket temperatures. Cryopump signal calibration
was
checked during a test run of a pump on port 3. DC power supply
current shunt connections were checked, and calibration signals sent
to the computer for logging. An output module located inside
a
connex box was discovered faulty and replaced; this is most likely
related to our recent high temperature weather. Possible fixes are
being investigated.
