The Project Control Meeting
Agenda for Monday May 3, 1999 will be:
(Meeting time: 10:30 am Pacific Time)
It is very satisfying for the Committee
to see the hardware emerge from the
paper.
1. Installation and commissioning of the
detector systems at both LHO and
LLO are going well. Although there has
been a two to three month schedule
slip in some of the early milestones, this
does not appear to delay the
first coincidence operation of the interferometer
in December 2000.
2. The Committee urges LIGO to continue
to monitor the potential
contamination for the Viton materials in
the vacuum system. Successful
operation of the two kilometer interferometer
at LHO will add confidence
that this potential problem will not affect
future LIGO operation.
3. The Committee commends the progress in
developing data analysis and
simulation systems for LIGO.
4. The Committee recommends that LIGO and
the LSC cooperatively establish a
set of pacing milestones to ensure timely
completion of the LIGO software
suite.
5. The Committee urges NSF to work with
all interested parties including
LSU and the State of Louisiana to define
a plan for final resolution of the
access road to assure all-weather access
to the site.
6. The Committee recognizes the seriousness
of the recent security issues
and strongly recommends that the LIGO management
continue to pursue and
expand appropriate safeguards.
7. The Committee recommends that NSF establish
a focused review of the data
analysis and simulation systems for LIGO
before the next annual review.
Water System modification: The contractor is in process of installing
the
two additional sensors.
Parsons designer is scheduled to be at LHO April 29th to evaluate the
work
accomplished.
New staging Building: The contractor is installing the siding
for the
building and
on April 29th is placing the concrete floor for the mezzanine.
Compressors: No change.
Bake Oven:
----------
(K. Ryan)
LHO Vacuum Bake Oven A load #28 consisted of three BSC bellows and some
misc. conflat flanges and no Kapton cables as originally reported
(correction to last week's report). The ribbon cable's Kapton
insulation
was found to be shedding and required further preparation and, as such,
were not included in Load #28.
LHO Vacuum Bake Oven A load #29 consisting of elliptical baffle glass,
beam
dump glass, elliptical baffle aluminum hardware, two small optics (glue
experiment-Haisheng) and several aluminum shims (seismic leg elements)
has
started vacuum baking.
One of the seven independently heated zones of the vacuum bake oven
system
was observed to have stopped heating in the middle of load #28. This
proved
to be the result of a defective heat tape. Also, the partial
pressure of
amus 41 and 43 (in RGA volume background) have been rising steadily
over
the past few months. This is looking like a problem with the
"upside down"
orientation of the RGA volume turbo molecular pump. The pump
manufacturer's advertised literature implies that this orientation
is valid
for this pump but conversations with the manufacturer's tech people
seem to
contradict this. In any case, we are going to vent the RGA and
reorient
the turbo pump to be followed by a good ol fashioned baking.
Seismic Isolation Installation:
-------------------------------
(C. Gray, H. Radkins)
The second BSC seismic isolation system has now been completed with
much
help from visitors Gary Sanders, Bill Kells, and numerous locals.
The
isolation stack was completed last week and the Optics Table lowered
in
place. Counterweights (shy 70 lbs) and cabling were installed
and the dome
was replaced. The bellows have not been leak checked yet and
may not for
some time until the remaining chambers (Mode Cleaner Hams) are closed
again. We have moved on to BSC7 (2K FM & ITMx); the Actuation
Stack is
about 25% in place. It is going a little slow waiting for the
Actuation
Stack alignment to be completed on BSC3.
PreStabilized Laser:
--------------------
(Rick Savage)
J. Myers and I continue to investigate laser output power drops that
appear
to be correlated with water temperature excursions. The chiller
appears to
be unable to keep up with temperature excursions inside the exclosure
where
the chiller is located.
The disk in the SparcStation located inside the laser area enclosure
has
crashed. D. Barker has removed the faulty disk and hopes to replaced
the
computer within the next few days. It is thus temporarily not
possible to
control the PSL locally via computer. This does not affect the
performance
of the PSL or the data logging.
Core Optics Support:
-----------------
(B. Weaver)
Last week I had the opportunity to meet with Mike Smith, for the
first time face to face, regarding upcoming COS installations.
We
spent a good portion of Thursday and Friday afternoons going over
baffles, beam dumps, telescopes, etc. I received many drawings
that
will help me familiarize myself with most of the COS components.
We
also assisted with the installation (and removal) of the FMy in WBSC
8.
Thanks Mike - especially for the softball tips!
This week, I received the 36 pieces of glass to be used in the beam
dump assembles. I have cleaned 9 pieces and included them in
the current
vacuum bake load with the four pieces of elliptical baffle glass.
The rest
will be included in a later load. Bake load #29 (COS glass) is
expected to
be released Monday, May 3.
Optics:
---------------------
(D. Cook & B. Weaver)
With the optics installations on hold due to the gluing process refinements
and OSEM problems, we have had an opportunity to catch up in other
areas. I
have been working with Larry on some new installation tooling and
techniques which will allow us access into BSC chambers that restrict
the
use of our current equipment. We are making some minor changes to some
of
the existing fixturing as well.
The Optics and Vacuum Prep. Labs have been up graded with the addition
of
new power circuits and cable trays. Betsy and I have taken some time
to
reorganize the labs to better facilitate their use. I had an opportunity
to
work with M. Zucker in the Optics Lab measuring the amount of scattering
from the COS elliptical baffles. There was some hope that a weak signal
could be reflected from them, but they are too efficient as baffles.
"(they're just doing their job)".
I have started on a new COC installation procedure, using our new
techniques. I will be reviewing it with the detector team when finished.
John Worden and I meet with the owner of a local machine shop, hoping
for a
second source to obtain machined parts. They have CNC capabilities
and may
be better suited to machining some of our more technical components.
They
are competitive in their hourly rate to Larsen's. Both shops
will prove
out to have their strong points. Larsen has hopes of retiring in the
next few months.
Computing Systems:
------------------
(C. Patton)
Did the usual weekly backups, ordered some more backup tapes and
ethernet cables. One of the student helpers has started re-organizing
the GCnet patch panel, which is always "a jumble of spaghetti".
Contacted HP about sending our Deskjet color printer in for repair.
I have three test user accounts working on the LHO modem pool for telnet
sessions only. I'm still working on setting up the security and
other
login protocols.
Beam-Tube Bake Out:
-------------------
(M. Lubinski, M. Guenther, and W. Althouse)
We turned power off on the X2 module Sunday (4/25/99) and we are continuing
to pump on the tube at ports X2-1 and 9 with our turbo pumps and cryopumps.
We performed a leak isolation Monday and discovered our leak at port
X2-2.
We conducted a helium leak check to locate the leak and found the "H"
hardware was leaking at the 6:00 position. We checked the torque
on the
bolts and found 2 at that position were slightly loose. Upon
further
inspection the gasket had some very tiny scratches. All of the
Cryopumps
have been removed from ports X2-2, 3, 4, 6, 7 and 8. "H" hardware
has been
installed at these ports and been leak checked. Ports X2-3, 4
and 2 are
baking. The RGA at port X2-5 has been shut down and is currently
baking to
clean it up for the post bake measurements. Rai Weiss will be
out here the
week of 3 May to conduct these measurements. Sun River will be
out next
week to begin the removal of the bake equipment and preparation for
shipment to Livingston for their module bakes. We shipped 2 of
our DC
power supply trailers and 5 transformers to Livingston. Cecil
Franklin
reported that all arrived.

(Russ Wooley, Juilien Svoboda)
Optics & Vacuum Labs: (Jonathan Kern): Added two site telephones in the PSL Safety Enclosure, permitting entrants to use the intercom feature to announce themselves before entering. Installed the PolyPro sink in the Optics Lab, and assisted the PSL group in powering the 10w in the Laser Safety Enclosure. Installed and wired the Reibo drill-press in the machine shop, and used the wheel loader to dress the contractor's trailer site as a parking lot. Setup the 6" binoculars on the observing platform for NSF review visitors, and adapted the 10" Celestron for nite observing Tuesday evening. Completed the location and boring of 5 ISC pier locations, and received and began QC of 33 sets of COS viewports from Varian.
Computers: We have received and installed Matlab. We have ordered Mathematica for the Unix system. (Tom Evans)
Weather Station/Suspension test stand: Basic code(with minimal
checking) to convert incoming data logger data to the correct form has
been written and compiled and successfully tested on abundance using gcc.
Troubleshooting in VxWorks underway. Basic code(minimal checking) for I/O
written needs to be tested. Hardware for interface between VME162 and data
logger complete. (A. Rizzi)
GRASP- Frame data ported from Milwaukee with help of B. Allen.
Now able to animate frame format 40m data. Livingston ligo frame data ported
from CDS network with help of R. Bork. Work underway to make Grasp code
compatible with ligo channel label with goal of reading frame data from
ligo format. Changes in installation parameters for frame require relook
at versions of various helper applications. (A. Rizzi)
End-to-End Model - New version of alfi3 installed and latest
psl model installed from Rick Savage's directory. Last period, Rick Savage
corridinated a telcon with A. Rizzi , Biplap and Hiro. We discussed the
e2e modeling done so far and organized for future work. (A. Rizzi)
Beam tube bake out preparation: LIGO has performed the preliminary
inspection of the thermocouples on the beam tube, we found two TCs that
are buried in the insulation. A final acceptance inspection for the X-2
module will be conducted this week. We are waiting on PII to schedule this
inspection. We did a temporary fix around the beam tube penetration in
the Corner Station and West End station. This temporary fix will help control
contamination within the building caused by the insulation work being done
inside the BTE.
LLO has received the two Power Supply trailers and one load of support
equipment from LHO. The two power supply trailers have been staged along
the X-2 module to the right of port X-2-3 and X-2-7. Randy has modified
the air header to include three times as many taps. We continue to ordered
vacuum equipment, cable ties, wire labels, kapton tape and other consumable
supplies. (Cecil Franklin,Kerry Stiff)
Facilities: Construction of the access road is continuing. The
communication cables
providing telephone and computer access to LLO were moved to accommodate
the
road construction. Contrary to our fears, communication was not lost
as a
result of this move. (Gerry Stapfer)

LHO installation activity (MZ)
--------------------------------------
MZ is at LHO this week doing things like:
- COS baffle backscatter test; Betsy and Doug helped me set up
a COS
elliptical baffle and glass beam dump (just cleaned, immediately prior
to vacuum bakeout) in the optics lab to check their BRDF's. Using
a
KP-160 CCD and a Lightwave 125 laser we found preliminary backscatter
coefficients of order 10^-7 /sr for the beamdump and < 10^-8 /sr
for the
COS elliptical baffle (upper limit; only point surface defects could
be
detected on the baffle). These are referred to calibration of another
KP-160 at MIT last week against a MartinBlack test target, and a similar
measurement on a beam dump sample sent to MIT. Bottom line; as
beam
dumps, these things rule. On the other hand it'll be very hard
to see
the beam on them during initial alignment.
- Worked with Sani Yoshida on post-modulator RFAM noise from the PSL.
Puzzle of the excess broadband AM appearing in the vicinity of the
RF
carrier is deepening. We need to understand this and fix it.
Fritschel
suggested some additional tests.
-Unpacked and stowed remainder of ISC optical lever transmitter and
receiver heads for LHO 2k and 4k (16 total arrived Mon.).
- With lots of help from Larry, Corey and Hugh, I reinstalled RM optical
lever and got the beam back out. Now setting up to log alignment on
stripchart. Last week Stan and Hugh reported a _possible_ movement
of the
RM over the intervening month since installation (sort of a 1-sigma
effect);
we want to keep an eye on it.
- Doing general cleanup of ISC equipment and 2k ISCT assembly area,
shipping
empty containers back to MIT, etc.
ISC implementation (P. Fritschel)
----------------------------------
(4/22 report)
o Hiro is visiting this week, and I am working with him to
implement the ISC controls in the end-to-end model. I'll
start with simulating the lock acquisition of a single
2 km long arm cavity. There are a couple of new pieces
that we are working on adding to the e2e: a locally-damped
optic; the first internal resonance (9.5kHz) of an (COC)
optic.
(4/29 report)
o Continued working with Hiro on implementing a locally damped
optic in the e2e model.
o Reviewed Jay's schematics for the wavefront sensor whitening
boards which interface the demodulator outputs to the Pentek
ADC inputs.
IAS Initial Alignment (K.Mason, M.MacInnis)
-------------------------------------------
All remaining optical levers for Hanford have been assembled and
Shipped.
5 Base plates and 1 grout plate is being crated and will be shipped
to
Livingston today.
All the Illuminators for Livingston are being boxed and will be shipped
early next week.
Myron is assembling an ISC clean room to begin assembly of ISC tables
for the 2k dark port and reflected port.
The Initial Alignment procedures T970151 has been revised and includes
all 2k optics alignment. A preliminary copy for review can be found
on
the Caltech ftp site at /pub/kmason/T970151-B1.PDF.

PO TELESCOPE
SORL still estimates that polishing will be completed for 6
sets of parabolic mirrors by 5/15. Mike S. is working on the
CCD camera
alignment proceedure for the telescope. Brackets are being designed
and
fabricated to hold the CCD cameras. A dummy primary and secondary mirror
have been fabricated for testing of the alignment proceedure.
ETM TELESCOPE
Fabrication of a first article ETM Telescope is ongoing.
CAVITY BEAM DUMP
Paul K. is assisting with detailing the beam dump support
structures. Craig C. has simplified the beam dumps by using an AR coated
flat black glass instead of a cavity beam dump to dump the 2nd order
ghost
beams. He has also eliminated several horizontal support structures
by
supporting two beam dumps from the same horizontal support structure.
The
horizontal support structure cross section was increased to support
the
additional weight. The glass for the beam dumps has been fabricated
and
shipped to LHO for cleaning and baking.
VACUUM WINDOW
The conflats have been received from Varian. The AR coated windows
for the
APS beam have been received from REO. Helena A. will scribe part numbers
on
the windows before they are shipped to Jonathan K. in LLO for clean,
bake,
assembly, and leak test of the completed window assemblies.
ARM CAVITY BAFFLES
Paul K. is continuing to work on detailing shop drawings for the ITM
and
ETM arm cavity baffles for LHO and LLO.

Global Diagnostics System
(Daniel Sigg, John Zweizig)
The documentation of the GDS final design review has been finished
and sent to dcc and committee (T990013-A and T990018-A).
Finished a prototype version within the DMT environment of a data
quality scanner to be used in the characterization of the 1994 40m
data.
This project is now waiting for a further development of the trigger
interface which will be used to log the data quality statistics to
a
database, underway. Also continued general analysis tool
development and debugging, in particular those functions used by the
data
quality monitor.
Started preparation of the FDR presentation on the DMT.
The capability of using channel names to select digital test points
has been added to the test point manager. Also, a keep alive function
has been added (transparent to the user), so that test points from
clients which abort abnormally are released automatically.
Physics Environmental Monitor(Matt Smith, David Shoemaker & Alex
Marin)
-----------------------------------------------------------------------
We are trying to finish up all the procurement for the PEM supplies.
Some items that will be orderded are two spare tiltmeters, the
Temperature /Humidity sensors for the partical counters, tripods for
the
magnetometers, and computers for RGAs.
Some more work is being done on the microphone suspension system. The
HAMS will require an additional support bracket since there is nothing
physically on the HAM that can be used directly.
The seismometrs delivery slipped another month to May 24. We are
getting a free Hand Held Control Unit (worth 1K) for our troubles,
though.
Getting quotes to purchase the computers for the RGAs. We will
also be
able to return two RGA heads and electronics that are a surplus.
We may
have to pay a restocking fee.
More work has been done for the muon detector final design. It will
be
presented next month and parts will be ordered.
We are revising the final channel count both in Hanford and Livingston.
(with Daniel Sigg and Rolf Bork). The scheme proposed by Daniel for
the
LHO will be adapted for the LLO IFO.

Control and Data System -- R. Bork
(WBS 1.2.2)
-------------------------------------------
Suspension
===============================
- The rack drawings, system drawings and cross connect list for the
Y-arm, mid
station rack are complete. Cross connect wiring and rack assembly will
be
completed by Hanford site personnel.
- We have borrowed one XYCOM 220 from the 40 meter WFS system to get
the
Caltech
suspension controller test stand operational. There is a shortage of
modules
between the sites due to shipping delays from the manufacturer. Until
more
modules are received the Hanford and LA suspension test stands are
on hold and
operation of the LVEA COS suspension systems is limited to 3 optics
at any one
time.
ASC
==============================
- The design for the WFS whitening board is complete and board layout
will
begin
next week.
- The board layout for the WFS DC signal DAQ interface board is complete
and
being checked.
- The board layout for the WFS Demod rev B modules is complete and
being
checked.
- A 4 bit attenuator was tested with the amplifier design used in the
WFS PDs.
The amplifier/attenuator combination showed reliable performance to
freq
greater
than 200 MHz with attenuator induced phase shifts < 5 degrees between
high
gain
and low gain modes. These attenuators will be incorporated into the
next
generation of the WFS PD board.
- The WFS demod board was tested and performance confirmed to frequencies
greater than 75 MHz. LIGO requires operation to ~70 MHz.
- Design of the Quad PD board has been started.
Timing System:
===============
- Due to a problem with the Protel PCB layout of the GPS Clock Driver,
the
board had to be completely re-layedout. I am doing the final check
of the
board before it goes out for fab.
LSC CDS:
==============
- Completed the design of clock fanout for the Pentek ADCs. This will
take
the clock out of the GPS Clock Driver, translate it and send it to
the
whitening boards to be input into the front end connector of the ADC.
Continuing work on the LSC servo for the Hanford 2K One-arm lock.

From: Kris Duncan <kris@ligo.caltech.edu>
No report.
LIGO QA (Bob Vincent) participated with GNB to evaluate how gate seals (o-rings) were being measured to verify correct inside diameters. This investigation was prompted by the recent dimensional changes reported by GNB for two of the four Fluorel o-rings processed by Walker & Sons. Mr. Vincent also provided a "pi" tape as an alternate method of measuring o-ring diameters. The conclusion was that the existing GNB measuring methods were less "reliable" compared to the pi tape data. It was agreed that in the future, O-ring diameters will be measured by using the pi tape.
LIGO QA (Bob Vincent and Bill Tyler), witnessed the diameter and cross-section
measurements of recently baked (by R. Weiss) Fluorel o-rings. Also witnessed
the assembly of the stick test gate and seal plate. The heat up of this
hardware was started late Wednesday, 28 April. The test is scheduled to
end on the 6th of May when the chamber will be vented and the gate separated
from the sealing plate to determine the amount of sticking and/or surface
deposits from the o-rings. This effort will also be witnessed by LIGO personnel.
Livingston:

CIT:
Barbara updated the web pages on the main LIGO server. Working on setting
up web
access for the bakeout data.
Sean has finished building the replacement for canopus and should be
making the
swap in the next few days. Worked on the sendmail configuration to
address some
of the mail relay issues. Has also put in a script to rotate the log
files on
the servers.
Suresh has changed the subnet access on a number of PC's to where they
are now
on the new network. This was in result to a cable being broken in the
ceiling on
the old subnet. He has also moved a number of computers around. Is
working on
the migration of pollux to replace sirius. Worked on a couple of tape
backup
issues.
A number of procurement issues have been addressed and currently working
on
getting things set to send in machines as part of the trade-in purchases
made
some time ago. We have a number of FORE items being purchased and tried
to get
the maintenance contract set to where all of the items will on one
contract.
Working on rearranging the computer room and getting some of the old
dead
equipment removed.
Worked a number of modem issues as well as setting up a number of accounts.
A
list of old accounts will be sent out for approval for removal.
Working on updating documentation of the server room and related equipment.
Received the cisco router to replacment and will be working on it next
week.

Came to Louisiana early to help Mark out with an outreach demonstration
at
the North Shore Mall in Slidell. The two administrative assistants
demonstrated sound waves and polarized light while the Ph.D. physicists
looked on proudly.
Helped Bonnie with the NSF site review.
Tried to locate subaccounts for Bonnie to attach to account numbers.
It
seems that yes, we need subaccounts, but no, we are not allowed to
know
what the subaccount numbers are. The release of subaccount numbers
could
mean the end of the civilized world as we know it. Our thanks
to Phil
Lindquist and Joann of the PMA office in tracking down at least a few.

done in Frame while the rest was done in Word. It took a couple
of days to
convert (actually to redo) these sections in Word.
For L. Wallace/A. Lazzarini continued to gather pricing information
from
companies offering pagers with email/voicemail capability. Submitted
my
report to Larry who will obtain finer details.
Got a chance to purge old email files. Our recent server problems
apparently caused files to multiply because I found several copies
of the
same message beginning in October/November. Many messages appeared
this
way causing the count (or memory) to read over 16,000. I've reported
this
to S. Singh.

Purchase Requisitions and 7 Advance Requests). There are 12 additional
new
trips in various stages pending completion of travel arrangements.
Still receiving inquiries and requests for travel from LIGO/SURF participants.
At the moment I'm working on 1 from Caltech to Hanford, WA; 1 from
Caltech to
Livingston, LA; 1 from Pisa, Italy, to Caltech; 1 from Missouri to
Caltech; 1
from Shreveport, LA, to Caltech; 1 from Lyon-Satolas, France, to Caltech;
2
from Leicester, England, to Caltech; and 1 from Belgrade, Yugoslavia,
to
Caltech, for a total 9 at the moment. The student from Yugoslavia
is becoming
a real challenge. Additional students will be contacting me as
we get closer
to the start date or they know the dates for their finals. The
SURF schedule
is from June 14th thru August 20th and many of LIGO's members are acting
as
Mentors.
Completed 24 Expense Reports, some of which were extensive, involving
2 to 4
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.
Received
yesterday and late Tuesday, but not yet completed my audit, 13 Expense
Reports. These should be completed today, tomorrow at the latest,
barring
unexpected delays. I'm holding 1 expense report which requires
additional
information or is missing receipts from the traveler.
Worked on 4 Foreign Visitor trips which required extensively planning
and
coordination as well as the paper work involved for each. Three
(3) are
completed and one is pending final determination of flights and dates.
Had two
travelers going to the NSF Meetings rerouted by the airlines due to
bad weather
in Dallas. Dealt with the changes and details involved.
Prepared Travel/Vacation Itinerary for the Week of April 27th, 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.
