The Project Control Meeting
Agenda for Monday March 15, 1999 will be:
(Meeting time: 10:30 am Pacific Time)
Point your browser at this URL and you will get a raw index page which will lead you through a set of folders. The collection is not yet well organized. But it contains nearly 400 megabytes of gif, jpeg, and tif files, with a smaller number of eps and pdf files.
The most valuable files are gif and jpeg as these are web friendly and compatible with FrameMaker and Word and Powerpoint. The emphasis will be on high resolution images suitable for publication quality. Lower resolution images can be easily made from these (the reverse is not true). But, the gallery is slow to browse if you are not connected via ethernet to the network. FrameMaker files, or large pdf files are not useful original sources as these cannot be used to transfer images to other applications without considerable loss of resolution or color pallette. Charts from Excel or Applix spreadsheets are useful.
Over the next few weeks, I will work on the organization of the directories to make the system easier to use. Once it appears useful, a web page frontend will be added. Assume links to the gallery may be edited so do not assume links are stable enough to include in other documents yet.
Please send me pointers to graphics that you want to add to this gallery. Include a very short test descriptor for the collection or images you contribute.
When you receive requests from others for graphics to be used in publications and talks, please send pointers to me or Dave Beckett as well so that we can include them in this collection.

Weekly
Report Highlights
Livingston gate valve O-ring leak may indicate
O-ring pulling out
PSL Final Design Document
has been released.
General Items:
--------------
(Fred Raab)
We almost have the water system working OK. The reverse osmosis system
is
hooked up and flowing, but is still inefficient. Otto will get King
Soft to
fix it. We are awaiting the lab report approval to take down the no
drinking
signs.
Bake Oven:
----------
(K. Ryan)
LHO Vacuum Bake Oven A load #18 (consisting of BSC bellows S/Ns 019,
032 and
035) and load #19 (consisting of BSC bellows S/Ns 17, 18, and 111 along
with
misc. SS washers and a BSC system trolley link) were released this
week.
Load #20 (consisting of 10" optics FM01-A and 2ITM01-C and 3" optic
MCCM2K02-1 + misc. PAM screws) is presently half way through with its
vacuum
baking.
At present, load #21 is scheduled to begin Monday 3-15 and will likely
consist of two LOS support structures (newly arrived from being reworked
at
Brookfield Machine Inc.).
Seismic Isolation Installation:
-------------------------------
(C. Gray, H. Radkins)
Recent measurements, by the Vacuum Review Board, on mirrors exposed
to
Fluorel showed that their may be evidence of outgassing from Fluorel.
The
semiconductor industry which also employs Fluorel in their work treats
their
Fluorel items similarly to ours, but add a final step of a DI water
rinse. In
any case, we have decided to soak our Fluorel seats in DI water baths
and
letting them air dry in hopes of reducing this outgassing possibility.
Seats
were treated for both HAM 10 & BSC 8 work; we will be looking into
a company
to treat all Fluorel Seats for us in the future.
HAM 10 Work
The remainder of the stack for HAM10 will be installed
(Leg Element/masses,
Springs, Optics Table, and 500 lb payload)--thanks
to Betsy, Nergis, Lee,
Robert, Larry, Stan, and Hugh for all their help.
Setting of elevation and
level will be done at a later time because HAM
10 needs to have Air Bearing
for this step.
BSC Work
BSC 8 was closed up 3-3 and pumped down for leak
checks 3-4. There was one
leak in the Bellows on the Support Tubes but
a bit more torque on the bolts
stopped the leak. So, Phase Two installation
of BSC 8 is complete and next
week starting 2-16 the plenum will be vented
and Phase Three will begin. This
is the installation of the Isolation Stacks themselves, that is, the
Springs
and Leg Elements. Also, the counterweights will be installed. Then,
the
arrival of the Control Rack (expected 2-22) will provide actuation
control
and the Optics Table can be placed in nominal location.
The Actuation Stack was aligned 3-9 on BSC 4; and now awaits arrival
of
Actuation Stack components for further work. The Scissors Tables,
Airbearings, and Coarse Actuation Stage are expected at LHO 2-22.
Thanks to many who helped in the successful work
on BSC 8 and 4 including
but not limited to: Corey Gray, Larry Jones,
Robert Schofield, John Worden,
Dennis Coyne, Gary Sanders, Stan Whitcomb, Lee
Cardenas, Mike Fine, Betsy
Weaver, and Otto Matherny. The first one isn't
quite finished yet (Phase
Three) but there are only 14 after that! It will
be fun, thanks again.
Beam-Tube Bake Out:
-------------------
(M. Lubinski, M. Guenther, and W. Althouse)
Sun River has removed the blankets from the LVEA and mid station and
currently installing them for the X2 bake. We have completed
the bake of
ports X-6, 7, and 8. The RGA bake at X1-5 has been completed
and the post
bake measurements will begin this week. Ed
Watt has completed the
insulation work on X2. Congratulations
to Ed Watt, he has been awarded the
insulation contract for the Louisiana site and
will begin work in April.
Vacuum equipment: (Allen Sibley): As we were preparing for the RGA scan of the VE background we noticed an air signature in the scan. A leak check of the external system revealed no leak in the external components. The #2 GNB annulus space was not holding good pressure and it appeared that the gate seat was not holding. The VE manifold was at atmospheric pressure and the valve was sealing the "hard" way. We made the scan and sent it to Matt Smith for review. Other than the air leak the scan showed a clean system. The scan was taken with the system pressure at 2.2E-7torr, with only the one turbo and no ion pumps, so the leak was small. After venting the system to atmospheric pressure we cycled the valve to see if the cycling would cause it to seat. The leak rate after the cycling increased greatly. The annulus space would not pump below 600 torr (a very large leak!). It would appear that one and perhaps both o-rings have torn or pulled out of their groove. One note, this valve was baked by PSI in the closed position for both the vertex and manifold bakes. The system was then returned to atmospheric pressure by PSI. PSI subsequently cycled the valve to adjust the limit switches, but no leak check was made following this. In preparation for the RGA scan the valve was closed so that the vertex could be evacuated without the manifold gas load. The LVEA is now at 760 torr and activities scheduled in support of detector installation prevent immediate pumping of the system for further diagnosis. We are researching which other gate valves may also not have been cycled following bake out and potentially may exhibit this same problem.
Optics & Vacuum Labs: (Jonathan Kern): Lab water quality is steady at 15/16 meg-ohn in the Culligan system, and 18.3 at the optics cleaning station. The PSL table is accurately located and leveled, and the table enclosure is in place. Erection of the large Laser Safety Enclosure in underway. Fabricated a steel roll-around base for the air-bake oven, and installed several 208v receptacles in the lab areas so the oven could be located wherever the cleaning occurs. One more wipe-down of the labs is ongoing, and we'll probably transition the labs and LVEA to a "bootie" requirement next week. A milestone of sorts was established this week; I received a shipment from AirTech that was undamaged, 8 more worktables for the LVEA!!
Beam tube bakeout: This week we installed studs and hooks in the X arm to hang lights. We have studs down the length of the X arm and hooks along about 2/3 of the length of the X arm. Time was spent ordering equipment and parts. The insulation contractor plans to begin setting up on April 1. He will have two trailers of material show up on April 5 and. He expects two more trailers every week thereafter. He expects to be done May 31.
Anthony Rizzi:
40 m Interferometer (Bill Kells/Nergis Mavalvala)
---------------------------------------
Studies continue on comparison of PRM with
carrier resonant, and with side-bands resonant.
As might be anticipated the high gain carrier
resonant lock is dominated by fluctuations by the
least stable Recycling cavity mirror: South vertex.
We attempt to regulate S. vertex damping better.
A weekend was spent (Nergis, Dick, Keith) to
get the DAQ system up and running again (it had
not been exercised in some time). It is now set
for any extensive data running. A attempt was made
to also get the WFS digital servos going. However
this was not accomplished due to broken WFS detection
heads.

Interferometer sense/control (Zucker)
--------------------------------------
Near term site deliveries:
ISCT7 table enclosure arrived 3/1
ISCT7 table & legs arrived
3/10
ISCT7 optics/sensor assemblies/tooling shipped, due 3/12
ITM optical lever support tables due 3/22
ITM optical lever Tx/Rx heads & HW due 3/19
P. Fritschel and N. Mavalvala are currently at LHO to integrate and
test ISCT7 and complete testing on IOT7. E. Kruzel is
at LHO working on ISC assembly cleanrooms and field mods to the RM2k
optical lever.
S. Whitcomb reports from LHO a larger-than-anticipated
pumpout shift in
the optical lever readout of MMT3 . Our expectation
is based on
calculations of the distortion of the technical
foundation due to the
unbalanced atmospheric loading on the vacuum
equipment. We will use a
PEM tiltmeter installed near WHAM7 to try and
understand it better. A
fast cycle to rough vacuum and back may be requested
to test for hysteresis.
ISC installation (N. Mavalvala)
-------------------------------
ISCT7 arrived and has been moved to the assembly area behind
HAM12.
Wavefront sensor tuning is being set up in Optics lab.
Cabling to IOT7 is nearly complete.
IAS Initial Alignment (K. Mason, M. MacInnis)
----------------------------------------------
A two sided parallel optical flat was ordered which will enable
alignment of the 2k beamsplitter through chamber access doors.
#MZ note: the realization that
"removable" spools are not
_really_ removable has us
doing some scrambling to find
alternate aligment shots.
Some more special tooling will
probably be needed in the
end; but it looks like we
should be able to do it.
Completed a plan for the replacement of sensor actuators in MMT3 and
RM.
A copy of the plan can be found on the Caltech ftp site
/pub/kmason/D990024-02-D.pdf.
Myron has assembled and tested optical levers for the y-arm folding
mirror, ITMy(2k), and ITMy(4k).
#MZ Optical lever diode lasers
in work for shipment to sites
have had their wings clipped
to comply with Class IIIa safety
requirements per site directive.
The two currently
installed at LHO have also
been certified IIIa.
ISC optical levers & ISC table fab (Matt Smith)
-----------------------------------------------
The support table, legs, and support structure are through machining
and
into paint. They all should be done Friday and shipped on Monday.
I
will visit the vendor tomorrow morning for inspection. I provided Larry
Jones with the hole locations on the floor for the Y arm. There
were
some minor inteferences for the first layout. We repositioned
the holes
to eliminate the problem. The cable trays will need to be shifted
about
an inch. Rich McCarthy is working this issue.
95 % of the purchase orders have been placed for the balance of the
ISC
tables.
Reworked a riser block for the optical lever to the 2KRM to allow
further rotation of the mirror for the laser and shipped it to Hanford.
The new sideplate and tube should be delivered tomorrow.
ISC supervisory control code development (Ed Daw)
-------------------------------------------------
This week I compiled a preliminary list of outstanding
software tasks for ISC, which was distributed to the
ISC group. I started writing documentation for my
ASC ddcu (Digital Data Collection Unit) code, which
will be available on the web (together with listings)
through the MIT LIGO web site.

--------------------------------------------
Prestabilized Laser -- Peter King
--------------------------------------------
- A batch of current design pre-modecleaner bodies has arrived and are
about to be cleaned and baked. The fabrication of a new pre-modecleaner
will test a new piezo-electric transducer, which provides 4.5 microns
of
travel for 150 V.
Other pieces for fabricating the pre-modecleaner
should be delivered
from CES by 03/22.
- The new 80 MHz VCO has been tested in the CDS workshop. It will
be
tested in the PSL Lab, prior to be installed with the LLO PSL.
- The PSL Final Design Document has been released.
It is registered with
the DCC with the document number T990025-00-D.

------------------------------------------------
2K Installation -
The OSEM problem has delayed the installation of the SOSs. THe
last mode
cleaner mirror, MC2, is in the oven baking.
50 wire standoffs have been fabricated; 10 have been sent to Hanford
for
use on the 2K optics. 40 have been sent to Yehuda for baking
for LLO.
Analyzed the RFAM of the second EOM at the modulation frequency of 29.486
MHz. By adjusting the orientation of the polarizer, the RFAM was made
as
low as 7e-7 in intensity. Temperature fluctuations vary the RFAM to
as high as 2.5e-5 overnight.
4K Fabrication -
SOS manufacture:
The Al stiffener plate and upper safety screw holder are done. One
set of
Al parts (the brackets that hold the under-mirror safety screws) are
just
being started. The safety screws themselves are at CIT for baking.
The
tower bases, top bar, and wire clamps are done. Wire standoffs and
guide
rods are done and at CIT (wire standoffs) or LHO (guide rods). We'll
start
on magnet standoffs in about a week, I imagine.
The OSEM plates are being sent to the wire edm shop today. The uprights
are
almost done---will go to the wire edm shop next week. When these parts
come
back, we need to put the set-screw holes in and assemble to check for
fit.
Then we can ship to LLO. We need to check the parts count of silver-plated
screws. We have considerable: some will be shipped from here for cleaning;
others are at LHO and already clean
Core Optics Procurement and Metrology -- GariLynn Billingsley
-------------------------------------------------------------
Gary, Gari and Michael met with Alan Rice to look
into the possibility
of moving the IR metrology lab. The move
is not impossible, but the
schedule probably is. We have committed
to higher quality measurements
for the LA4K optics. One part in reaching
this goal is a thermally and
vibrationally stable environment. While
we believe that the CRS meets
those requirements, we do not believe that we
can be moved in time to
deliver the optics in June with higher quality
phase maps. We are
currently thinking of ways in which Lauritsen
can be made to work in the
interim without dumping a ton of money into the
facility.
The 2nd 2KITM for Hanford (2ITM04) has been measured and handed off
for
scatter characterization. The normal incidence data has been
taken for
the 2nd FM (FM02), it remains to take the data at 45 degrees.
Taking
this data at 45 degrees is proving much more difficult this time than
for FM01. This may be due to thermal gradients, the room is the
warmest
it has been, almost five degrees C higher than when we moved in.
Core Optics Coatings -- Helena Armandula
--------------------------------------------------
CO2 cleaning: A 3" substrate was cleaned following Ligo cleaning
procedures, passed the "steam test". A scatter scan was performed.
The
surface showed some scatter points. The part was then drag wiped and
scanned again. Most scatter points disappeared. The substrate was then
blasted for 90 seconds with CO2. Substrate and CO2 gun were grounded.
A
subsequent scan showed a new spike. Cleaned the substrate once more
with
CO2. The next scan showed the same spike plus an extra one. To be certain
that we were not damaging the surface we drag wiped the surface several
times, a new scan was taken, the added spikes disappeared, the surface
showed the original footprint. The prolonged blast of CO2 did not damage
the surface. Process control has to be improved to ensure efficiency
with
the cleaning.
We'll run more test next week concentrating in the cleaning procedure.
Core Optics Support -- Michael Smith
------------------------------------
BEAM-DUMPS
Drawings for the cavity beam dump have been sent out for bid on production
fabrication. We expect to begin production next week.

COS
viewports. Uncoated windows for the APS viewport s have been ordered
from
CVI and will be sent to REO for 99.9% AR coatings. The conflats have
been
ordered from Varian, and this appears to be the long lead time item.

Seismic Design (Mike Fine)
--------------------------------------
1. Electronics Rack:
Another noise source was detected on the AC lines during initial testing.
Through diagnostics Hytec was able to identify the source and derive
an
appropriate fix that eliminated a substantial amount of noise
from the AC lines. Hytec installed the appropriate cables to drive
the W
actuators and were able to move all four W actuators simultaneously.
They
finished connecting all of the cables to the BSC prototype and tried
bringing the system on-line.
2. Coarse Actuator Stages:
Hand precision has finished with all of the air bearing driven mounting
plates and need to complete the installation of the helicoils. Hytec
will then need to have the spacer blocks made prior to final assembly
for
shipment.

Optical Contamination (Daqun Li)
--------------------------------
Vacuum cycling cavity two containing viton pieces has not shown any
effect so far on losses measured with ringdown and mode-spacing
techniques.
After being treated with the recently established DI water washing
procedure, the second set of fresh viton seats has been loaded into
cavity one with a few chopped pieces even placed inside the cavity
glass spacer for direct mirror viewing. The DI water washing procedure
for viton, brought up by Stan and Larry Jones, involves 10-minute DI
water soaking, clean lens tissue wiping, and 24-hr air drying. This
cavity is currently under vacuum pumping. Relocking the cavity for
light illumination will take place early next week.
Revised the manuscript of contamination studies and the revised version
has been sent to the Editorial Board sponsor for internal distribution.

tables to contain the logfile data from
the LDAS
API's.
(PSE) continued work on the frame API. began to incorporate
the functionality
of the frameAPI.so and genericAPI.so
into the
frameAPI.tcl
Bruce Sears:
* Working on the definition of Inter-API communications in LDAS processes
Met several times with Kent Blackburn, Phil Ehrens,
Dave Farnham,
and Ed Maros to discuss this and clarify the TBDs
in implementing
inter-API communications. Wrote several strawman
examples which
are still evolving.
* Maintenance on the Hanford electronic log software (ilog).
Standard work on minor bug fixes.
Stuart: Developing a proposal for a data archive to storing several weeks of raw data directly at the interferometer sites.
General ComputingMIT:
Hanford:
Nothing to report
Livingston:
Finalized the switch over on the e-mail accounts. All of the local users
at the Observatory are now receiving e-mail locally. The address for
the
users in livingston is name@ligo-la.caltech.edu. Their e-mail will
is
being forwarded to them from CIT. Next is to get the WEB services moved
permanantly to the Observatory.
CIT:
Barbara K. reloaded NT Workstation on Paul Kabot's new machine.
Finished up the last of the backlog of web site changes.Backed up the
DCC database.
Suresh has ugraded another machine to Solaris 2.6. Only a few more to
go
and all of the machines will be upgraded. Performed multiple computer
switches and software upgrades on them. Currently, installing the print
drivers on the new print server which we hope to install this next
week.
Also, working on replacing the hardware on a Sparc 30 that has crashed,
Stuart A. is working on that problem with Suresh.
Suresh and Ed Maros have installed a tape unit on spica to assist in
backing up the unit until the tape robot arrives.
Monday we had to put the old ligo server back on-line while we made
some
changes on the new server to eliminate some e-mail problems. The
new
server was put back on-line monday evening and
appears to be working
fine. The problem appears to have been a DNS
conflict with the secondary
DNS servers.
We have addressed a couple of security issues. Also, we are in the
process of purchasing ssh for the PCs.
A number of server units and network items have been or are being
ordered at this time to accommodate the increased need for printing/mail/web
services.
Then the usual of setting up new accounts, cleaning out old accounts,
software installations, burning CD's, e-mail changes are still going
on.
The network appears to be much more stable. The problems resolved:
1. A couple of bad transceiver boxes have been bypassed. These appear
to have
been the big culprits.
2. A loose cable on a transceiver, I did not know about, has been reseated.
3. Network/cable redundancy on a gateway machine which caused some
pathway
conflicts has been removed.
4. A number of people running large programs across the old network.
Some have
been moved to the new network. Ones moving large amounts of data on
the old
network have been asked to do it after hours.
5. Someone unplugged a cable not knowing it would bring down the network
in the
basement. I replaced the jumper and let everyone know about it.
6. Still have a lot of traffic going through a small pipe on the Caltech
backbone. The ITS group is looking into getting us another way out.

Irene Baldon
Worked on preparing the paper work for various new trips taken recently (23 Purchase Requisitions and 13 Advance Requests). There are 12 additional new trips pending completion of travel arrangements and the necessary paperwork. Completed 32 Expense Reports. Some of these were still not taped or completed by the Traveler and required more time for completion. Received in the mail (late March 9th, yesterday March 10th and this morning already) 14 new Expense Reports. These will be completed today (tomorrow by the latest) and sent out for approval and then forwarded to Travel Audit. I still have 1 expense report that is pending additional information and/or receipts before I can complete it. I continue to experience an influx of expense and advance checks which requires recording, filing and distribution to the individual traveler as a result of the increased number of Expense Reports being processed.
There are still 12 - 1998 Travel folders to be cleared and sent to DCC for permanent storage. These are folders containing Visitors, Job Applicants, Consultants, and various conferences. While pulling the 1998 individual files I found a number of trips not completed with the submission of an expense report. I have been contacting these individuals as time permits. Please submit your receipts if you still have an outstanding 1998 trip. I have only received a couple of 1998 expense reports. Please send me you receipts as soon as possible.
Prepared Travel/Vacation Itinerary for the Week of March 9th, 1999.
Performed miscellaneous duties as requested by various members of the LIGO Project here at Caltech, as well as for members of the staffs of each of the two (2) sites. Also worked on a number of problem issues which required a portion of my time.
Rita Torres
For I. Petrac did change order No. 4 to Galli & Morelli, then distributed after signature. Did edits to various MOUs. For E. Jasnow did PC293660 with Pacific Industrial Insulation for Furnishing and Installation of Beam Tube Insulation at Livingston. Obtained 10 copies of this contract, then sent three to Pacific for signature, distributed the rest.
Met with Safety committee to follow up on last week's discussion on prescription laser glasses. Helped I. Baldon copy some travel documents. Got a chance to purge duplicate, or otherwise useless, electronic files.
INFORMATION
Take care when folding back the partition in the SCR! The projection screen in the small conference room gets wrinkled, and a metal part bent, when these are caught in the partition.
Elizabeth K. Wood
Reimbursed petty cash fund.
Reconciled credit card accounts for Gary and Liz.
Began preparations from my end for the NSF site review at Livingston. Talked to Vic Cook about who from the NSB should be invited and who will be on the NSF Review Panel.
Contacted various people for tours for the Physics Grad Admits Visiting Day March 25 and 26.
Dealt with personnel and payroll issues.
At Rita’s suggestion, she and I looked at the projection screen in the little science conference room. When people open the partition between the two rooms, all too frequently they don’t raise the small SCR projection screen. As a result, the screen is getting scrunched, and one of the ceiling doors does not close properly because it has been bent. PLEASE raise the projection screen in the little SCR before opening the partitions. If the projection screen continues to be battered in this fashion, it is not clear yet what part(s) will need to be repaired or replaced. The screen is also receiving more and more creases and becoming less of a flat projection surface.
