Beginning Monday January 17 we will replace the Project Control Meeting with a weekly meeting of the LIGO Laboratory Executive Committee. This change reflects the shift in the Laboratory's focus and attention from the LIGO I construction project, which is now very close to complete, to a broader set of programs and activities.
Ahead of us lies managing the continuing installation and commissioning of the LIGO I interferometers, the establishment of interferometer and observatory operations, the Laboratory operating program, LIGO I data analysis and computing, advanced detector R&D and the research facilities at the campuses, and the development of the LIGO II construction proposal. We also have an ever increasing working relationship with the members of the LIGO Scientific Collaboration. For LIGO I data analysis, for advanced detector R&D, and for LIGO II, the LSC is now playing an integral and critical role in carrying the LIGO program forward. The old Project Control Meeting served us well in focusing the management team on issues needing attention, and on our progress in LIGO I construction. The other activities mentioned have progressed well, but now require the same kind of visibility and attention.
The LIGO Lab Charter describes the Executive Committee. The membership of the ExComm, following the Charter language and the Lab org chart, is Barish, Sanders, Weiss, Shoemaker, Lindquist, Coyne, Whitcomb, Lazzarini, Weinstein, Raab, Matherny, Coles, Stapfer, Prince and Libbrecht. This group should attend the new form of the Monday meeting. In addition, Bork, Camp, DeSalvo, Zucker, Jasnow and Petrac are invited to attend the early portion of the meeting, defined below, in order to support the discussions we envisage.
The meeting will consist of two parts. From 10:30-11:30, the larger group will report and discuss issues needing attention by the Laboratory management team. From 11:30 to noon, the ExComm only will meet to discuss policy, staffing and other issues reserved to that portion of the meeting.
We will revise the form of this weekly report over the next week to better match this revised focus.
The agenda for the first ExComm meeting follows:
The LIGO Executive Committee Agenda
for Monday January 17, 2000 will be:
(Meeting time: 10:30 am Pacific Time)
Open meeting 10:30 - 11:30
Special Items: revised weekly report, technical advisory committees for LASTI, 40 Meter facilities
Installation of the seismic isolation system is complete for all chambers at LLO!
Longer lock stretches of 3 to 4 minutes have been achieved for the 2km arm cavity.
Bake Oven:
----------
(K. Ryan)
LHO vacuum bake oven load #71, consisting of HAM 6 and 10 purge air
fittings
and misc. SS fasteners, was released last week.
Load #72, consisting of misc. Al clamps, IO beam dump glass, "little"
beam
dump glass, ETM telescope lense and plate beam dump glass, has been
baked
but has not yet been released.
Optics:
---------------------
(D. Cook)
The early part of this week was spent working
with Dave Shoemaker laying
the ground work to re-align the ETMx-2k optic.
We were having to drive the
ETMx suspension controller to its limits in order
to align the optics well
enough to get the X-arm cavity to resonate. We
tried to adjust the optic
alignment by adjusting the PAM magnets while
observing the optical lever
read out. However this proved to be too difficult
as the optical lever read
outs would saturate in both axis limiting the
adjustment travel, as
well as the angular sensitivity not being what
we needed to make small
moves, but will be used as a final check.
We ended up using the SUS Pitch
and Yaw Monitors as signals for the alignment
by installing a ~10Hz filter
at the O-scope at 5mV/div., centering the spot
on the scope for the
monitored voltages. Then we moved the SUS controller
offset bias to zero,
the spot moves with it on the scope and we then
adjusted the PAM screws to
bring the spot back to zero. This technique seemed
to work well, however
the proof will not be known until we can reopen
the vacuum gate valves
sometime on Friday AM. We still have a
problem with the "break out" box
readings differing from the CDS readings. There
may also be a problem with
the optical lever amplifer contributing to the
sensitivity.
Seismic Systems:
----------------------
(C. Gray & H. Radkins)
BSC1: Finally, the Expansion Bellows leaks have been stopped,
Phase 2
completed.
BSC2: The external hardware (phase 1) has all been installed--Scissors
Tables, Airbearings, Translation Stages, and Crossbeams. The
staging for
phase 2 is complete and the dome of the chamber is off. Beginning
1-13, the
phase 2 hardware: Support Tubes, Downtube Assembly, and Expansion Bellows
will be installed. We plan to carry right on into phase 3 installation
consisting of the Isolation Stack Assemblies--Leg Elements and Coiled
Springs; and, we'll finish with COS control cable and counter balance
installation.
Other notes: We received a set of springs for HAM1. The
tentative delivery
for remainder of 4k LVEA Springs is:

(C. Patton)
Wrote up the PR for the FORE Systems ATM equipment maintenance
contract. Upgraded some of the freeware software on the server
to the
latest versions. Started upgrading guest PCs to Windows 98.
Continued network security maintenance, did the usual backups, helped
with several printer and PC problems, and kept the GC accounting paper
work up to date.
Controls:
---------
(D. Barker)
Fixed problem with PEM signals in rack 2X5. Software configuration had
a
problem, reverted back to an earlier release. PEM signals in MY and
MX also
went off line, problem was fixed with a reboot.
Installed latest netscape and XML authoring tools.
Writing guide to DMT and John Zweizig's Bit Test program for control
room
operations. John is working on making the BitTest program easier
to
reconfigure. Working with Ski on determining how to enter and display
detector signals' checkout and configuration data.
Working on making JdClient Y2K compliant, updating java script to display
year as four digits.
Installed two more Sun Ultra 60s in the control room (both are two headed
devices). This brings LHO control room up to spec with 6 Suns (plus
one
extra). New systems are ethernet based until Fore NICs show up.
Worked on DAQ to bring in the following signals:
ITMX Optical Lever
ITMX Suspension Controller sensors
ITMY Optical Lever
Sent Solaris patch clusters and fibre optics converters to LLO to support
CDS upgrades.
Installation of the seismic isolation system is complete for all chambers at LLO! Today, spring seat replacement was completed in BSC#3 (corner station). This was the last of the chambers awaiting installation. BSC#1 was completed earlier in the week. (Rich Riesen)
OPTICS: We're proceeding with staging for the RTM-y installation, as well as the ETM telescope. Mike Smith has delivered all the telescope components; we've test fitted and cleaned the optics and they're being baked today. The mechanical components are clean and will go into the oven tomorrow. I've modified our straddle to stiffen the fork arms, and we've made the changes to the BSC fixturing that Janeen and Doug have suggested. I've completed a small batch of prototype PAM screws that I'm sending to Janeen today for magnet installation, as well as a small run of extended PAM brackets. A prototype is also on the way to CIT. We will be transitioning to the Laser Hazard Condition in the LVEA, sometime late next week or the following for IO alignment, so I'm conducting training to qualify those who'll need to enter the VEAs as Basic Trained Laser Personnel. Joe Kovalik has identified what looks like movement of the PMC mirrors, but we don't have a spare and are reluctant to disassemble ours for rework. Peter King is sending us his specs, and Joe and I will get bids for the fabrication of a spare cavity. (Jonathan Kern)
We continued working on the alignment on the PSL table. The mode matching
lenses have been located properly so that a waist (0.396 mm) is formed
at the center of the second EOM, as designed. Three EOMs have been placed
and aligned. The beam has been aligned all the way to the final mirror
on the PSL table (the top mirror on the periscope), and ready to be delivered
to the vacuum chamber. A polarizer-waveplate combination has been placed
at
the PSL-IO handoff point for power attenuation. The beam profile measured
by a beam scanner fits well to the Gaussian (TEM00) profile. The level
of the Gaussian fitting is as good as the one measured at the same location
before the EOMs were placed. We measured the beam profile after the EOMs
as a function of the power incident to the EOM. When the power to the EOM
was increased from 0.5 W to 6 W, the spot size measured at 34" from the
waist decreased by about 1%. This power dependence agrees with our previous
thermal lensing measurement of the EOM by a Shack-Hartmann detector. (Sany
Yoshida)
Facilities Excavation of the erosion control ponds is almost completed. A schedule for this work has been submitted by the contractor and indicates that all of the work should be completed by the end of March (subject of course to a continuing benign rainy season). (Gerry Stapfer)
Beam tube bakeout: All RGA data for the x arm bake has been taken and analyzed. H2O, H and all hydrocarbons are well within specifications. Rai does report a small leak somewhere in the x1 module. It is very small( 1-2 E-10 torr/l/sec) and below spec, so no effort will be made to locate it at this time. Efforts for the y1 bake are well underway, and we should be ready to start soon. (Sibley)
CDS: We are now able to communicate between the facility monitoring system computer and CDS, although some refinement of the process is still needed. We can record points from the facility control monitoring system in Excel format. Samba has been installed in London (LLO CDS gateway) which allows text files from the facility control PC to be dumped into London. Rolf will work on DAQ system to integrate with those files. A further test to see the maximum points which the auto system can take will be implemented.
Other CDS related tasks completed:
Community relations: the Livingston Economic Development Council
held a meeting at LLO for representatives of economic development council
members and related organizations regionally.

2k Arm Test/ISC Commissioning (Mavalvala, Fritschel,
Whitcomb, Weiss, Kells)
---------------------------------------------------
Longer lock stretches of 3 to 4 minutes have
been achieved for
the 2km arm cavity. Some improvements were made
to extend
the lock performance: a ground loop in the mode
cleaner length
control servo was eliminated; a 2 kHz oscillation
in the laser
pre-stabilization servo was eliminated; some
op-amps which were
oscillating (and adding low-frequency noise due
to non-linear
effects) were replaced in the mode cleaner servo
amp, which
led to a ~10x reduction in frequency noise below
a few 100 Hz;
a possible source of frequency transients in
the psl loop was
identified.
The phase noise of the VCO (including the drive
electronics) was
measured to be ~2.5 Hz/rtHz.
ISC design/fabrication/installation (MZ for K. Mason)
----------------------------------------------
This week Ken finalized plans/layouts for the LLO ETM installation
and
caught up ISC drawing sets to the latest rev's. Initial alignment,
optical lever and video/illuminator drawing sets are now up to date
(as
built). Update of ISC sensing table as-builts (for those units
delivered/operating) are in progress, although this is a bit of
a moving target due to ongoing commissioning activity.
ISC design/fabrication/installation (Matt Smith)
------------------------------------------
This week we finished two of the ETM transmission monitor assembles
in
preparation for installation at Livingston. After receiving the beam
path vectors from Mike Smith I determined the hole locations for the
grout plates and provided LA and WA with these locations to drill the
holes. I am gathering the necessary parts for the site installation
of
the Y2K ETM transmission monitor assembly at Livingston.
I designed new support plates for the change in the camera assembly
for
the ETM transmission monitor assembly. The new parts should be ready
late next week.
Started the DCN process, checking drawings and organizing the DCN
package for releasing the ETM Trasnmission monitor assembly.

Prestabilized Laser -- Peter King
--------------------------------------------
- A 35.5 MHz frequency reference card has been completed and bench
tested.
A minor modification was made to the component values to bring the
output rf
power to +23 dBm.
- A pre-modecleaner servo card has been completed and bench tested.
The
biggest problem was that two op-amps were soldered in backwards, this
was
easily corrected and the board was not damaged.
Both the 35.5 MHz frequency reference card and the pre-modecleaner
servo will be tested in the PSL Lab later today.
- The hunt for a suitable PZT for the pre-modecleaner continues. The
criteria being a high resonant frequency PZT with as much travel as
possible for less than or equal to 150 V, in a tubular stack that is
physically as short as possible.

Global Diagnostics System
(Daniel Sigg, John Zweizig)
This week I worked with Dave Barker on defining, implementing
and improving the way operators will use the channel monitor.
I have also written a first iteration of a PSL monitor that looks
for glitches in the Pockel Cell drive voltage and looks for
correlations with the Fast frequency adjustment signal. I also
performed several system management functions on the DMT
machines.
Initiated a control room monitor task involving the diagnostics
test tool. The idea is to make a coherence measurement
once a day between all working seismometers to investigate
correlations at the micro seismic peak.
Chased down a software bug which effected the frame
broadcasting and resulted in invalid frames delivered to the
DMTs about every 10 minutes. The transmission now seems
reliable for hours.
Started writing the calibration client software which will be used
by the diagnostics test tool to display physical units.

I'm working on updating the Fiscal year 2000 changes on PTA's from the reports submitted by Florence Kaufman. I am also working on any change orders to subcontracts. Most of my equipment and supply orders in the last few days I have been sending to the main office to be handled by Gina Cabrera. Today, we have a new person, Gina S., who will be training in Oracle and will be helping me with the equipment and supply orders like John Broekel did in the past. Gina Cabrera is training Gina S. in Oracle. Once Gina S. gets her feet wet, she'll be sitting at John's workstation.
I am also working on having an official "Oracle" report created for open encumbrances on particular PTA's so that the next fiscal year end, or any time this information is necessary, it can be obtained from Oracle.
From: Kris Duncan <kris@ligo.caltech.edu>
A meeting is scheduled with Tina Lowenthal and other members of the Acquisition Department to re-visit the methodology by which LIGO contracts are inputted to Oracle.
The property report for the NSF has still not been submitted by the Caltech Property Department. Ed Jasnow contacted Michelle Masters, head of Caltech Property, to remind her that the extension granted by the NSF to January 31, would be the last. She indicated that she would assure that the report was submitted on time.

* (KB) The 0.0.7 build of LDAS (which has shared object loading
problems of an almost transparent nature to the TCL interpreter)
has identified a need for a stronger integration layer of
testing between the unit testing of the individual APIs and
the system testing. KB and EM held two meeting this week to
work out a new design for LDAS installations which would allow
for a more closely coupled testing at integration to the full
system testing associated with preparing each new software
revision. Implementation of the new system will require some
tools (in the form of Perl scripts to begin, which could have
a GUI front end added later). The major aims of this rework
of the testing areas is to provide faster system testing with
higher quality results and decrease the revision cycle time.* (KB) Developed a VISIO flow chart of the LDAS software construction
cycles that are associated with new software development and
released software maintenance. The drawing for this flowchart

extract a wealth of information from the database using a simple
point and click interface based on TCL/TK. He will now work with
ML to organize his SQL queries into LDAS commands to the managerAPI
will direct the metaDataAPI to make the queries based on SQL his

Barbara added some new edits to the DCC data entry system. Added a warning
message if a Log record doesn't exist when it should or if the Log record
belongs to a different revision of a document. These changes are installed
in the test system awaiting review.
Checked the problem with the missing Y2K sort fields. It was a
non-problem because we were using an old version of the test system.
Answered several other questions for Linda Turner regarding log status
codes and the Change Date field. Fixed a problem with double dashes in
some Log entries.
Worked with Dennis Coyne and Linda Turner on the plan for duplicate
document numbers when revisions occur. Right now we are planning to add 2
fields, one to cross-reference document numbers and the other to note the
type of cross-reference -- primary document or dummy document.
Began revisions to the web pages for the new round of LSC reports.
Some changes were requested by the LSC and Irena Petrac requested a new

Irene Baldon
Worked on preparing the paper work for 31 new trips taken recently or upcoming (31 Payment Requests and 16 Advance Requests). There are approximately an additional 7 new trips in various stages pending completion of travel arrangements before the paper work can be completed. Also worked on an unusually high number of problem issues which required a good portion of my time.
Completed 19 Expense Reports, some of which were extensive, involving 2-3 or more pages each. Some of these reports were still not taped or completed by the Traveler, and required additional time for completion. Worked additionally on a number of problem issues associated with these which required a good portion of my time. There are 21 Expense Reports still to be done. I'm holding 4 completed Expense Reports which require a check from the Traveler before sending to Travel Audit to clear.
I have not seen any significant change in the time lag for receiving checks. They still continue to hold checks in Disbursement Audit for up to an additional week after the check has been issued, which already adds considerably to the existing time lag. I have started receiving T numbers. We'll have to see how long this lasts this time.
Performed normal recording and filing associated with Travel and Reimbursement.
Prepared the Travel/Vacation Itinerary for the Week of January 10, 2000.
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 continue to do MIT's travel to the sites for installation activities and assist them wherever possible.

Using my trusty P-card, I ordered parts for Mike Smith and Ken Mailand.
Spent a great deal of time doing retroactive account distributions using the ORACLE system. It's not that I don't know what I'm doing; ORACLE takes its time delivering the information. Lots of time.
