The Project Control Meeting
Agenda for Monday December 13, 1999 will be:
(Meeting time: 10:00 am
Pacific Time) NOTE CHANGE IN MEETING TIME. MEETING WILL END BY 11:00
TO FACILITATE A CCB DISCUSSION OF A MILESTONE SLIP.
We had two nice results this week. LIGO's modeling
contingent put
together a nice "swinging fringe" analysis that
will get installed as a
MATLAB code at LHO next week by Biplab. With
fearful symmetry, Rolf and
Dave now have installed capability to request
data directly from MATLAB.
Presumably you can read more about it in the
respective groups' reports.
Bake Oven:
----------
(K. Ryan)
LHO Vacuum Bake Oven load #68, consisting of BSC Isolation Stack Leg
Assembly Pins & Screws (long and short), has been delayed by a
few days.
The scroll backing pump quit only hours before the qualification scans
were to have been taken. This resulted in the venting of the
system. A
temporary pump has been substituted. The vent necessitated a
30 hour
bake of the RGA volume to "clean up" the RGA background signal levels.
Load #68 should be ready for release on 12-10-99.
Load #69 is to consist of an LOS structure, misc. SS fasteners and
several sections of VE purge air plumbing.
Optics:
---------------------
(D. Cook)
This week was largely spent on putting together an LOS installation
documents and punch lists of items needed as well as fixturing
modifications for the up and coming LLO Core optic installations. I
set
up a local optical lever monitor for the ETMx-2k as the optic table
was
going to be moved around during the air bearing work that was in process.
I will note the before and after positions in the e-log.
We had some significant core optics movment caused
by the Kodiac Island
earthquakes on the 6th. The FMy-2k did
not return to its original
position though. It had to be realigned via the SUS controller. My
best
guess from the optical lever graph would be the YAW was out by 24 micro
radians rms and the PITCH about 12 micro radians rms. The ITMy-2k housed
in the same chamber managed to return to its origin. The cause is unknown
at this point. Possibly a static charge build up at the Viton Tip safety
screws was mentioned by Stan.
Seismic Systems:
----------------------
(C. Gray & H. Radkins)
BSC1: External hardware installation is completed on BSC1 which
during
the last week consisted of positioning the airbearings and setting
the
Crossbeams on them. Now we shift to staging for Phase2--Internal
hardware of Support Tubes, Support Table/Downtube, and the Bellows.
BSC5: The receipt of the z-pivot hardware which constrains the
actuation
stacks from horizontal movements on the HAMs and the ETM BSCs allowed
us
to remove the Coarse Actuation Translators and fixturing to allow
completion of the above BSC1 work.
HAMs: No activity
Computing:
----------
(C. Patton)
Continued network security maintenance. Continued
trying to contact the
Sun representative to get maintenance contracts
renewed.
Did the usual backups, helped with several printer and PC problems and
kept the GC accounting paper work up to date.
Physics Environmental Monitoring:
---------------------------------
(M. Lubinski)
We completed the calibration of the Y BT Manifold RGA for use during
the
1 arm testing. Found that the X Mid station RGA has a problem
with the
filament. During investigation we discovered that it is shorted
somehow
and can not be adjusted. We will be replacing this RGA.
Seismic Installation: LVEA: Removed Spool piece (+X of BSC#3).
Ham's 1-4: Rotated Air Bearings to proper position, installed Zero-Pivot
hardware on Scissor Tables . Ham's 1-3: Removed all doors, leveled
Optic Tables, removed all turn-buckles from Scissor tables. In process
of setting elevations on Optic Tables. (Rich Riesen)
CDS Installation: Began fabrication of dust monitor breakout
boxes. Finished preparations for suspension work in vessels for next week.
Helped Rus to install satellite modules. Start working on integration of
facility monitoring system and CDS monitoring system. Managed to extract
every data point
from facility monitoring system in text files. Need to determine which
data will be integrated into CDS system. (Rus Wooley, Juilien Svoboda)
Optics: This week has been spent preparing for MMT-3 and RM installation next week. Last Sunday Gary, Joe Giaime and I spent the day shooting Ham and BSC flange elevations in the corner station. Tuesday, we received and assembled three of the 6 x 10' portable cleanrooms to cover the manifold during spool removals. We're also receiving and marshalling a large amount material from MIT for Ken's alignment work. In addition to this, Gary and I have been on call to keep some measure of water supplied to the corner station while the plumbers re-route our feed lines. Towed the flatbed to the shop to have the starter-motor repaired. (Jonathan Kern)
We found some of the PAM screw bracket had a different thread from the
PAM screw and we re-drilled them with clean tools. PAM magnets are being
baked at Caltech. We cleaned all the aluminum parts for bake out.We tested
PAM magnets using a suspended small optic. When the tip of the
PAM magnet is about 10 mm from the edge of the OSEM, the PAM magnets
give approximately linear motion (in terms of pitch and yaw) to the optic.
We have found that the PAM magnets can easily change the offset by +- 5
mrad. One MC Flat and MC Curved mirror have been OSEMed. The bouncing frequency
is lower than the requirement of -90 dBVpk. (Sany Yoshida)
Bake Oven: We have finished baking two LOS structures and an
assortment of SOS mounting hardware. (There are three LOS structures remaining
to be baked.) The current load is an assortment of small aluminum SOS mounting
parts.
GC Computers: We have received access codes for Caltech's AutoCad
site license, and will be installing it on several of the PCs. We have
configured one of the Suns to be a secondary DNS server and are testing
it. (Tom Evans)
PSL: There are still problems with the PMC going out of alignment.
It seems to be the mirrors in the PMC itself that are responsible as the
output beam
drifts in position over time. The drift rate and direction, however,
are not unfiorm over time. More tests are being peformed. ((Joe Kovalik)
GRASP
1) Seismic
Measured noise background at with different averaging times found noise
to be stationary within experimental error over period of at
least 20min. These noise measurements are need to generate the masses
to be used in the chirp template. Studied with David Blair various methods
of injecting chirps into the ground including using a woofer and with various
mass loading and sound damping techiques...up conversion seems to be a
problem for all methods (including shaker). Completed hi resolution transfer
function measurement of Mathematica to output of sound card with and without
an external amplifier, completed hi resolution transfer function measurement
of input to shaker amplifier to output of small PEM accelerometer. (in
the past we have taken low resolution data run for conceptual testing...these
were successfully done months ago. Taking weekend seismic data with 3 instruments
located under beam tube.
2)Software
Modification of GRASP to accept transfer function of LIGO seismic stack
completed...testing underway to verify that transfer function is treated
correctly throughout GRASP. Sabi installed excell on PEM computer and multiplied
transfer functions together and ploted as well as helped with some
measurements.
Weather Station
Planning meeting to discuss permanent LIGO/LSU weather collaboration.
Construction of complete parts list for new weather stations for end
station under way...
End to End Model
I completed the model of long arm test about 2 weeks ago. This includes
verification by hand calculation. Rick indicates that there is a plan to
begin integrating this into PSL and IOO in a week or so. (Anthony Rizzi)
Facilities After much tribulation the plumbing subcontractor for R. Price (Erosion Control Contractor) has completed the re-location of our main 4 inch water line and the system is back on line. (Gerry Stapfer)
Community Outreach
Denham High Career Days. Denham Springs High School requested a scientist
from LIGO come out to speak to the teens. In response to this, I went to
the career days and spoke to a section of consisting of about 50 high school
students and two physics teachers. The students were interested to know
about the career life and hurdles of a professional scientist...they were
interested in physics,math, chemistry and biology. I talked about the education
and job opportunities in science as well as the excitement in science.
In this vane, I also discussed LIGO and some of the issues we are dealing
with in
trying to detect gravity waves. Many students were interested in the
toy Michelson interferometer I brought for just such hands on playing and
learning. (Anthony Rizzi)
John Thacker from Springfield High School brought his senior physics
class out for a tour on Tuesday, led by Joe Kovalik. They painted a mural
on a beam tube enclosure section (our 4th mural) and were very appreciative
for the opportunity to see LIGO on the inside. Other visitors included
Ralph Shaw, professor from SLU, with his Senior Science Education class.
(Bonnie Wascom). More school visits are scheduled for next week.

Interferometer Sensing and Control -- M Zucker
(WBS 1.2.1.1.6, 1.2.1.1.7)
----------------------------------------------
ISC commissioning (MZ for Fritschel and Mavalvala)
---------------------------------------------------
Continued work on getting the 2k arm locking
debugged. The ITMy
LOS actuation path was tested and found to work
by temporarily
realigning and locking the short Michelson with
feedback to ITMy.
A 25 kHz resonance appears to grow when this
loop is activated;
while this frequency corresponds roughly to known
vibrational
resonances of the ITM, the excitation path is
not currently
understood. Immediate plans;
- map out the resonance-band behavior of the
ITM actuator
- pursue improvement of the residual low-frequency
laser
wavelength fluctuation (with a resonant MC length
gain stage
tuned to the HAM stack modes)
- realign to 2km cavity and lock.
- (possibly) implement additive offset or direct
VCO feedback
path to increase bandwidth for acquisition
Also participated in discussions on whether/how
to test the
main IFO common-mode feedback controller with
the single 2km
cavity. A strawman test configuration has been
floated for comment.
IAS Initial Alignment (K.Mason, M. MacInnis)
---------------------------------------------------
All initial alignment equipment has arrived at LLO in preparation for
the installation and alignment of the 4k MMT3 and RM.
Calculations have been made for the theodolite positions and
autocollimator orientations for aligning these two optics, accessing
them through beam tube section LBE-1A.
LIOT1 has been shipped and is scheduled to arrive at LLO on 12/16 while
Myron, and I are there to uncrate and inspect it.
### MZ NOTE: This is our first ISC sensing table
to go to LLO,
a significant milestone!
-------------------------------------------
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
--------------------------------------------
- The transfer function of the current shunt retro-fitted to the 2k
IFO PSL
has been measured. The phase and magnitude response of the actuator
is
similar to the two current shunts measured previously.
- The photodetectors monitoring the reference cavity transmission and
pre-modecleaner transmission have been replaced with modified Thorlabs
PDA55 photodetectors. In addition the steel post holder adapter has
been
replaced with Delrin adapters to isolate the photodetector from the
table
surface.
The same Delrin adapter was installed on the 21.5 MHz rf
photodetector, for the same reasons.
- The LHO 2k IFO PSL intensity stabilization photodetector was replaced
with a modified PDA55.
- In a previous weekly report it was reported
that two laser power supplies
malfunctioned at Caltech. The problem found by
Lightwave Electronics was
that there was a short in the current shunt installed
on laser #107. That
current shunt board has been replaced and tested.
The laser will be
shipped back sometime next week.
Input/Output Optics -- Dave Reitze, UF
-----------------------------------------
LHO 2k (Haisheng Rong)
We did some measurements of MC transmission.
It seems that some light power
is missing. To minimize the errors that the various
optics on the optics
tables may introduce we measured the laser power
directly at input and
output viewports.
Taking into account transmissions of all the
optics and viewports in the
beam path, we obtain the following numbers: using
the beam coming out of
APS telescope and going to ISCT10, assuming Faraday
and MMT have total
loss of 10%, T_RM=3%, T_BS=50%, T_ITM=3%, we
find
T_MC = 78%
This preliminary measurement is a low value (>90%
expected)
and if correct suggests scattering and/or MC
mode-mismatch is the
problem. More measurements are ongoing.
LLO 4k (Sany Yoshida)
We found some of the PAM screw bracket had different thread from the
PAM
screw and we re-drilled them with clean tools. THe PAM magnets are
being
rebaked at Caltech.
We cleaned all the aluminum parts for bake out.
We tested PAM magnets using a suspended small optic. When the tip of
the
PAM magnet is about 10 mm from the edge of the OSEM, the PAM magnets
give
approximately linear motion (in terms of pitch and yaw) to the optic.
We
have found that the PAM magnets can easily change the offset by +-
5 mrad.
One MC Flat and MC Curved mirror have been OSEMed. The bouncing frequency
is lower than the requirement of -90 dBVpk.
Core Optics Procurement and Metrology -- GariLynn Billingsley
-------------------------------------------------------------
Measurements of BS02 are still underway.
Core Optics Support -- Michael Smith
------------------------------------
PO TELESCOPE

MODECLEANER BAFFLE
Two sets of modecleaner baffle glass has been ordered, it should be
delivered to LHO and LLO by 12/20.
COS ALIGNMENT
Two positive laser attachment fixtures for the autocollimators were
built.
The reworked video camera mounts for the autocollimators are being
fabricated. The two additional IR lasers were sent back to the manufacture
for correcting the fiber cables.

Seismic Design (Mike Fine)
--------------------------------------------------------------------------
1. Counter Weight Production:
The Conejo Industries has not got back the hardware from their plating
vendor (who performs the passivation process on the SS components rather
than plating as was mistakenly reported last week) for some scheduling
problems, but promises to deliver the hardware next week. The counter
weights will be shipped directly to Allied for cleaning before sending
up the sites.
2. In-Vacuum Hardware:
Allied is planning to make the final shipment to Hanford next week,
which
will include 2 BSC support tubes, 1 BSC downtube, 1 HAM optical table,
and 13 stack shims. They are presently cleaning the MIT hardware and
expect to run the FTIR tests on some of the hardware next week.
Suspension -- (Janeen Hazel/Mark Barton/Mike Fine)
-------------------------------------------------------------------
1. Report from Janeen:
-Supporting various suspension tasks and working on documentation.
-Progressive Technology said they'd be delivering the spacers for
the surface mount LEDs and photodiodes on friday. The replacement
long osem heads should be here next week. They are due to quote for
additional small osem heads.

---------------------------------------------------------
Global Diagnostics System
(Daniel Sigg, John Zweizig)
---------------------------
After attending the GWDAW workshop I visited the VIRGO
group at Annecy to discuss the status of our respective root
developments and to explore whether we might find some
common needs which might be resolved with common
developments. I have been preparing updates for a new
release of the DMT software in the next few days.
Continued working on the graphical user interface for
diagnostics tests.
Physics Environmental Monitor(Matt Smith)
-----------------------------------------------------------------------
I will be in Livingston all next week to install PEM equipment:
accelerometers, PEM interface plates, cabling, electromagnetic shaker
assemblies, and pzt shaker assemblies.

Control and Data System -- R. Bork
(WBS 1.2.2)
-------------------------------------------
WA 2K One Arm Test: (Dale)
=============================
We shipped the first LSC Photodiode Interface to Hanford. My trip to
Hanford this
week was canceled in order to concentrate on the LSC schedule.
LSC CDS: (Dale)
============================
I worked out a schedule for the LSC design and
installation that fits
Dennis' schedule. I am currently working on defining
the various pieces
and
getting Mohana started on designing the Whitening
board. Rich is helping
by
taking on the RF distribution design. We are
currently studying the
possibility of developing a portion of the common
mode servo as a first
item. I
think from discussions so far that this will
fit the LSC schedule
without
much added risk.
Suspension
=========================
- 7 LOS controllers are now assembled and ready for test. Testing is
on
hold
until luna is fixed. We currently can not get the test stand processor
(or any
other front end processor) to boot. Larry is working on the problem.
ASC/One Arm Test (Jay)
========================
- The two bull's eye detectors for ISCT10 are fixed and will be shipped
to LHO
by 12/10.
Input Optics (Jay)
========================
- Three new PZT driver modules have been tested and are ready for
installation.
One is for the LLO 4K IO, one for LHO 2K IO retrofit and one for the
LHO
4K IO.
- The revised version of the IO alignment servo amp is being stuffed.
- Three WFS whitening boards are being stuffed for the LLO IO.
LSC/ASC (Abbott)
==============
1. Working on orders for parts to build the frequency distribution
system.
2. Having an additional LSC I&Q demodulator card stuffed for some
tests.
3. Prototyped an AM suppression loop with disastrous consequences.
More
diodes on order.
PSL (Abbott)
==============
1. Received the frequency stabilization servo cards and will begin
stuffing one for test followed by the stuffing of about 6 more.
2. Feeding one of the recently stuffed VCO cards to the tech shop for
initial testing to look for the source of excess noise.
Data Acquisition (Rolf)
=================
- First code released which provides Matlab functions to receive data
directly from the DAQS Network Data Server. It has been installed at
Hanford and is undergoing testing. Basic routines support getting
off-line data (from disk) and on-line data (near real-time). Basic
instructions are on the Hanford CDS web page.
- New drawing set ready for release for DAQS rack 2X5. AA filter
chassis are being installed today and system should be ready by
tomorrow.
- To support suspension diagnalization tests, there is now a request
to
add additional optical lever signals to the system. We plan to install
wiring for ITMX ASAP, as a test is imminent, and then go back and
properly design the system and put in the wiring and interface modules
for all large optics later.
ASC (Rolf)
========
- Added capability to send DC offsets to test masses and is being run
now at Hanford.
- Continued testing of Y mid station ASC/LSC controller.
A meeting of the LIGO Change Control
Board was held on December 8, 1999. The following change requests were
approved. The minutes of the meeting have been distributed (LIGO-M990349-00-P).

General Computing
MIT:
Nothing to report.
Livingston:
We have received access codes for Caltech's AutoCad site license, and
will
be installing it on several of the PCs.
We have configured one of the Suns to be a secondary DNS server and
are testing
it.
Hanford:
Continued network security maintenance. Continued trying to contact
the
Sun representative to get maintenance contracts renewed.
Did the usual backups, helped with several printer and PC problems and
kept the GC accounting paper work up to date.
CIT:
Suresh worked with Larry to unpack and install recently arrived Sun
Enterprise
450 server.
Installed new Sun proprietary Post Office Protocol (ipop3d) daemon
in mail
server acrux. This would resolve most POP mail glitches.
Completed monthly full backups. Preparing 18 GB hard drive to replace
one of
the error proned hard drive in CDS server luna.
Setup new user accounts. Helped users retrieving their lost files from
archieves and network related issues. Installed secured shell and printers
in
some PCs and Sun units.
Installed Solaris 7 in one machine in Millikan 6th floor.
Larry forgot about final exames at Caltech this week so Samantha and
Matt will
be doing the virusscan installs next week not this week.
Just as a warning there are a number of new viruses
out there. Most affect PC
machines and will cause some damage. There are
three known viruses at this time
that the present virus-scan software will not
detect or clean up. These viruses
can get into your machine through e-mail and/or
chat rooms. So be sure you know
that any e-mail attachments you open up are from
a reliable source and limit
chat room usage. Also, do not open any e-mail
that indicates you should open it
immediatly or there is some urgency to it.
As soon as the latest version of virus-scan s/w
is out we will try and let you
know so it can be down loaded. If you wish to
download the latest data for the
virusscan on your pc feel free to do so.
We are just about finished with the new ftp units. One unit with anonymous
ftp
will be on-line in the next day or two. The second unit will be on
later. The
second unit will be limited to the LIGO community. We will send out
a message
when the new anonymous ftp unit is on-line. We will move all of the
files from
the old unit to the new one. This should also help cut down on the
hacks we have
had on the web server, which has taken up some more time this past
week.
There are some problems with luna (the replacement for kater). We are
now
replacing one of the disks to take care of some of the issues. The
other issues
have been cleared up with the exception of some file protection problems.
When
these are resolved we will replace the /opt/CDS directory with luna
and take
kater completely off-line.
Barbara continued work on the LIGO II Cost Book web application.
Finished a
form for editting WBS and Risk information. Updated the Totals
form and
finished the main switchboard.
Contacted Audio Visual Services and an outside vendor about editting
the
videotapes for the LIGO dedication. Prepared a summary of the
steps and
costs involved in making the tapes available via the web.
Investigated using a web form to submit documents to the DCC.
Met with Irene Baldon and Rita Torres about updating the FileMaker
Pro
application for doing travel so it produces the forms required by the
Oracle system.
Irene Baldon
Worked on preparing the paper work for 6 new trips taken recently or upcoming (6 Payment Requests and 4 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 usual number of problem issues which required a good portion of my time.
Completed 49 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 16 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. Also assisted and advised both Rita and Liz on the preparation of Expense Reports.
Rita Torres and Liz were able to complete 7 Expense Report for me. They have an additional 16 Expense Reports in the process of completion. Thanks Rita and Liz.
I have not seen any significant change in the time lag for receiving checks nor have started receiving T numbers for the trips prior to or during the duration of the trip. I continue to receive T numbers after the completion and pay off of the Expense Report. I will be meeting with Barbara and Rita on Thursday to see if we can work in some sort of data base using ORACLE's Excel forms.
Performed normal recording and filing associated with Travel and Reimbursement.
Prepared the Travel/Vacation Itinerary for the Week of December 6, 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 continue to do MIT's travel to the sites for installation activities and assist them wherever possible.
Rita Torres
Spent lots of time over the week on travel documents, some required phone calls to obtain details. Travel documents ongoing.
For I. Petrac did change order No. 5 to MIT, obtained an Oracle requisition number. Formatted Procurement Justification and requisition for change order No. 24 with NYMA, also updated Chronology. Did edits to proposed PO with Crystal Systems, and formatted Procurement Justification. Also, prepared letter to NSF for review of the Crystal Systems package.
For E. Jasnow formatted letter to Davies Associates re: Ownership of our logo, FedExed the letter. Completed, FedExed, then distributed in-house, RFQ EJ-315 for Maintenance Services for LLO.
For P. Lindquist distributed the agenda for the CCB scheduled for 12/8/99. On 12/8 set up telecon, faxed copies, and provided other support for the CCB.
Dorothy Lloyd
Continue to process invoices for payment using both on- and off-line approval methods. Track and solve invoice problems. Entered and approved requisitions on-line (for more detail see "Cost Schedule Control Systems" report by Sarita Moore). Receiving on-line continues daily.
Continue to monitor contract funding levels and request supplements from task managers were needed.
Data entry for current payments made for both contract and purchase orders is on-going by both Jim and me. Jim continues to work on reconciling status reports and data entry in LIGO database.
Managed to get in an hour or two of filing.
Elizabeth K. Wood
Formatted at warp speed a proposal in plain TeX (LaTeX is for sissies) that Syd Meshkov asked me to do for a proposal for the Aspen Gravity Wave conference in February.
Finished entering the account distribution changes in ORACLE for LIGO staff members.
Did some travel stuff for Irene.
We've got a new postdoc residing on the third floor of West Bridge: Luca Matone, room 364 WB, x 2071.
Talked to Engineering and Science editor Jane Dietrich about getting copies of the LIGO article from E&S last year. Yes, we'll be getting more.
Did some personnel stuff.
