The Project Control Meeting
Agenda for Monday October 19, 1998 will be:
(Meeting time: 10:30 am Pacific Time)
NSF REVIEW DRY RUN
Bake Oven:
----------
(K. Ryan)
This week I installed the Nitrogen vent system. I am in
the process of comparing the pre-vent scan to the post-vent scan
data. This will demonstrate what is contained in the Nitrogen vent
gas and what it contributes to the rga background. We will review this
data and, if the post bake background is acceptable, will prepare to
bake two of the eleven HAM support tube bellows.
Seismic Isolation Installation:
-------------------------------
(C. Gray, H. Radkins)
HAM7 INSTALLATION
HAM7 was closed up for pump down last week. A preliminary leak test
showed that there were two leaks on the "northern" pair of Bellows
(around the large conflats). One leak was remedied by tightening down
the conflat a little more. The other leak was not fixable. This Bellows
will be re-installed today (10/15), so that it can be re-checked for
a leak soon. The elec. feedthroughs were also checked for leaks (4
on
HAM7 & 1 on HAM 8 and HAM9)--they were ok.
4k HAMs
Piers for the 4k HAMS are currently being positioned and torqued down
in preparation for grouting which will commence next Mon. (10/19).
BSC Piers
All holes for BSC piers have been located. Apollo will finish drilling
and installing anchor bolts.
Items received this week:
* 4 Scissors Tables
* 4 Air Bearings
* 12 Bellows** (These Bellows need to be cleaned and Kyle
has been
consulted about baking these in the Vacuum Bake chamber)
* Pallet of BSC fixtures
Outlook for "immediate future":
Grouting of all 4k HAM Piers
HAM7--Install Actuation stacks and X-beams
HAM9--Install Support Tubes, Support Table, and Bellows for leak test
HYTEC, Los Alamos NM:
The Stack Spring Positioning Jigs have been tested
for form and
fit as have the Leg Element Alignment Pins. These items have been sent
along with an in-vacuum spacer washer (and received) to CIT (Y.
Kommemi) for the clean and bake process. The last items of the HAM
assembly bolts kits were packed up and sent to LHO. The Bellows
maintenance fixture (BSC) was installed and modifications are being
reveiwed. This fixture allows the removal of a bellows without removing
other parts of the system; it worked fine but modifications will allow
faster, cleaner, and easier use.
W.K.Miller's BSC Assembly Procedure has been reveiwed and redlined
by
HYTEC personnel and H.Radkins; rewrite is slated for next week. The
HAM drawings are approaching final revision with many Engineering
Change Requests generated and in various state of completion.
A faulty motor was replaced and coarse x-y translation testing
continued; however, no complex motions have been attempted yet. The
Fine-x translation PZTs have been calabrated (really a setting of the
electronics' offset), installed, and moved. There seems to be
electronic noise in the PZT that settles down after a time; this has
yet to be sourced out.
Otherwise, the PZTs worked fine. Calibrated movement and measurement
at the Optics Table is planned for 10/15&16.
Optics & Lasers:
----------------
(D. Cook)
We have officially transitioned the site into the "Laser Safe"
condition under the requirements of the Standard Operating Procedure
LIGO 980046-B-W. This transition included filing for a site "work
permit",filling all the SOP requirements which included walking through
the LIGO M980048-B-W procedural checklist with Otto Matherny. The PSL
is back on line once again. Thanks, to all who helped to iron out the
details.
We have had some of our Laser Safety Glasses leave the Hanford site.
Please be sure to place them back in the holders daily when you are
through using them. We have a limited supply and they are expensive.
We need to maintain a minimal amount to cover visitors,tours etc. I
would like to be able to make them easily accessible and not have to
check them in and out to each individual.
Computing Systems:
------------------
(C. Patton)
The Passport Credit Card training session went well. The account
managers are eagerly awaiting their credit cards.
The new T1 line is tentatively scheduled to be available around Oct.
26. This is dependent on travel schedules for Larry Wallace and
the
contact at PNNL. The first step is to get the Domain Name Service
started and then to program the routers both here at LHO and at PNNL.
The security procedures and www/email server also have to be set up.
We
will start slowly with only a couple computers transfered to start,
and
will keep the ISDN line as a back-up for at least a month after
transfering to the T1 line.
Beam-Tube Bake Out:
-------------------
(M. Lubinski, M. Guenther, and W. Althouse)
The "post bake RGA" has been set up at port Y2-6 and Rai has taken
measurements on the beam tube. Conclusion after
analysis of the data is
that the bake out of Y2 module is complete.
We are baking out the RGA
again to achieve a more sensitive base line measurement on the Y2
module. We have removed the RGA from port Y2-5 and a Cryopump from
Y2-7, those ports are being baked out now. The Cryopump cold plates
have a residue on them and the Cryopump from port Y2-6 will have an
analysis done on its residue to determine the contents and possible
source.
Sun River is currently removing blankets from the Y end station and
positioning them in the LVEA. The DC cables have been disconnected
from
the Tube and power supplies and will be move later this week.
Contacts with a local supplier of a high volume low conductivity water
system (similar to the upgraded system used in Hanford) have been made.
We
are obtaining quotes and identifying the best place to locate it within
the
building. We took advantage of Parson's architect being here this week
to
discuss various location options that satisfy building code requirements.
We are continuing to procure support equipment. Some delays with placing
purchase orders for critical items have been encountered and we have
asked
for Ed Jasnow's help in expediting these items. We received three HP3561
spectrum analyzers from Kiesler Air Force Base courtesy of Ed Chargois.
(These are single channel, low functionality spectrum analyzers, but
nevertheless nice to have. He also found us a Tektronix cable tester
which
will be very useful.)
Quotes for cubicles and partitions for additional open office space
have
been received. We have also obtained quotes from 3 local vendors regarding
the purchase of a photocopier.
Larry Wallace arrived and worked Livingston staff to set up the mail
server
here. There is still some work to do, both here and at Caltech to make
the
process run. We still need some hardware to be delivered and some further
software modifications before we can dial in to this site.
We began assembly of the weather stations for the corner and end stations.
This has raised several implementation issues with respect to making
a
robust installation of this equipment. We are considering various solutions
to mount, power and read out this equipment that will be durable.
Rich Riesen is at LHO this week to participate in the seismic installation
and to get feedback on the control room layout so that we can begin
to
procure similar items for here.
Livingston Vacuum Equipment (Allen Sibley)
The x arm has been successfully vented with the PSI clean air compressors.
Venting duration was approx. 100 hrs using only the end station compressors
for the majority of the time.
GNB has arrived on site to begin valve repair. The x arm mid station
valve
has been removed and inspected. The only problems found are two sheared
off
stops and two damaged wheels. These are relative minor repairs.
PSI has cut
the access hole in the tube and will install the stub out today.
Access to
the valve appears good. GNB is waiting for parts to complete the mid
point
valve repair and it should be back in service in about 1-2 weeks. In
the
mean time they are working on the other x arm valves.
(GHS note: Some very nice pictures can be found at
ftp://ligo.caltech.edu/pub/Livingston/GNB/
courtesy of Jon Kern, especially #19 which clearly shows the sheared stops.)
Beam Tube (Larry Jones)
a. Livingston Installation
CBI has completed both the Y1 module accum and the global calibration
and
posted the data on the LIGO net. Cracking patterns were completed except
for
NO and CO2. Because of certain problems with RGA performance on Y1,
they are
moving to a second RGA on another pump port and will repeat all tests
for
backup data. They hope to finish by Saturday evening.

of the existing vault by at least 2 ft on all sides to allow for
a 90 degree bends to PVC conduit on each side. At least a 4 ft of
straight run will be added to conduit to bring it to about the
grade. The fiber optic contractor need to allow two more 90 degree
bends
on each run.
>
> 3.Rain leakage at OBS/LVEA. David Dai, Parsons
architect, has been
at the site. He has inspected the leak areas. He has discussed his
findings
with site personnel and me. Then he has met with representatives from
Hensel
Phelps (general contractor), roofing sub-contractor and wall pannel
sub-contractor. He has dicussed and indicated the non-compliance areas
to
them. He has discussed and proposed a method for fixing the leakage.
He is
going to prepare and submit a formal report up-on his return.
ed, Gerry and
I will discuss and resolve the contractual matters, up-on the receipt
of the
report.
Next week I will be at the Hanford site, in support of SEI
installation.
Hanford Construction (Otto Matherny)
Levernier
Levernier submitted their final invoice and a certified statement that
all
the subcontractors and suppliers were paid.
OTHER ITEMS
Water modification Contract
The water line to the Staging Building is complete. The foundation
for the
new tank and the permanent connection to the sprinkler system is also
complete.
Staging Building
George Grant Construction submitted four RFIs. The questions
will be
answered by Dillman-Luvaas Architects.
Livingston Construction (Gerry Stapfer)
A review of the building water proving (trying to find the root cause
of our
persistent leakage problem) indicated that the problem appears to be
related
primarily to the expansion joints. Several details of these flexible
joints
either used improper components or were not installed in accordance
with the
manufacturer's recommendation.
Parsons' architectural specialist, David Dai, was on site, together
with a
representative of Hensel Phelps, the roofing subcontractor and the
siding
subcontractor. Hensel Phelps acknowledged their nonconformance but
did not
have a satisfactory solution for the problem. Mr. Dai proposed a conceptual
solution and Parsons is pursuing it in more detail.

DETECTOR GROUP -- Whitcomb/Shoemaker
(WBS 1.2, 1.3)
----------------------------------------------------
40m Prototype (Nergis Mavalvala)
--------------------------------
The two experiments we reported on last week were continued
this week with promising, though sometimes ambiguous, results.
1) Power budget/ifo losses/matching:
In an attempt to measure the mode matching into the arm cavities,
we offset the frequency of the RF PM sidebands so that one of the
SB resonates at the TEM 20/02/11 frequency in the arm cavity.
Measurements of the transmitted power at the SB frequency and at
twice the SB frequency had a predictable qualitative behavior,
but it has been hard to get a consistent quantitative measurement.
Among the effects that complicate these measurements is an observed
splitting between the TEM10 and TEM01 modes (due to astigmatism
in the optics, we believe). We are now pursuing a different approach
which is to measure the 2*freq_SB term at the antisymmetric port
when the simple Michelson is locked with one arm cavity. In this
case, mode mismatch of the SB is irrelevant, since the SB is not
resonant in the arm cavity, so the SB acts as constant against
which the carrier beats. If there were large mismatch, the overlap
between the carrier cavity mode and the SB mode would be small and
we calculate this to be a measureable effect. Preliminary numbers
point to fairly good mode matching.
2) Wavefront sensing closed loop control
We were able to control the orientation of the East arm cavity
end mirror using wavefront sensor signals. The servo filter was
implemented digitally and we bypassed the orientation controller.
We also used an existing relay switch module to deactivate the
local orientation controls and kick in the WFS controls after
longitudinal lock is acquired. This switching is not very
"graceful" at present and there is some question of how the full
ifo will tolerate the switching. We also ran into some secondary
yaw resonances around 20 Hz (excited due to the increased bandwidth
of the WFS controls compared to the optical lever controls),
which had to be notched out. The WFS controls were tweaked till
we had high DC gain and a bandwidth of over 20 Hz, i.e good
suppression of 1 Hz oscillation. We are now replicating the
hardware and software for the South end orientation controls.

LSC control code development (Daw, Fritschel)
---------------------------------------------
I have created a list of LSC channels that will be
passed between the DAQ/GDS reflective memory and
the reflective memory loops for the X and Y arms.
I have found all the pieces necessary to install
and use VxWorks at MIT, and issued a PO to Wind River.
ASC wavefront sensing (Mavalvala)
----------------------------------
The WFS sensing matrix for the mode cleaner was transfromed into
the input beam misalignment basis (vs. cavity mirror misalignment).
Data on the location of the input beam steering mirrors was also
received. Gain of the controller can now be calculated.
All optics postion data for calculation of Guoy phase telescopes for
the 2k and 4k ifos is now assembled, that's the next "to do".
ASC Design and Fabrication (K.Mason, M.McInnis)
---------------------------------------------------
An alignment support stand has been designed which bridges over pipe
and
cable trays while doing an initial alignment. A movable saddle on the
stand allows you to position the theodolite over the initial alignment
monuments.
Trials with the autocollimator mounted to the theodolite have stopped
due to problems with the autocollimator. Peter Fritschel is chasing
the
problem with Newport.
An order was placed for an additional theodolite for Livingston,
a
tripod to use with the support stand, and calibration training for
the
Brunson square and Sokkia Field Station.
The enclosure for IOT7 is almost complete and is still scheduled to
be
shipped on October 23rd.
ASC Design and Fabrication (M. Smith)
---------------------------------------------------
Continuing to work out the optical lever support bridges (TM type
supports). Quotes have not come back for the optical lever wedges
(BSC
type supports).

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)
--------------------------------------------
Lightwave 10W laser contract -- Jordan Camp
---------------------------------------------
We expect to receive the first option 10W laser around the end
of Oct. It will support 100 ft cooling lines, an enhancement to
the initial design that we have requested.
Prestabilized Laser -- Peter King
--------------------------------------------
- The 2k IFO 10-W laser is back on-line, operating under a revised SOP,
LIGO -M980046-B-W.
- Currently the optical train to the frequency shifter is being laid
out.
Input/Output Optics -- Dave Reitze, UF
-----------------------------------------
Dave will be at Hanford next Thursday for ~ two weeks. Qi-Ze will
arrive
November 1.
Installation-
Not much to report. Some additional parts are being done in the shop
and
some have been sent out to Yehuda and to Doug Cooke.
Optics Characterization -
The UF group has developed two conceptual designs of ways to measure
the
radius of curvature of the MMT3 (nominally 26 m). The first method
involves
establishing a poorly-coupled, relatively high-finesse, approximately
4
m-long cavity with MMT3 and a plane mirror. Sweeping the laser through
the
free spectral range of the cavity will give resonances of the TEM_mn
modes;
when one of the higher-order modes (n+m=6, say) is coincident with
the
TEM_00 modes, the g factor can be determined; from this and the cavity
length the radius can be calculated. Different positions on the
MMT3 can
be sampled. We estimate that this will give the RC to better
than 0.1%
The second method involves a interferometric measurement where two beams
from the same laser are reflected from the curved mirror and brought
into
interference with some shear. By moving both beams transversely across
MMT3, the optical path difference will be controlled by the sag
of MMT3,
and the RC can be extracted from a measurement of the fringe shift.
Mode Matching Measurement -
Made a position sensor and electronics for the alignment of the beam
to
the dithering lens. The procedure of the alignment turns out to be
a
difficult task.
A method involving dithering the lens and using lock-in detection of
the
beam on a position sensor is under development to overcome this problem;
i.e., to try to align the optical axis of the lens and the translation
motion exactly to the propagation axis of the beam.
Core Optics Procurement and Metrology -- GariLynn Billingsley
-------------------------------------------------------------
We are gathering calibration data for the IR interferometer. The
goal is
to get good characterization of test flat "C". This is a coated
test flat
which will allow us to take data of reasonable contrast with Beamsplitters,
as well as highly reflective optics. We have great difficulty
getting
repeatable measurements with C, the reason that this is more difficult
than
with the uncoated flats is not yet known.
Our typical night-time repeatability with C is on the order of 0.4nm
for
successive measurements and 1 nm for non successive measurements.
Day
time measurements are slightly worse at .5 and 1.2 respectively.
"Repeatability" is defined as the difference between identical
measurements. The setup is very sensitive to vibration; only
20% of the
data we get are marginally useful, the rest are deleted. Good
repeatability is around 0.2 nm rms for 4 or 5 successive measurments,
this
has been achieved with flat C once so far. We assume right now
that it was
just a very quiet moment in the building.
We are now attempting to beat down the noise with statistics, we are
hoping
that enough averages, at the same temperature, with a perfect null
cavity,
will give us a good picture of flat C. We will compare these
results to
our one good data run and hope for agreement.
Core Optics Coatings -- Helena Armandula
--------------------------------------------------
REO Contract - COC's coatings: BS05 has been received and will be coated
next week. In conjunction with REO personnel, their cleaning and inspection
procedures have been reviewed, in paper. We tested in the OTF lab.
the
Caltech developed procedures on a beamsplitter, with good results.
We are
prepared to implement this procedure at REO if their improvements do
not
prove satisfactory. All the elements needed will be available at REO.
Finished the coating inspection of the UFL optics. Most optics were
found to
be acceptable, except 4 mirrors of a lot of 5, coated on both sides,
that
showed noticeable coating discoloration. This will be discussed during
my
visit to REO.
Checked 4 coated RM's under a dark field microscope, they looked very
good.
Also looked at two more coated ETM's, also, very few defect points
were seen.
Core Optics Support -- Michael Smith
------------------------------------
BEAM-DUMPS:
Ara has released some parts of the redesigned generic beam-dump to
the
shop, and is completing the remainder of the design.
A concept design has been developed for the specialty beam-dump which
will
be incorporated into the elliptical baffle mounted to the ITM LOS structure.
ITM BAFFLES:
Angel is completing the layout of the ITM-y baffle. The baffle at the
mid
station, located beyond the 2K ETM and facing toward the 4K ETM, remains
to
be designed.
ETM and PO Telescope-
Mike S. and Ken M. reviewed the final design of the PO and ETM telescopes.
CC Development is making recommended changes to the PO and ETM telescope
designs, prior to detailing. The changes will be reviewed at CIT on
10/17/98. Mike S. reviewed the tolerance requirements of the PO and
ETM
telescope with Optics 1. The optical and mechanical tolerance
specifications for the PO telescope will be relaxed as a result
of the
tolerance analysis. The results of the tolerance analysis for the ETM
are
still being studied.
MOCK-UP
The mounting structure for the BSC SEI table was completed, and the
SEI
table is suspended. Janeen is interested in mounting a prototype LOS
with
an aluminum COC. This will enable simulation the APS beam for alignment
purposes.
OPTICAL LEVER BEAMS
Mike S. and Angel have completed verification of the ISC optical lever
beam
paths. All proposed optical lever paths are satisfactory, except for
the
MMT3 and the 4K RM paths. The MMT3 mirror must be hung with the heavy
side
of the wedge down, and the end cover of HAM7/HAM1 must be rotated 180
degrees, so that the center optical viewport is below the centerline
of the
HAM chamber. The side cover of HAM2 must also be rotated 180 degrees,
so
that the optical windows are below the centerline of the HAM chamber.
PO MIRROR
Ken M. is working on the design of the pick-off mirrors, and assisting
in
reviewing the design of the PO and ETM telescopes. Mike S. has generated
a
list of PO beam heights and pitch and yaw angles for the PO mirrors.
CONICAL BAFFLE
Craig C. is working on the design of the conical baffles which are
mounted
in front of the cryopump.
STEERING MIRROR
A quotation has been received from Dynamic Light for the 2 in. steering
mirrors for the PO beam optical train.
COS FINAL DESIGN REVIEW
Mike S. has begun to gather information for the FDR. Full effort will
be
devoted to the FDR in about a week, after CC Development has completed
the
design of the PO and ETM telescopes.

Seismic Design (Mike Fine)
--------------------------------------
1. Air Bearing Tests:
Specialty Components is shipping four new air bearings to Hytec in
an
attempt to correct the stiction problem Hytec has experienced on the
BSC. Hytec will trade out the old ones and ship them back to SC for
inspection.
2. Fine Actuation System Tests:
Tests on all 4 PZT channels were performed at Hytec last week in
preparation for system tests (end of this week). The static gains and
linearity of the 4 channels were measured and compared: over 180 micron
range, the largest difference between any 2 of the 4 channels in 2.5
micron (3 of the 4 are within 0.8 micron of each other, the 4th one
is
about 2 microns off). Linearity is excellent (better than measurement
accuracy or 0.1 micron). Hytec will try to repeat this type of measurements
in dynamic operation (phase synchronization) next week, then perform
static
tests on the BSC.

1. LOS Alignment Fixtures:
Superior Jig delivered two alignment fixtures to CIT and two
lift tables. The hardware are being cleaned by Yehuda before
being shipped out to sites.

Detector Systems Engineering -- D. Shoemaker/D Coyne
(WBS 1.2.1.1.9)
---------------------------------------------------------
Global Diagnostics System (Daniel Sigg)
--------------------------------------
No report this week.
Physics Environment Monitor (Alex Marin)
-------------------------------------------
A partial shipment of the Siesmometers are due to be shipped the end
of
this month. We will be getting at least 3 and maybe 5 out of
the 8
ordered.
Optical Contamination (Daqun Li)
--------------------------------
The after-venting ringdown and mode spacing data for cavity 2 containing
air baked steel still suggest 141 ppm in total cavity loss and ~ 9
ppm in
absorption loss, a significant increase since the end of the viton
run.
Higher mode ringdown measurements indicate that the loss
is still not localized. A record survey for this cavity shows
that at each
test stage, all the three factors (storage time, frequency shift regarding
to same amount of change in stored power, and the cavity throughput)
observe
increased losses, suggesting that unlikely there is a measurement error
throughout the whole testing process. Light exposure period has not
had an
effect on losses for this cavity.
Automating the Loss Scanner is going well. The PC communicates
well with
the stepper motor controller and the encoder readout. A subroutine
written
in Labview automatically drives the table to a particular location
within
+/- 0.01 mm in both X and Y directions. Automatic scanning programming
is still going.

Attended the 1998 PMI convention in Long Beach. Researched the latest product development for Welcom's Open Plan Software. Newly introduced software by the name of "Spider" which allows increased ability for Web based reporting and updating of Open Plan projects.
A modification is being issued to Woodrow Wilson Construction in the amount of $25,000 for repairs made to service roads as a result of heavty rainfall.
Meetings with Hensel Phelps and an architect from Parsons have resulted in the design of a solution for the leaks in the LVEA at Livingston. The final design is expected next week, and the contractor will commence implementation of that design.
The FY 1999 Operations Work Plan is being reworked. The end-of-August Quarterly Report was sent to NSF and to the NSF Review committee this week. I appreciate the contributions made.

LIGO QA coordinated a "mini" TRB to consider a proposal to modify the valve repair plan by not cutting into the beam tube for installing a "man way" and to perform valve body inspections/repairs and adjustments "externally". After discussion of the "risk" trades and concerns, it was decided to continue the man way installation and valve repair as originally planned. This TRB did identify an issue which was deferred for discussion to another time, that a man way may be requred in the Y-arm for mid-station valve acceptance.
As of late Tuesday, the X-arm beam tube hole was cut w/o problem and
the baffle found to be clear of the hole. Man way flange assembly installation
should be complete this week.
1.4.3 Systems Engineering

Control & Monitoring (CM) System section of
Maintenance
Plan was sent to Rolf Bork for Review and Comment.
Prepared draft of Integrated Sensing/Control System
(ISC)
fault trees and e-mailed it to Mike Zucker, Cognizant
Scientist, at MIT for review. Fault tree structure
assumed
that CCD cameras, used for beam viewing, and the
optical lever
system, used for initial alignment only, were non-essential
for the collection of science data in the normal
operating
mode.
SEISMIC TABLE BALANCE WEIGHTS:
Weights have been ordered and delivery of first
1000#
(quantity required for first two HAM chambers)
is
scheduled for 11/2/98, @ Hanford Observatory. Balance
will be delivery of 2000# every two weeks till
10,000# is in house. Approximately 1/3 of the lot
will
go to the Livingston Observatory.
ELEVATED PLATFORMS:
The purchased, extended top, 3 step platform appears
to
be acceptable. Four more units are being ordered
with
delivery to the Hanford Site expected by 11/6/98.
X-BEAM & Y-BEAM SPOOL BAFFLES:
Work on detail drawings is just starting.
OPTOMECHANICAL INTEGRATED LAYOUTS:
The plan & elevation views of the LVEA in Hanford
were
released (pdf file) last week.
1.4.3.1 Systems Engineering & Integration (AL, CC, JK, DC)
1.4.3.3 Modeling & Data Analysis (KB/HY/AL)
(MODELING)
multi mode implementation: (BB)
Various changes that we recently made on single mode
code
in order to take care of Michelson asymmetry have
been
incorporated in multi-mode code.
Higher order mirror-rotation calculations upto m+n=3
passed
various tests.
The modifications necessary to include multi-mode
calculations
in the existing summation cavity (needed to have
a fast code
for a FP cavity) is going on.
mechanics: (HY,GC)
G. Cella is going to visit CIT/LIGO between Oct.19
to 29. He is
going to visit Hanford at the NSF review to understand
better
about the SUS/SEI. David Shoemaker, G. Cella and
Hiro will have
a meeting on Oct.26 at ~3:00PM at LHO about the
mechanics modeling.
The modification of the e2e code is slowly going
on to interface
well with the Cella's code. Cella uses NAG library,
which Caltech
has site license. Hiro is trying to borrow the CD
from CACR.
TAMA support:
Based on MOU#2. Hiro is going to set up the FFT program
for TAMA,
and started discussing the machine and compiler
with Dr. Ohashi.

Continued with the preparations for the NSF site review up at Hanford, Washington. This included ordering the lunches, calculating charges, gathering the background documents for the panelists, and preparing the binders for fedexing. Many thanks to Dave Beckett and Cleveland Mak for helping with the notebook stuffing and mailing, and to Donna Tomlinson for her insights into feeding a multitude of physicists.
After talking with Ed Jasnow, I called mailing services about getting campus mail codes for the two sites. Stay tuned on this one, folks. I haven’t received a definitive answer yet.
Had IFIS installed on the machine Florence Kaufman is using. I have also been searching the ACS website to obtain all the necessary paperwork and codes we need to get Florence set up properly.
Met with Joann of the PMA office at length about furniture requests for LIGO. The Division is faced with a rather tight budget this year. As a result, facilities requests are being scrutinized very closely; please be patient.
Dealt with the usual personnel issues.
And yes, the rumors are true, Janeen Romie will be moving into room 364WB in the coming weeks.
