The Project Control Meeting
Agenda for Monday August 9, 1999 will be:
(Meeting time: 10:30 am Pacific Time)
Indeed, the search engine is now on the
public website for open use in querying all technical, engineering
and physics publication documents. Thus it can now be accessed from anywhere
on the Web. - GHS
Bake Oven:
----------
(K. Ryan)
LHO Vacuum Bake Oven A load #48 consisting of Beam Dump Support Tubes
and
misc. ETM and Beam Dump hardware was released on 8-3-99.
Load #49 consisting of large optic BS01-B, three primary APS telescopes
and three secondary APS telescope mirrors is in process and should
be
released tomorrow 8-6-99.
Load #50 looks to consist of four LOS structures plus misc. COS hardware
and should begin it's vacuum bake tomorrow 8-6-99.
While I think that we are doing a great job
of actually processing parts
(i.e. handling, cleaning, vacuum baking, installing
and keeping to the
schedule) here at LHO, I feel that we have
failed miserably with the
documentation of these events. Seeing
as the symbolic milestone that is
load #50 is set to begin soon, I feel strongly
that we should halt all
parts processing and arrange for a discussion
(conference call?) amongst
the concerned parties regarding the differences
between how the
documentation process was intended to work
versus how it is being
implemented.
Core Optics Support:
--------------------
(B. Weaver)
This week, I have been busy organizing COS parts for the ETM Telescope
Assembly, Beam Dump Assemblies, and PO Mirror Assembly. This has included
lots of paperwork, ordering of installation tools, integrating
parts into the vacuum bake oven schedule, and receiving parts from
the
bake oven. I just received the hardware for the APS PO Telescope.
Bartie and I will clean it and get it into the bake oven the week of
Aug. 9th. Tomorrow (Friday), I am going to receive from the bake
oven
the 6 APS telescope mirrors which were put into the load with the
Beamsplitter. The next load will be a stainless steel load of
LOS
structures which will also include some misc. COS stainless steel parts.
Seismic Systems:
----------------------
(C. Gray & H. Radkins)
BSC5-ETMx
We received the X-Fine stage components and despite a few missing items
and incompatible parts, they have been assembled and installed.
The
Airbearing/Coarse U-V stage is next followed by the Crossbeams to
complete the external buildup. We expect this to be completed
by 8-6.
Additionally, staging and preparations for the in-vacuum buildup
continues.
CAS-RACK
The Coarse Actuation System Rack has been rewired (just 8 wires) to
make
a consistant polarity between the motor controls and the motors.
We are
still waiting for the latest version of the CAS software that will
allow
the multiplexing to function.
INITIAL COS ALIGNMENT
---------------------
Two monuments were located in the LVEA for the alignment of the 2K FMx
&
ITMx. Assisting Doug Cook in reflectivity measurement of the
Core
Optics.
Computing:
----------
(C. Patton)
Jill's NT PC is on the network, Larry's fix from last week worked.
Now
I have to find out which version of the vpn client software I need
to
install. There are three options, but no indication as to which
is the
correct one.
There have been problems with the new GC data analysis 450 computer,
fortress. I turned broadcasting off on rainier, the main server,
so
that users would have no choice but to login to fortress or one of
the
other workstations. Unfortunately, it backfired on me.
The 450 was
automounting the file with the broadcast instructions in it.
So when I
turned off broadcasting on rainier, I turned it off on fortress as
well. I have a temporary fix, but still need to figure out why
fortress
is mounting that file. None of the other workstations are mounting
it
and fortress has the same setup they have. Fortress and the new
GDS DMT
450 have periodically been locking up with the monitor going black
except for a white arrow cursor. The machines don't respond to
the
keyboard or mouse and have required cycling power to reboot them.
We
are puzzling over possible causes.
Worked with Dave Barker and John Zweizig to get accounts set up and
files
mounted between the GC server and the GDS DMT computer. This
will allow
the High School students to get access to their LHO project data at
their school.
Discussed with Dave Barker and Mark Lubinski, the possibility of the
PEM
RGA computers being on the GC network. Also, helped Mark and
Matt Smith
with directions on where to buy software for the PEM computers.
Did the usual backups, added more user accounts, ordered more supplies,
and kept the GC accounting paper work up to date.
Electrical & Electronics Systems:
---------------------------------
(R. McCarthy)
Worked on the Satellite modules for the Small Optic Suspension system
trying to eliminate a 50khz oscillation. Jay H. was able to model
the
problem and recommended a inserting some capacitors on the terminator
boards. This rectified the problem and we are now trying to fine
tune
the fix.
Worked with John W. on the control valve for the liquid nitrogen feed.
After isolating the problem we were able to control the valve.
This
however led us to the realization that our zero percent open did not
coincide with the actual position. We should have this resolved
by
8/6/99.
Physics Environmental Monitoring:
---------------------------------
(M. Lubinski)
PEM equipment and cable installation continues here at Hanford.
We have
inventoried the equipment as to location and serial number.
I am setting
a policy that if you want to use any of the PEM
equipment (installed or
not) for tests or otherwise you must let me know.
Data from installed
equipment is being logged and movement, removal
or modification requires
notification of Hanford Site Personnel.
The RGA software we are
currently using for PEM measurement will be upgraded to the latest
version, because of problems with it in making files and gathering
data.
Detector installation: BSC3 stack and counter weight installation is complete except for some missing counter weight pins that still need to be baked in Pasadena. Cable installation is in progress, electrical feed thrus are being installed and the dome will be replaced on Friday in preparation for pumpdown.
Electrical installation: Suspension stand is assembled and has been tested per the Suspension Controller Software and Cabling Test Plan. Cleaned up all the CDS racks in the Mass Storage Room. All the mounted equipment is now in its permanent place and the cables and fibers have been labeled per the drawings from Rolf. Received the suspension controls rack drawings (1X6 & 1X7) from Jay as well as the boards for the crates and 3 of the 4 SOS controllers. The last SOS controller is in test. Received the cable shipment required to make the connections from the Mass Storage to the LVEA. Installed crate in 1X20 (south end) for data acquisition. Communication between the crate in 1X20 and Mass Storage is operational. (Rus Wooley, Juilien Svoboda)
Bakeout Oven: We are baking ISC viewports, and are preparing
to bake COS viewports.
Computers: We are in the process of upgrading software packages
for Solaris 7. (Tom Evans)
Beam tube bakeout: Pump out of the x arm is proceeding well and pressure is 3E-7. Cryo pumps for BT bake are all installed and tested. Work on the bake RGA is close to completion. We have purchased CB radios for bake out communication and they appear to work well. DC wiring is complete, and a test start of one of the DC power supplies is on-going. (Allen Sibley, Kerry Stiff)
Suspension Test Stand Network connection established to ioc for
Stand
Weather Station Lightning surge protection installed at tower
and under floor near weather ioc. Weather Station code debug mode turned
off and code changed so that one can still run debug software while testing
continues. Power losses and problems with ATM switches have made it hard
to disintangle these problems thus making it hard to test weather Station.
Weather Station did run 6 days with lockup occuring at the end which is
likely due to computer modifications
that were being made at the end of that 6 day period. New test began
yesterday (8/4).
GRASP Optimalf now working on LIGO data. We have ran sample
chirps generated from Mathematica into ADC directly and it successfully
found these. We ran the Mathematica generated chirps into speakers and
found that the algorithm did not find the chirps. Several non-flat frequency
responses were found to be responsible; work continues to quantify transfer
functions for various elements. Prof. Joel Toline has shown much interest
in the computational and data anlysis aspects of this work and was at the
site last week getting up to speed. Snapshot program written so that one
can look at segments of
LIGO data. Bug in program currently limits one to one or two second
time periods. The dcu which has been monitoring seismic data in the mass
storage room has been moved to the south end station by Rolf Bork and A.
Rizzi to continue these measurements in a place with less man-made noise.
Successfully read binary format LIGO PEM data into Mathematica.
Servo Test Stand An epics area for compiling code for the Baja
4700 processors has been installed on CDS network by Rolf Bork. (Anthony
Rizzi)
ISC sensing tables (MZ for K. Mason, M. MacInnis, M. Smith)
----------------------------------------------------------
Preassembly of ISCT10 is complete and components are packed
for shipment this week.
ISC supervisory control code (Ed Daw)
--------------------------------------
This week I have been working on the Asc supervisory code
that Peter Fritschel and I have been working on. Some bugs
have been fixed; work is still in progress. I have also
been working with my student John Leffingwell in preparation
for our site visit to Hanford on 23rd September to install
software and hardware for picomotor controllers.
ISC fab/installation (Matt Smith)
----------------------------------
While I was at Hanford last week we received two of the optical lever
platforms and support structures for the yend and ymid stations.
I had
them moved to the Y mid and Y end station where I cleaned them and
had
brought them into the buildings. I had assembled the kinematic
plates
for the installation of the tables. The Optical lever assemblies
for
the Y2K ETM is also staged at the ymid building. We will not
actually
install the platforms untill the Y2K ETM is installed and aligned.
I had aslo modified the 2K BS optical lever transmission assembly to
eliminate potential inteference when the chamber is pumped down. Made
the assembly to cover the open space between the Y2K fold mirror oltical
lever photodiode, but was unable to install it without intefering with
other tasks.
Some parts have started to come infor the ETM transmission assembly.
Assembly has started. I sent Jay Heefner the parts for the quad
diode
assembly, which are due to arive on Thursday.
I had also worked with Peter, Rana and Mike on the fixture I had made
for moving the small optics suspension. It was used to move the
SOS and
worked fine.

Lasers and Optics -- J. Camp
(1.2.1.1.2, 1.2.1.1.3, 1.2.1.1.4,1.2.1.1.5)
--------------------------------------------
Prestabilized Laser -- Peter King
--------------------------------------------
- This week PSL took delivery of laser SN #109.
SN #109 is fitted out with a
new actuator, a current shunt, to control the
intensity of the laser. R.
Abbott's current shunt concept, was tested at
Caltech last year and was
found to have merit. But due to suspected
development time, the
acousto-optic modulator approach to regulating
the intensity was pursued
instead. Lightwave Electronics have now
adopted the current shunt approach
for the 10-W laser. [Congratulations
Rich! - GHS]
Tests conducted on SN #109 show that the actuator is close to a single
pole
at around 2 kHz. Using the new actuator, the intensity of the
laser was
stabilized to within a few dB (approx. 5 dB) of the PSL intensity noise
requirement after the modecleaner. The in and out of loop measurements
are consistent with each other. The new actuator removes the
need for an
acousto-optic modulator for intensity control.
Given the ease at which the intensity was stabilized, the new scheme
is to
be implemented straight away for the LLO PSL.
Input/Output Optics -- Dave Reitze, UF
-----------------------------------------
LHO:
- The MC was realigned ny Rana and Haisheng to improve performance.
The
visibility is now 75-80% with one glorious moment where 91% was achieved
(although the lock at that point was a bit noisy due to the low optical
gain).
- The PSL/IOO table continues to suffer from dynamic misalignment
problems. Suspects include the AOM - Rana and Guido measured
the power
before and behind the output polarizer (behind the AOM) while playing
with
the RF-power driving the AOM. The results were surprising. At one point
birefringent is the culprit. In addition, we suspect that a thermal
gradient is set up due to the uniform heat input but nonuniform boundary
conditions for the crystal: heat sink is only at the bottom, which
could
result in an index gradient which deflects the beam. Basically,
any time
the PSL loses lock, a dynamic gradient is set up.
An investigation is underway - two quad diodes will be placed on the
PSL
table to monitor the drift.
- All T-mounts have been replaced by DLC mounts.
- MC's length has been readjusted. Now the length is <1 mm
shorter than
the designed value.
LLO
- Two MMT3s have been shipped to LHO.
Core Optics Procurement and Metrology -- GariLynn Billingsley
-------------------------------------------------------------
We received SPETM06 on the 3rd of August and have begun characterization.
We have performed transmission measurements on two pieces of suspended
sapphire. We will need to measure the surfaces to be able to
correctly
determine the homogeneity of the material.
Core Optics Coatings -- Helena Armandula
--------------------------------------------------
Scatter measurements of SPETM06:
SPETM06-A seems to be an acceptable part. There
are no large defects. There
are some smaller defects, but none are close
to the center. None of these
defects saturated the lock-in amplifier on the
10 mV full-scale setting.
The mirror was delivered to the Metrology Lab.
for further characterization.
Core Optics Support -- Michael Smith
------------------------------------
PO TELESCOPE
Mike S., Ken M., and Paul K. disassembled, cataloged, packaged, and
shipped
the 2K APS PO telescope to arrive at LHO on 8/5 for cleaning and baking.
ETM TELESCOPE
Craig C. designed and fabricated an adapter bracket to attach the velmex
slide mechanism to a vertical support tube for alignment of the ETM
telescope in BSC6. A production contract for 6 ETM telescopes has been
let.
STEERING MIRRORS
Yehuda shipped 15 sets belonging to IOO, some of those will be kept
by COS
in return for the borrowed ones.

The ETM PO beam vacuum window beam dump was fabricated by Ken M. and
Mike
S., and will be shipped to LHO on 8/5.
VACUUM WINDOW
The o-rings for the vac windows have been shipped from LLO to Yehuda
for
cleaning and baking.
COS IR ALIGNMENT SYSTEM
The COS IR alignment sysem was tested and verified by Mike S. in the
lab at
CIT. It will enable aligning the pick-off mirrors, and telescopes to
better
than 50 microradians. It can also be used to correct the misalignment
of
the FMy and FMx mirrors. Craig C. designed an alignment target for
the
cavity beam dumps.
ARM CAVITY BAFFLE
Quotes are being received for the inner frame assembly (surfboard
glass-mounting structure). Paul K. is in process of detailing the external
frame and
the glass plates.
CONICAL BAFFLE

1. Electronics Rack :
Hytec is currently testing and debugging the mobile rack and anticipates
to
complete the testing tomorrow. No progress was made on the assembly
of
#4 rack this week due to scheduled vacation. The work will resume next
week and the expected completion of the rack is still 8/13.
Suspension -- (Janeen Hazel/Mark Barton/Mike Fine)
-------------------------------------------------------------------
1. Report from Janeen:
-Mark Barton is at LHO. He re-balanced the BS
and assisted in putting it in
the oven for baking last night. He is inspecting
and re-hanging the ITMx in
preparation for installation next week. The ETMx
will be at LHO on Aug.
23. As
I will be at LLO, Betsy and Doug will suspend
it.
-The Mike Smith's broken glass, which I'll use for the little beam
dumps, was
sent to Cascade Optical Coatings this morning for cutting and coating.
Fabrication of the metal parts will start as soon as possible

---------------------------------------------------------
Global Diagnostics System
(Daniel Sigg, John Zweizig)
This week I continued the setup and system management
functions for the DMT machine at LHO. This included installing
the secure shell and writing scripts for starting and stopping
various DMT functions.
I have also worked on improving the documentation for the
DMT and have modified the sources and distribution files of
the DMT software to make them compatible with linux.
Added a self-configuration utility to the diagnostics test tool.
Diagnostics services such as the arbitrary waveform generator
now announce their capabilities on the net. Clients such as the
user interface can then query this information and setup
their own configuration accordingly.
Added a channel query function to the API of the arbitrary
waveform generator. This will allow the user interface to
setup GUI tools for selecting excitation channels by name.
Received the Ultra10 for the DMT frame builder. Started
to perform network throughput tests to see how fast
gigabit ethernet is compared to ATM OC12.
Lost some recently written lines of code when spica (software
repository) was hacked. When the cvs (version control
system) came back again, it overwrote some new files with
older versions.
Physics Environmental Monitor (Matt Smith, David Shoemaker)
-----------------------------------------------------------
Last week at Hanford we finished the repositioning of the PEM stay clear
zones, which now can protect the seismometers and tiltmeters in each
of
the buildings.
I installed the PEM interface plates on BSC6. The accelerometers
have
not yet been installed to these plates.
I installed accelerometers to BSC4 and 7. Worked with Dave Barker
to
verify the accelerometer signals were working for the PSL2, HAMs 7,8,9
and BSC4, 7 and 8. Accelerometers for HAM 10 will be installed
after
the 2K BS is installed and the spool between BSC4 and Ham10 is
installed.
Worked with Mark Lubinski on PEM issues.
I had set up a new drawing, D990256 and reference list that identifies
the locations for all PEM sensors in each building, the assembly drawing
for the sensors and PEM equipment, the serial numbers, cable
identifications and other pertinent information.
I had fitchecked the assembly for the microphones and came across a
few
problems that need to fixed befor I can install the microphones.

The Visitors Program Proposal to NSF for the period Feb. 1, 2000 - Jan.
31, 2003 has been completed, after numerous rewritings, corrections,
alterations to the budget pages, etc. The budgets have been approved
by
OSR and the proposal has been sent to Prof. Tombrello for his approval.
Following his approval, it will be submitted to NSF via FastLane.
Special thanks are due Rita Torres and Donna Tomlinson for all of the
help
that they have given me throughout this process.
Follow-up activities vis-a-vis the Amaldi Conference have continued,
answering various inquiries and requests, as well as trying to complete
our bookkeeping. In addition, many e-mails and calls relevant to
choosing a publication mode for the Amaldi Conference Proceedings have
been made. A final decision will be made shortly; then the real work
begins.

TECHNICAL CONFIGURATION MANAGEMENT (Althouse)
No report this week.
GHS note: Mike Z., Cas Scilowicz (Caltech Safety)
and I traveled to LHO this week for the annual safety audit. Things looked
pretty good there, with some action items being documented. The team at
LHO is to be conmmended for way in which safety has been adopted into the
working style.
The schedule constraints for this process are:Developing and adopting a Standard Operating Procedure and associated check list; Requiring that LN2 traps be cold and stabilized at both ends of BT module before opening; Requiring that only ion pumps & LN2 traps be used [i.e., no mechanical pumps on VE] before opening to BT; Requring that pressure logging be enabled to track BT exposure; Authorizing a [single] designated individual to review RGA data before
opening interface valves for the first time.
[i] Detector requires access to Y1 module at LHO begininng
the week of 8 Spetember[ii] Detector needs to vent and complete integration inside
the Y arm midstation BSC beginning with last week in August.[iii] Before the beginnig of [ii], it is required that the
pump down performance and residual gas analysis be performed
for the Y arm midstation VE isolatable volume. This test
must include pumping down to the point were the LN2 trap and
ion pumps alone are pumping on this isolated.
Biplab Bhawal, Sam Michelle Kingham, Sam Mandegaran

[ Xiao Hu ]
* (XHU) worked on binaryinspiral ilwd file
* (XHU) worked on unique id store procedure
[ Bruce Sears ]
* (BS) Ilog system:
- The Ilog system now contains
a rather large and
complex set of information
about users in regards
to web access, read-write
access to particular logs,
contact information,
etc. I have created a fairly
extensive user information
check program in order to
make sure all of the
information about particular
users and their conection
to the Ilog system stays
current and consistent.
This program checks
the following:
* Checks and reports
on consistency between the
htaccess and htpasswd files which give the basic
access to the ILOG system for all users.
* Verbose output returns
a list of all web
authenticatable
users in the ILOG system.
* Checks the configuration
files for each ILOG group
and compares
the lists of write-access user
particular
to the group against all web access users.
Also checks
general consistency in each config file.
* Verbose output lists
read, write, and super-access
users
on a per group basis, as well as defunct users
from each
group.
* Checks group config
files against the user contact
information
database to be sure no-one who has write
permission
is without contact information.
* Parses all log files
to get all entry authors for
each group,
to be checked against users specified
in group
config file access lists as well as against
users
listed in the contact info database.
* Verbose output lists
all authors of entries in each
group's
logs.
* For defunct users,
the contact info database contains
an "other
contact" field. The contents of this field
are checked
to be sure "other contacts" remain current.
* (BS) VRVS Video-Conferencing System:
- Started looking into a
possible video-conferencing
system for general LIGO
use. [AL NOTE: I used this while participating in the
HEP+LIGO discussions on developing a computing white paper
to NSF and I was
satisfied that I felt we probably will eventually want this capability
among LIGO Labsites (and elsewhere)].
Hanford:
Nothing to report.
Livingston:
Nothing to report.
CIT:
Ed Maros has upgraded the systems spica, denebola and capella to Solaris
7.This
was done due to the need of LDAS software systems to run on that operating
system.
Larry with the help Heather Sherman from ITS has been able to install
new Cisco
7206 router with 100 Megabits/second data trasfer rate. Now LIGO has
been
connected to CITNet 2000 backbone through a fibre link to Kellog. Both
125 and
115 subnets are connected to this router through 100 Mbits/sec duplex
ports.
This will eventually substitute Sirius as inter-subnet gateway by increasing
the
bandwidth by ten folds and subsequently downsizing the network overhead
to
sirius. However, this is still on the testing phase, one can select
either of
the port ip address to route directly outside of LIGO. Presently, we
are running
two routers (old nad new) simultaneously acting as an alternate routing.
Eventually new router will replace the old one.
Suresh is still working on secured shell compatibility issues. Inability
of
secured version 1.0.1 for Macintosh has been temporarily resolved by

INFORMATION - Teleconferences - - Reminder
The Caltech operator can accommodate a maximum of 6 parties on a teleconference (7 or more must use the more expensive AT&T operator). At the maximum 6 parties, everyone must hang up whenever there is a difficulty so that the operator can reconnect the problem line. At 5 parties or less, the operator simply reconnects the one line while everyone else remains connected.

Since I was unable to send a proper report last week, this report covers a three period less the one week I took as vacation.
Worked on preparing the paper work for 52 new trips taken recently (52 Purchase Requisitions (this figure includes the travel arrangements for the SURF Students) and 21 Advance Requests). There are approximately an additional 12 new trips in various stages pending completion of travel arrangements before the paper work can be completed.
Completed the arrangements for our LIGO/SURF Students' visitation to LIGO/Hanford. There will be 12 students, plus Ken Libbrecht, traveling this summer to LIGO/Hanford. They will be departing on August 12th and returning on August 13th. A number of the students have requested a layover on the return in Seattle for the weekend of August 14th and 15. There will also be 3 SURF's coming from Hanford and 1 SURF from Livingston coming to Caltech. These four will be arriving at Caltech on August 5th and departing on August 6th and August 7th.
Completed 42 Expense Reports, some of which were extensive, involving 2 or more pages each. Many of these reports were still not taped or completed by the Traveler, and required additional time for completion. Also worked on a number of problem issues which required a good portion of my time. There is a considerable number of Expense Reports still to be done.
Attended a couple of ORACLE meetings and had additional discussions with various ORACLE personnel. Travel has yet to be worked out and things are in a state of confusion. It is very difficult to get things through or out of the system.
Prepared Travel/Vacation Itinerary for the Week of August 2nd, 1999.
Performed miscellaneous duties as requested by various members of the LIGO Project here at Caltech, as well as from members of the staffs of each of the two (2) sites. I continued to do MIT's travel to the sites for installation activities.

Attended two ORACLE-related classes on grants management. It was more like grants observation. One was the ORACLE Grants Management class. The other was the somewhat more user-friendly WEBSTER. Florence Kaufman is also a fountain of ORACLE information and gave me some excellent guidance.
Spent some time attempting to create a FileMaker Pro version of the Payment Request form. We have it in EXCEL format but it could be more useful if it were also in a FileMaker Pro format.
Solved a problem with the reconciliation of Larry Wallace's p-card. It wasn't our mistake, it wasn't the bank's mistake; the company actually overcharged us.
Made arrangements to get an estimate for repairs to the partition in the SCR. The work will be done by an outside contractor, not Caltech's carpenter shop.
Dealt with a multitude of personnel issues.
