The Project Control Meeting for Monday September 7, 1998 will not be held due to the Holiday
=========================================================
LIGO Hanford Observatory (LHO) Operations (F. Raab)
=========================================================
General Items:
--------------
Control room furniture is being installed today (9/3)! Beam tube
module Y2 continues baking. IOO components are being assembled.
Seismic piers are being installed and we are actually shipping parts
back from completed experiments. Preparations for laser installation
are in high gear.
Seismic Isolation Installation:
-------------------------------
(C. Gray)
A test of an alternative method for installing Support Tube into a HAM
chamber was conducted. New method greatly reduces time for chambers
to be
open; hardware for this method would pick up the Support Tubes from
their ends (along with a fixture to pick up from within the chamber
as
well).
HAM Piers for chambers 7-10 were installed (HAM 8 took longer because
a 480 V power supply had to be removed). Individual levelness
of each
Pier surface as well as w.r.t each Pier was taken care of. The
x-y
position and yaw of individual piers was made for HAM 7; other
chamber's Piers are also being fine-positioned.
Anchor bolts for 4k HAM Piers have been installed; roughing of surface
is next up.
Optics Table, Support Table, and two Support Tables from HAM 13 were
shipped out to Allied.
All Seismic Isolation hardware was removed from HAM 13. Tables,
tools,
and other items still need to be removed from area. HAM doors
are due
to be put on on 9/4 so chamber can be handed to PSI for shipment to
MIT.
Optics & Lasers:
----------------
(D. Cook)
The Standard Operating Procedure for the PSL laser on the 2K
interferometer is nearing it's final form. It is being written by Rick
Savage. Reviewed by Doug Cook, Fred Raab and Otto Matherny. The signs
and hardware needed to back-up the SOP has been ordered, along with
the safety barriers etc.
The DI water system is going through some installation changes to
improve the water quality at the dispensing stations. The water
quality at the source is fine, but breaks down quickly through to
plumbing. Air quality continues to improve as we impose more cleanroom
protocols and clean areas up. We now have a full time person dedicated
to house-keeping.
IOO optic balancing setup has started today using practice optics.
Supplies and equipment continue to arrive.
Computing Systems:
------------------
(C. Patton)
This week most of my time has been spent working on the Data Aquisition
System software, helping to get computing needs setup for the PSL
installation, and planning for moving computers into the Control Room
once the furniture is installed.
However, for General Computing, this week I have worked on setting up
user login files on the Unix system which will allow users to type
in
commands used at Caltech and have those commands work on our system.
I
have completed a first draft of a proposed '99 data and computing
budget. I will also be installing some new software on the Unix
server
and on the PCs in the common area. I am still doing weekly backups
manually on the weekend. I have recieved quotes on software packages
to automate the backup, however the software is quite a bit more
expensive than originally planned so I'm still researching and trying
other options before buying.
Beam-Tube Bake Out:
-------------------
(M. Lubinski, M. Guenther, K. Stiff and W. Althouse)
We shut down on Tuesday 9/1/98 to install additional insulation on the
bellows assemblies on the beam tube. After analyzing data from
the two
instrumented guided supports this additional insulation will bring
the
bellows up to tube temperature. We have also added additional
insulation to two instrumented fixed supports to determine what and
how
much heat loss there is through these supports.
During the shutdown Sun River replaced the main supply breaker (AC
side) in PS1. We installed a breaker from a spare power supply.
Upon
opening the breaker to "lock" it out for the shutdown the breaker went
to a trip free position and inspection revealed it would not reset.
Sun River is currently procuring parts to repair this breaker.
Sun River is building a cover over PS1 and 2 to help provide cooling
for the power supplies and has installed fans in PS1 to help in moving
the air in the Connex.
A review of the vacuum bakeout oven was held this week. We have obtained
all of the PO's from Hanford for their oven and will begin procurement.
The
oven planned for Livingston is nearly identical, although we plan to
obtain
feedback from Hanford regarding their thermal control system before
ordering those components. (Sibley)
Organization of the components shipped to the site continues. A warehouse
inventory system has been set up that tracks the location of all components
and items that are now being placed on the newly installed racks. We
are
making good use of the staging building, which right now is full of
heater
blankets, electronics racks, the laser enclosure, etc. Clean room and
regular wooden pallets have been ordered. (Riesen)
Preliminary 0.5 micron particulate measurements are being made in each
area
of all the buildings so that we can compare how the air quality improves
as
these areas are cleaned. (Riesen)
Rolf Bork was here Monday and Tuesday for the fiberoptic cable
installation. No special problems with the water filled pull boxes
were
mentioned by the prospective contractors. We were worried that this
may
complcate the job. (Svoboda, Bork).
Hurricane Earl decided to go elsewhere. We developed an emergency plan
to
secure the facility in coordination with PSI and CBI which we fortunately
didn't have to execute.
WBS 1.1.1 Vacuum Equipment(Worden)

2. X-end 100 hour pumpdown complete. 80K pump consumption test
complete. PSI
is preparing for the " Gate valve soft closure " test in this station.
Livingston Installation (Allen Sibley)
PSI has completed the pump out and leak test of the x arm end station.
No
significant problems were in countered and the pump down was well within
the
specified time of 100hrs ( aprox 18hrs.). All annuls piping is installed
and
tested.
Electrical wiring is installed and tested as well as the cryo piping
and
regen heater. Bake blankets are almost completely installed and
thermocouples are being installed for start of bake next.
WBS 1.1.2 Beam Tube (Jones)
a. Livingston Installation
CBI continues to pump on the Y arm in preparation for acceptance testing.
Current pressures (torr) are in the high E-8 to low E-7 torr range,
depending upon temperature. Precautions were being taken for
protection
from hurricane Earl, who kindly decided to go elsewhere.
The Y mid station valve is now open, to allow maximum outgassing of
the
Viton o-rings. One of the RGA circuits is undergoing a full bake (one
week
long) and one has had a mild bake to degas the local Viton. Two more
will be
given a mild bake. A "preview" accumulation of the complete arm
will be
made as early as late next week.
All turbo carts at Livingston have been reworked by the Edwards technician
to correct for faulty logic. No cart failures were experienced this
past
week. The previously failed turbo cart now appears to be working well,
without the backing pump mounted below (perhaps the vibration sensor
is
overly sensitive?).
The Balzers technician demonstrated the networking of the 10 RGAs on
one
computer on 9/1, to both CBI's and LIGO's satisfaction. This equipment
is
being palletized and turned over to LIGO. It will remain at Livingston
at
least until the Y modules have been accepted, in case of need for leak
location (in which case it will be turned back to CBI). Correction
to last
week's report: 4 of the RGA heads had been installed on the Y modules
for
acceptance testing; all 10 of the RGA rack electronics sets, along
with 6 of
the RGA heads, were used in the network demonstration.
b. Other Issues: Hanford VAT Valve Adjustments
VAT is scheduling to arrive at Hanford on 9/21 to repair the pump port
valves on modules X1, X2, and Y1. CBI is still working to determine
who's
paying for the task, but expects the issue to not effect the trip schedule.
Hanford Construction (Otto Matherny)
Levernier
All the outstanding items are complete. Levernier
has completed their
contractual obligations. At the present
time we are reconciling all the
payments and credits for the final payment.
OTHER ITEMS
The LHO janitorial work will be performed by a single individual on
a
contract basis. This is the Livingston Model and it seems to work good.
Livingston Construction (Gerry Stapfer)
The good news is that EARL has passed us by without a drop of rain.
The bad
news is, we weren't able to test the buildings for leaks.
Punch list items are continuing to be worked by Hensel Phelps'
subcontractors.
Woodrow Wilson is continuing work on the modified parking lot.

40m (Jennifer Logan)
--------------------
We have now turned our attention back to the full interferometer
locking process and are trying to investigate why the interferometer
locks stably only when one of the end masses is slightly misaligned.
In particular we are trying to establish whether there is a gain change
or a sign switch required in one or more of the loops if the
interferometer is fully aligned. In Lisa's original 40m SMAC
model she
predicted that the BS loop would have to flip sign; this has never
been
the case in practice so far. We are trying to use the DAQ to
record
what happens when the interferometer is in lock and we then try to
fully align it causing it to drop lock.

ASC Design and Fabrication (K.Mason, M.Smith, M.McInnis)
----------------------------------------------------------
Completed the design and detail of Electo-optic Shutter and Glan
Brewster Polarizer mounts for IOT7.
The optical lever support stands have been held up at the fabricator
until machined areas for the kinematic mounts are properly cleaned.
Myron and Tom Evans are preparing additional grout plates and all base
plates for shipment to Hanford.
ASC fabrication (M. Smith)
--------------------------
I finsihed the drawings for the enclosure for the Wave Front Sensor.
I have one empty box that I am having machined this week so that we
will
have one ready.
I have a second box that has holes from a previos WFS assy that I will
have machined for the second WFS
that is needed and will replace it later, when the new boxes are made.
I want to make these two first
and prove out the assembly then buy the remaining machined enclosures.
I finished the assembly drawing for the Optical Lever with the new
Photodiode assembly. The D-sub connector
for this assembly has not been delivered yet. It should be here
today.
I will fit check the connector with
the Photodiode assembly, then send the rest of the empty boxes out
for
machining. I have all the quotes
already.
Sent out a number of new drawings for quotes for IOT7. Material
has
started comming in for this assembly.
ISC Design (N. Mavalvala)
-------------------------
LSC Detection Mode
A first draft of the controls paper was circulated to co-authors
for comment.
ASC Guoy phase telescopes
Guoy phase telescopes at the reflection port WFS 2,3 and 4 for both
the 4km and 2km interferometers have been designed. Designs may need
some iteration when the detailed ISC table layouts are done.
ISC implementation (Fritschel/Daw)
-----------------------------------
o We are beginning to look at the design of the GDS/DAQ - ISC
interface with Jay and Dale.
o Started working on some of the analysis algorithms for the
GDS diagnostics tests.
o The Newport laser autocollimator to be used for initial
alignment arrived this week. Testing is about to begin.

--------------------------------------------
Prestabilized Laser -- Peter King
--------------------------------------------
- During a short period endurance test, the PSL remained locked to the
reference cavity and the pre-modecleaner remained locked to the laser
without loss of lock in either case for a period just shy of four days
before the PSL was dismantled for shipping.
- The PSL has been shipped to the Hanford site
for installation.
Input/Output Optics -- Dave Reitze, UF
-----------------------------------------
IOO Installation:
Qi-Ze is currently at Hanford. Sany spent last week there. With
a test
mirror from MIT, they practiced the optics cleaning procedure for 3"
mirrors under the guidance of Helena Armandula. They also experimented
gluing magnet/standoff assembly on the mirror. Some add-on fixtures
were
designed and send for machining. These fixtures put constant
pressure on
the glue for better consistency of the procedure. The last round
of
gluing seems to be successful. The key is probably the right
amount of
glue applied. We observed the difference of the shapes of cured glue
on
the back and the side of the mirror (they were glued 48 hours apart).
It
happened that the glue on the back, where glue climbed up the aluminum
and
formed a smooth joint with the aluminum standoff, was applied about
30
minutes after the epoxy was mixed. They then did a test of applying
glue
at different time, up to 50 minutes, after it is mixed, on a thoroughly
cleaned AR surface of a CVI 1" window. The results, however,
do not show
a conclusive relation of the time and the bonding shape. The
cleanness of
the aluminum may be a more significant factor.
In the procedure of removing the epoxy from the back of the MIT mirror
for
last round of gluing pratice, the cleaning procedure was repeated.
Several dotted scratches were found on the mirror coating after
cleaning. It may serve as an example that how easily a scratch
can be
made.
Machining and Procurement:
3" optics holders are being held up because of stock aluminum shortage.
The periscopes have been welded and will be shipped to Hanford early
next
week. We are still waiting for some in vacuum components to be
delivered
(rotation stages and polarizers for the Faraday isolator).
The coating error by REO has been corrected. The second 2 km MCCM
was
correctly coated and shipped to Hanford.
Two 10" MMT3 mirrors have been received by UF for radii of curvature
measurements.
Mode Matching Measurement:
Bullseye: I changed the demod board filter to a 2-poll 20 Hz low pass
filter and it greatly helps the signal to noise ratio with our low
frequency dithering. I also was able to reduce the tilting signal
by
re-aligning the dithering lens so now the tilting signal is in the
same
order as the bullseye signal. The bullseye photodiode was aligned with
one
mode matching lens removed so that a "bullseye" showed clearly
in the
reflected light. But the outer segments were not symmetrically
illuminated, either in DC and RF. This observation justifies the planned
use of a pre-mode-cleaner. This work will be continued when Qi-Ze
returns
to UF.
Core Optics Procurement and Metrology -- GariLynn Billingsley
-------------------------------------------------------------
(Gari is on jury duty this week. In her absence I briefly
report the following:)
CSIRO has received our beam splitters and has been instructed to repolish
both sides of BS 1-4. BS 5 is scheduled to arrive at REO for coating
around mid-Sept.
Acceptance testing of the IR interferometer after the various
reworkings at Veeco is scheduled for the early part of the week of
Sept. 14.
Core Optics Coatings -- Helena Armandula
--------------------------------------------------
REO Contract - COC coatings: REO will start coating 2ITM's next Tuesday.
I
will be witnessing the cleaning process and inspection of the surfaces
prior
to coating.
Received from REO the coated test pieces to be used in the scattering
measurement instrument and to validate cleaning process.
After resolving all issues to combine coating runs, I expect to place
the
order for the 2" mirrors to be used in telescopes by M. Smith and P.
Fritschel (MIT) by the end of this week.
Indium bonding: Attached four magnets with indium to a pathfinder test
mass
which Q was previously characterized. The test mass is suspended
and new
measurements will be taken to observe the effects of the bonding.
Core Optics Support -- Michael Smith
------------------------------------
BEAM-DUMPS:
A. Bagdalian is in the process of completing the rework drawings for
the
prototype double beam-dump.
ITM BAFFLE:
A. Rosa has completed the design of the large vertex baffle, and is
cleaning up the AUTO CAD files. The next step is to modify the design
for
incorporation into the midstation and endstation baffles.
PRODUCTION:
2 inch Steering Mirors--
The purchase order to REO for 60, 2inch HR steering mirrors has been
modified to require superpolishing of the substrates. H. Armandula
is
coordinating with ISC for similar mirrors.
Alignment Telescope/autocollimator--
An order has been placed with Davidson Optronics for two alignment
telescopes, modified for IR operation.
ETM and PO Telescope-
Bid documentation packages, including Component Specifications and
AutoCad
reference drawings, were completed by J. Kern and M. Smith and placed
on an
FTP site for access by potential bidders. Bid packages were sent out
by I.
Petrac to four potential bidders and three of them have responded with
a
scheduled proposal presentation date: CC Design (Tues 9/8am); Alliance
(Wed
9/9am); Optics1 (Wed 9/9pm? will call).
Output Vacuum Window--
A specification for the Output Vacuum Window has been completed, and
a bid
package is being prepared for a sole source procurement from ISI for
30
high quality vacuum windows.

Isolation Group -- M. Fine
--------------------------
Seismic Design (Mike Fine)
--------------------------------------
1. In-Vacuum Hardware:
Allied completed torque tests on a sample of 10-32 fasteners showing
ample
margin for the oversize tapped holes. They exceeded our torque
spec by a
factor of two, so no problem to proceed with oversize tapped holes.
Allied
has now been directed to rework all the 1/4-20, 10-32, and 3/8-24 thread
holes on the 1st article hardware to allow .005" oversize. Allied has
completed cleaning and FTIR sampling of 1 set of HAM legs and support
tubes
earlier this week, is cleaning the optical table today, and will be
cleaning the support table tomorrow. If everything goes well and the
FTIR
results are good, Allied will be shipping one complete set of HAM hardware
sometime in the middle of the next week.
2. Rack Assembly:
Hytec has installed the pneumatic components into the rack. They
still need
to connect the high, low, and bearing pressure signals. Six,
"full-length"
motor cables have been constructed; the final two should be completed
this
week.
Hytec is creating these cables to test for "worst case" cable runs
at the
Hanford installation.
3. BSC 1st Article Test:
Hytec has begun to reassemble the BSC. The hardware assembly
is proceeding
fine. They have not encountered any real difficulties, but have
been refining
the build process to streamline and to ensure that the actuator assembly
is
correctly aligned. Hytec are documenting their findings in a
report that
will be used for future assemblies at LHO, and LLO.
4. Scissors Table Testing:
The scissors table testing was slowed to assist in the assembly of
the 1st
article prototype BSC here at HYTEC. The static testing will
continue early
next week and is expected to be complete by the end of next week or
early
the following week.
Suspension -- (Janeen Hazel/Mark Barton/Mike Fine)
-------------------------------------------------------------------
1. LOS Welded Structure:
Craig has finished the LOS3 drawings. Janeen is meeting with Brookfield
today
discussing with them some LOS1 production issues and she will also
present an
RFQ for LOS2 to Brookfield. A waiver is submitted to the Vacuum Policy
Board
for the cleaning of the 5 pickled height adapters. The waiver is to
remove
the Alconox step in the cleaning procedure.

---------------------------------------------------------
Global Diagnostics System
(Rolf Bork, David Shoemaker, Daniel Sigg)
--------------------------------------------------------------------
Installed the NTP (network time protocol) services on the main
LHO servers. This made it possible to finish up the testing of the
VME GPS slave module driver. (This driver is now initialized
with the correct year information over the network at startup.)
Received the stand-alone GPS NTP server from Serap T. and put it
in the mass storage room. We still need to install the GPS antenna.
Wrote the GDS side of the interface code for accessing the channel
database. For now the information is read in from a parameter file.
Started writing the GDS side of the interface code to the network
data server of the DAQ system.
Ed D. performed a series of tests with Labview for SUN to investigate
if it can be used as the GUI for the on-line diagnostics system.
Installed the LHO web server and setup the GDS web page. All design
documents and the updated program documentation is now available
on-line at http://198.128.70.66/gds
Physics Environment Monitor (Alex Marin, Matt Smith)
-------------------------------------------
The geophones were repaired by the manufacturer and they are suppose
to arrive at MIT Thursday. We plan to make some more measurements
in order to finish the evaluation of the Wilcoxon accelerometers,
which are the primary candidates for the seismic noise measurements
above 1Hz.
The Seismometers that were to be delivered on Sept 1 have
slipped to Oct 1.
The HAM and BSC interface plates have been ordered, with a four week
delivery time.
Optical Contamination (Daqun Li)
--------------------------------
12 days ringdown data have been gathered for both cavities 2 (viton)
and 3 (empty) since the strong earthquake struct our cavity spaciers
two weeks ago. During this post-quake period, both cavities could
not repeat the pre-quake trend of -2 ppm in two weeks in cavity total
sactter and absorption losses (cavity 2: -0.01 ppm in two weeks;
cavity 3: +0.43 ppm in two weeks). At the moment, we cannot make
any
conclusions but continue to take data.
Wrote a short technical report (T980077-00-D) in framemaker format
summarizing the contamination testing results of kapton, teflon and
vacseal, which can be found at /home/dli/document/op-con-1.fm.
Characterizing the scatter property of a REO 3" flat mirror (T=1500
ppm)
recently received using the scatterometer with the Loss Scanner.

Continued to review and analyze project status updates submitted by task managers due on September 2. Began updating schedule status for the month of August with input from task managers.
Received the new Hytec schedule for Seismic Isolation. New schedule includes extensive changes. Have began process of analyzing changes and additions. This is a lengthy process and has taken most of my [JR] time this week. Expect to finish mid next week at which time I'll start reviewing the ISC MS Project incorporating any changes that may have occurred in the last reporting month.
Have been in contact with Don Scott and Scott Shirley in regards to ProjectControl obtaining a monthly electronic version of the LIGO encumbrancereports. Progress has been made. We are now at the stage where a formal memo needs to be issued to allow the Project Control group access to the "RDS" system. From there we will be able to download and sort the data for our purposes. [As it turns out, Phil and Cindy already have permissions to the "RDS" system. However, the connections have long been dormant. We need to see 1) if connection to the "RDS" system will allow us to download the extensive open commitments data, and 2) if so, how to re-establish these connections. -pel]
A contract is being prepared to Gulf Western Elelectric to perform a QA audit of the electrical and mechanical systems at Livingston. The contractor will also be tasked to perform an electrical performance audit to determine possible power savings.
Florence Kaufman provided an electronic file of the actual costs and open commitments before her assignment ended this week. I have used this file to distribute listings of the costs and commitments for all subcontracts sorted by vendor name and by account. Task managers have been requested to review this list. I have also prepared a list of costs and commitments in the "Caltech-Owned Major Equipment" accounts. This list seems to indicate that a large amount of "Government-Owned" equipment has been mis-categorized, and the task managers have also been asked to review this list.
As of the end of August additional journal entries have been submitted to adjust balances for a number of subcontractor accounts and we are waiting for the month-end M-73 report to see if the entries have been successful.
Continued working with R. Torres on new and updates of operational procedures.

__Integration Planning:
LHO Cable Tray Installation Contract
The Purchase Order to Sun River Electric Company was sent out
yesterday. The Kick-Off Meeting for the installation is scheduled
at
Sun River's facility for September 11. Bill Baldwin and Irena
Petrac
will attend.
LLO Cable Tray Draft Specification
Bill Baldwin has prepared the draft specification for this installation
using LHO photographs, sketches and redlined drawings. He has
written
a Read Me file which lists the names and locations of all electronic
files. Hard copies of all the files, redlined drawings, and DCNs
for
original release have been assembled to facilitate the final writing
and drafting two-three months hence.
__Analyses:
Lazzarini has been working with B.Sears (SRL) and R.
Wiliams(CACR) to develop an archiving method for the BT bakeout data
presently being generated [see miore below in data analysis section].
__Reliability:
Continued efforts on the CDS Control and Monitoring System (CM)
Reliability Prediction Report. The Fault Trees and Availability
calculations are complete for the CM at both Observatories and for
the
three LIGO operating modes. The predicted annual Availability
for the
CM in the 3X operating mode equals 0.9937 versus an availability
allocation of 0.9959. Given the conservative nature of the analysis,
it is believed that the CM will meet, or exceed, its availability
allocation. Report text is in the process of being written.
Substantiating reliability data on Sun Workstations, PCs and other
network peripherals was obtained via discussions with a JPL Network
Administrator and the LIGO Network Administrator. There still has been
no response from FORE Systems and SUN Microsystems to my request for
reliability data.
__Integrated Layout/Drawings:
CABLE TRAY LAYOUTS
Layouts of the LVEA (Vertex), Mid Stations &
End Stations for
the Hanford Observatory are in Document Control.
Preliminary
prints have been sent to the vendor in preparation for the formal
release of drawing and specification packages.
ELEVATED PLATFORMS
Layout almost complete for determination of platform
profile.
Final direction should be known by next Monday of
Tuesday.
Anticipate minor modification to a stocked three step platform.
SEI (counter)BALANCE WEIGHTS
Prints have been sent to three vendors for quote
of 10 & 20
pound weights. Prices should be available
by next week.
1.4.3.3 Modeling & Data Analysis (KB/HY/AL/SA)
Hiro:
Mechanical modeling: (G.Cella, Hiro, Ed)
* Cella started working on
mechanical part of the End to End model.
* We will try to include his
contribution to the weekly report
* Current status of the e2e interface
to mechanical part and some umbiguities in Cella's work have been
discussed by e-mail.
* It is scheduled that Cella will come to Caltech
from October 21st and will go to Hanford at the NSF review.
Adlib: (Biplab, Hiro) A lot of intellectual work and understanding of
ma Michelson cavity. Almost there...
Alfi: (Ed)
* Tightly coupled the reading of the description file into
the classes.
* Moved the reading of include directive from Alfi to
ALParser.
* Started work on seperation of the objects used for drawing
from the ones
used to create the file. This is an attempt to simplify the
code and
add robustness to the system.
Admin: (Ed, Hiro)
* Moved polaris to 6th floor
* Discussed with Kent
how to partition the drive
* TAMA MOU #2 dealing with the FFT program
issue has been (almost) completed.
Kent:
KB was involved in about a half dozen meetings this week with Tom
Prince, Albert Lazzarini, Dave Farnham and Phil Ehrens to discuss a
light-weight data format for LIGO. This was prompted by an immediate
need in the development of LDAS software for a definition of a LWDF
to
communimate datasets between the C++ and TCL layers, one which was
in
common with the format that would be used to distribute data to users
thereby reducing the number of data types and software libraries that
had to be supported. A couple of meetings last week with Roy Williams
and Bruce Sears brought out the possibility of using XML (eXtended
Markup Language) as a possibility for this data format. In the weekly
meeting last Friday this looked like an extremely powerful option if
a
mechanism to represent binary data in XML was found. PGP was proposed
but when the standard was looked at in more detail it was discovered
that Base64 is the proposed standard for accomplishing this. Base64
uses a mapping that takes every 3 bytes and cast them into 4 sets of
6
bits which are mapped into the character sets a-z, A-Z,0-9,+,/ with
an
additional padding character of '='. This results in a nominal 33%
increase in binary data set size, but the XML file can easily be
compressed and the Base64 data will compress very effectively being
only a portion of the character set. At this time a simplification
of
the full XML specification is being implemented between the C++ and
TCl
layers.
KB met with Ed Maros to discuss a filesystem layout for the new
Developer's Software server for the 6th floor of Millikan. The server
will have partitions and directories supporting Alpha-Linux,
Intel-Linux, Solaris, a reserve space, a CVS repository and a common
source code area. The state of the server needs to be initialized
and
KB is planning to install a new version of the Solaris OS on the box
when the configuration begins in a couple of days. In the mean time,
the wait is on for individuals to copy over files that have found there
way on to the local temp space on this machine in the past few months.
The plan is to have the server hardware ready for configuration by
the
end of this week or early next week depending on when temp files can
be
moved off.
Phil Ehrens' report:
* Discussed various models for data formatting between
the C++ and Tcl "layers" with Dave Farnham.
* Met with Kent Blackburn and Dave Farnham to discuss
the LDF[Light-weight Data Format] and the potential use of XML
as a
model for the LDF.
* Began modifications to the html parser embedded in the
LDAS interface to generalize its behaviour to include arbitrary
tags. This involves a major rewrite of some old SUN Tcl
code (800
lines of legacy code).
Dave Farnham's report:
* Using the SWIG wrapper generator, I have been able to add numerous
commands to the TCL layer to obtain information about frames
and
their underlying C++ objects (FclDetector, etc.). This
allows the
TCL layer to obtain run numbers, frame numbers, times, and so
on.
However, since the Light-Weight Data Format will be used to
communicate more complicated sets of information to the TCL
layer
(such as actual data), I can't continue along this route until
a
format for light-weight data has been developed.
* Met With Kent Blackburn and Phil Ehrens to discuss the format for
passing data between the C++ and TCL layers (light-weight data
format). Discussed modeling the light-weight data format
after XML.
* For the rest of the time I have been implementing code to parse XML
and to represent the data as C++ objects.
W. Majid:
Studying Kalman filter theory and trying to implement some simple
process using some of the available functionalities in Matlab.
Tilav:
For the last couple of weeks I have been focusing on wavelet and
time-frequency analysis methods. This is a very hot topic in many
Electrical & Computer Engineering Departments, and variety
of free
software packages are available. Many of these packages make use of
Matlab's DSP tools, some are straight C code buried under a heavy GUI.
My aim is simply to gather the C routines into one package independent
from any GUI or tools.
Lazzarini:
Working to build an archive for the BT bakeout data (4 disparate
datasets: logs; RGA scans; ACCESS realtime database; weatherstation
data). Estimated database size after baking 8 modules (both sites):
~ 1
- 3 GB. This is starting to confront some of the "interesting issues"
LDAS has been addressing in the design phase. We are viewing
incorporating the BT database as a prototyping activity. We are
considering how to represent the DB both internaly and externally
(XML). Lazzarini is building a front end (TCL/TK interface) for
requesting data; Williams is concentrating on fusing/combining the
datasets (ingestion of all into ACCESS?); Sears is working on simple
front-end display/visualization capability to view data before they
are
dumped to user's machine.
1.4.4.2 General Computing (LW/TE/SS/BK)
MIT:
1. Working at setting up mirror sites at MIT for some of the LIGO
documentation.
Hanford:
1. Creating a .cshrc_global and setup files to set paths and aliases
such that the same commands used at Caltech to execute processes and
move about on the Unix system will also work on our system.
2. Completed a first draft of a proposed '99 LHO Data and Computing
budget. Maintained a spread sheet of expenses incurred so far
this
year.
3. Followed up on several orders, got quotes on several other
items to
be ordered. Recieved and installed some new software on the PCs
and
Unix server.
4. Started cleaning out and moving files on the Unix server to
free up
space in the root and usr directories.
Livingston:
1. Working PC issues. The DOA PC has been returned and replacement sent
by HPC.
CIT:
1. The fourth PC from MICRON has died. It was a replacement for Irene's
Gateway that quit functioning. According to MICRON replacement hardware
has been shipped.
2. Barbara K. is working on getting the NT server set up and DCC web
applications installed.
3. (Barbara K.) Wrote up the results of my meetings/research about
Oracle.
4. (Barbara K.) Made a number of quick web site changes.
5. Working on the monthly backups. Most of the servers have been backed
up with plans to do sirius this weekend.
6. Finally, resolved some SUN equipment problems on the new server.
SUN
has shipped the replacement parts and we should receive them this
week.
7. Working on a number of renewal contracts as well as getting licenses
moved over to the new server.
8. Some of the people trying to send data to /dtadsk/data2
have been
having problems. One is that we are using automount and when they do
a
listing of directories and don't see the data2 directory, they
immediately think that it is not there. This is not the case, once
the
directory is "touched" or accessed on the machine they are logged into,
it will (soon) be visible. Second is that the directory did not get
exported correctly on a reboot of the machine it resides on. In this
case, the directory will not appear on other machines. It was advised
to the people affected to login directly to the machine that has the
files on it. Also, it brought up the need for having a mirrored
location to put data and other important files that need to be
accessed. This is being worked on at CIT and MIT.
9. Suresh has now upgraded a number of machines to 2.6 and it appears
that it will be a few weeks before all of the user machines will be
upgraded.
10. A number of network cables have been run and quite a few more are
to be run to accommodate the moves that have taken place.
11. The usual business of adding and modifying user accounts. Along
with going over budgets and GC equipment needs. Documentation
of
equipment has come to a halt with the PC problems and Samantha going
home for a few weeks and Larry having to limit his time.
Entered AP30 reports into the database. Continued processing heavy load of purchase requisitions, POs, change orders, check request, etc. as well as an extremely heavy load of invoices. Followed up and tracked problems with invoice payments. Continued to monitor and support the temp.

Elizabeth K. Wood
Consulted with Matthew over in Payroll about having paychecks for the sites sent directly to them rather than through the Caltech LIGO office first. It’s easier than I was originally told. I will make these arrangements within the coming month.
Began creating a database of all the long distance telephone access codes for LIGO Caltech employees.
Had many interactions with Caltech Safety over Room 32. Mark Bennett, the ergonomics specialist, came over and took a look at the working arrangements in the room. Caz Scislowicz, Safety Head, and an assistant took gaussometer readings of the room. It is well within safety limits.
Filled in for Irene while she is on vacation, doing the hourly payroll and doling out travel advances.
Continued dealing with relocation issues for LIGO employees.
Discussed with Mark Coles the possibility of changing the choice of insurance carriers for the Livingston site due to on-going problems with Cigna. I will continue looking into the situation as soon as Mark gets me the bid from another company.
Printed out many MOUs for Syd that had been in formats strange to other
computers.
Irene Baldon
On vacation this week.
