The Project Control Meeting
Agenda for Monday December 21, 1998 will be:
(Meeting time: 10:30 am Pacific Time)
Weekly
Report Highlights
LHO Staging Building footers okay
Bakeout events
LHO PSL 10 watt beam makes it to the IO
Caltech Changes
to Overtime, Extended Work Week, and Paid Leave Policies
George Grant Construction
Co. placed concrete for one half of the
footers for the Staging building. After some
investigation it was
determined that the footer sizes may remain the
original 5'x5'. The
biggest damage is the one week time delay.
Apollo is 30% complete with water modification project. The tank
delivery is a long lead item. All other work is complete. No progress
on
this contract this week.
Compressors: The defective parts were replaced in all 10 air
compressors, at the contractor's expense. We are accessing the
consequential damages caused by the defective oil separators.
Bake Oven:
----------
(K. Ryan)
LHO Vacuum Bake Oven A load #6 consisting of four 3" IOO optics plus
misc. SOS magnets was released this week. Load #7 consisting of three
HAM bellows is under vacuum and will begin heating today.
Fittings were installed earlier this week which will allow the vacuum
bake oven to be vented manually and independent of the pump's solenoid
vent valves. In the past, the pump arms had to be open to the chamber
(read "load") and the pumps stopped to make use of their anti
backstreaming vent valves. Also, the control of the heating blanket
used to heat the top of the belljar (dome) was changed such that it
is
now its own distinct zone. The result is a much more uniform temperature
throughout all the zones during temperature ramps.
I have been soliciting applications at local area schools and our temp
agency for someone to take over day to day operation of the vacuum
bake
oven. Interviews will be next week.
Seismic Isolation Installation:
-------------------------------
(C. Gray, H. Radkins)
Air Bearings for HAM 8 were installed. Have an additional set of Air
Bearings, but these will be used for BSC8.
Scissors Tables and Air Bearing Dummies were installed on HAM 10.
Looking ahead--installation of Support Tubes, Support Table, and Bellows
for HAM 10 will take place during the middle of the first week in Jan.
If item delivery dates hold up, we will plan on installing remainder
of
in-vacuum hardware for HAM 10 around the 3rd week in Jan. For
preparation of LLO SEI/HAM installation, we are arranging to have Rich
Riesen up here during the first week of Jan. (possibly 3rd week as
well?).
Performance test of a HAM stack in situ is tentatively being planned
for
HAM 1 at LLO; Joe Giaime is preparing an enclosure to house an
accelerometer. Corey will plan on traveling to LLO to offer added
manpower with assembly of stacks, and will offer assistance for
performance measurements as well.
A detailed walk-through of the BSC SEI subsystem installation was done
and many tasks regarding cleanliness and safety were identified and
assigned to the members of the team. The structure of the BSC and the
size/weight of parts makes movement and manipulation of the components
nontrivial.
The BSC SEI Piers have all been located at LHO and grouting has begun
in
the outbuildings. Next, alignment and installation of the actuation
stacks.
Corey, Hugh and Rick Savage have been getting the Broadband Seismometer
going for noise measurements in the buildings that Savage and Weiss
did
not characterize. We plan on learning how to 'tune' out noise in the
buildings if possible.
Optics & Lasers:
----------------
(D. Cook)
We will get rather busy next month with the IOO and IAS and SUS/COC
and
others doing installations in HAMs 7 & 8. This will be the first
time
the PSL beam enters the beam tube as well. It has kept me busy helping
with the preparations. I have been working on two transportation carts
for moving suspended optics about. The straddle transfer lift used
for
installing the LOS fixtures and optics, has been stripped down and
sent
out for sand blasting and powder coating. The paint has been flaking
badly. The tilt platforms also have been sent out for powder coating.
I
have ordered cleanroom top covers for the BSC's to cover the openings,
equipment and the top cover when separated. They are similar to the
ones used on the HAM'S. We are continuing to collect particle counts.
We
are still improving on the over-all cleanliness as well as faster
recovery times in the LVEA.
Computing Systems:
------------------
(C. Patton)
Investigated problems with the Autocad key and Photoreader. In trying
to install the Photoreader on another PC to test the device, Windows95
encountered a protection error. I finally had to take the PC to the
local repair shop to get Windows95 fixed. The Autocad key is dead,
I'll
have to order another one. The fate of the Photoreader is still
uncertain.
Because of changing the name of the server, the nis+ credentials
database file, on the server, had to be completely updated for all
users. This file stores each user's credentials for server access.
User's are able to login and do most everything as normal without this
file being updated, however, when the user tries to change their
password they receive an error message saying they don't have LOCAL
credentials. Updating the file requires changing all the passwords
through the Solstice Sys. Admin. software. I have updated 50 out of
76
users. The other 26 are occasional visitors to the server and will
be
changed as the need arises. If anyone has problems changing their
password on rainier, let me know.
I have started installing the latest Secure Shell software on the server
and all the client PCs and Sun Workstations. This will allow encryption
of passwords during remote processes. I have also started installing
the latest version of Eudora Pro Email.
Beam-Tube Bake Out:
-------------------
(M. Lubinski, M. Guenther, and W. Althouse)
(reported by Fred Raab)
Bakeout of Y1 was interrupted
to regenerate all cryopumps. This became
more interesting than originally planned when
(1) a large amount of
outgassing from one of the cryos overwhelmed
one of the auxiliary turbo-
pump carts, (2) a repair technician shut down
compressed air to the
corner station while replacing previously contaminated
filters - thus
shutting down one of two main turbopumps at port
Y1-1, (3) the shut-down
turbopump was not able to restart due to excessive
vibration of the
turbine, and (4) a large burst of air and water
vapor was emitted into
the beam tube. A good time was had by all! Item
#1 was mostly an
annoyance; we were able to regain control by
restarting the cyro
compressors and using the cryo-head heaters to
throttle the regeneration
process. Items 2 & 3 required some significant
head-scratching and
innovation; John Worden eventually was able to
restart the turbine by
purposely introducing some vent gas to add damping
to the turbine
spin-up process. Item #4 required about a day
of intensive study to pin
down the probable cause: a leaky 1-1/2-in,
all-metal valve on the "H"
hardware at port Y1-2. (Items 1, 2 and 3 were
red herrings.)
Measures are being taken to ensure that this type
of leak will no longer
trouble us. These include installation of additional
viton valves after
the all-metal valves and changes to procedures
for torqueing up the
all-metal valves. The vibration on the cryopump
has been observed before
at the initiation of the Y2 bakeout. Having done
a thorough electrical
system check, we are suspecting that we have
a real mechanical
imbalance, perhaps due to condensed material
on the turbine. We will
extend the continuous heating zone for the turbo
closer to the region of
the region of the turbo to see if this helps.
The beam tube was reheated to 150C and has apparently
recovered from the
water burst. We have a meeting scheduled at 15:00
on Dec 18 to decide
whether to initiate shutdown and completion of
this bakeout. We are
ready to initiate shutdown over the weekend.
Personally, I was pleased by the rapid and cool-headed
response to
the unanticipated shut down of the corner-station
air supply and its
consequences. A fairly large number of people
including the regular
bakeout crew, Otto Matherny, John Worden, Kyle
Ryan, Cecil Franklin and
me worked on the physical problem in a safe and
effective fashion
and our logbooks and database captured the incident
in good enough
detail for Bill Althouse in Pasadena and us up
here to track down the
cause of the gas burst. The air-supply incident
does point out the
complex interdependence of systems at the observatory.
Although we have
daily meetings to coordinate and avoid such interferences,
this one
slipped through because we did not appreciate
the manner in which
valves were arranged in the compressed-air system.
This emphasizes the
need to understand as well as reasonable the
procedures involved when
any work is done at the observatories. We will
make modifications to
the compressed-air plumbing to achieve the full
redundacy that was
intended in the original design requirements
for this system.
Vacuum Equipment: PSI has requested LIGO punch list the two end stations. We have checked the y arm end and have generated a list of 34 items, all rather small. The x-arm beam manifold is now cooling and the 100hr test will begin today. The corner station will be complete, except punch list by the end of the year. The bake oven chamber has been received and mounted in the bake lab. The vacuum pump hardware is being set up and we will leak test next week. The bake blankets and controls will ship next Monday from HTH Heatrace. (Allen Sibley, Kerry Stiff)
Beam tube bakeout: Thermocouple installation is in progress on the west arm. Grounding of the beam tube is nearly complete. All of the cables and grounding rods have been installed, but we ran short of cable clamps. As soon as these arrive, the job will be completed. (Kerry Stiff).
Electrical Lab: We continue to receive equipment and furnishings for the electrical lab and have prepared the equipment that Rai Weiss requested in order to make vibration characterization measurements within the LVEA and end stations. This equipment has now been set up and measurements are in progress. (Juilien Svoboda)
Facilities Issues: WYE electric is continuing the work of bringing
the installation up to specifications. HPC is estimating that this work
should be complete by the
middle of January. The signing of the Mechanical Maintenance contract
(Carrier) is being held up by some legality which should be resolved soon.
We met with the Carrier
people for a kick off meeting and the service technician assigned to
our facility has been onsite for two day for familiarization.The mechanical
QA is not yet complete. We met with their QA inspector and identified areas
of concern which are still unresolved. (Gerry Stapfer)
Vibration characterization: The GRASP program has been put on
a Sun computer. Work is in progress to install LINUX and then GRASP on
a new 16G harddrive
on a Gateway PC. The GRASP program will be used with siesmic data as
an excersice in learning the frame scheme with the long term goal of addressing
LIGO data analysis and processing issues. (Anthony Rizzi).
Rai Weiss, LIGO staff, and Dick Greenwood and Kathleen Johnston from LaTech completed initial setup for seismic measurements (using accelerometers, Guralp siesmometer, tiltmeter and microphone) near the center BSC. Warren Johnson and an undergraduate student (Michelle last name?) are presently setting up their coils and seismometers as well so that measurements can be taken in parallel.
The Crime Beat: We had one additional shot fired into the west end station which was discovered last Friday morning. The sheriff's office was contacted and filed a report. The LSU Police were also contacted and they searched the woods for evidence, although they found nothing. Lynn Jelinksy, Vice-Chancellor for research at LSU was also contacted. Her office initially promised to provide night and weekend security to the site if we were interested, but later rescinded this offer when the LSU Executive Director of Public Safety said that this was out of his jurisdiction.
The Satsuma Hunt Club president has provided us with the names and addresses of all of the hunt club members and the Chancellor is sending a personal letter to each member expressing his concern for LIGO and asking each of them to act responsibly. The hunt club will also come to LIGO for a tour on Saturday, January 9.
Other: The LLO Christmas luncheon was held Thursday. Friends and faculties from Louisiana Tech, LSU, and SLU joined us in enjoying barbecue and crawfish etoufee. Thanks for your support of the LIGO Livingston Employee Recreation Club through the purchase of LIGO t-shirts!
40 m Interferometer (Nergis Mavalvala)
---------------------------------------
We continue to investigate the interferometer's reluctance to remain
locked when the arm cavity is aligned. One glaring discrepancy between
measured arm cavity visibility and optical gain of the RM servo going
to zero as we align was partially resolved. The visibility measurement
put the us squarely in the regin of ccarrier undercoupling into the
ifo,
yet we see the RM error signal tending toward zero as we mislign. A
careful measurement of the sideband coupling shows that it is not
necessary to have carrier critical coupling to zero the RM optical
gain signal. More quantitative results are being computed.
We have in the mean time developed a probe using a second PM sideband
which is resonant in the arm cavity to probe the arm cavity detuning
from carrier resonance. The probe signal worked well for a single
cavity and is now being tested using the resonant ifo.

Interferometer Sensing and Control -- M Zucker
(WBS 1.2.1.1.6, 1.2.1.1.7)
----------------------------------------------
No report received.
-------------------------------------------
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
--------------------------------------------
- Installation of the PSL intensity stabilization servo is completed.
Both
in and out-of-the loop relative intensity noise measurements indicate
that
the servo loop exhibits the desired amount of gain, which implies that
the
PSL meets its intensity noise specification.
- The LIGO standard compliant EPICS database has been tested, along
with
the necessary modifications made to the user screens. The complete
transfer to the new database is expected to be completed by the end
of
today (12/17).
- The status of the PSL construction for the other IFOs is unchanged
from
the last reporting period except for the following:
i. The physical installation
of the LHO 2k IFO PSL is complete.
Approximately 60-70% of the acceptance testing
has been completed.
ii. The output of the PSL is now available to IOO
for long periods
of time for their installation schedule (long meaning up to 10 hours
a
day). The current limitation being the occassional acceptance
test
measurement that needs to be made.
Input/Output Optics -- Dave Reitze, UF
-----------------------------------------
This report is filed from Ligo Hanford Observatory. QiZe Shu
returned from here at the end of last week. David Tanner is here
this week. Sany Yoshida is here both last week and this week.
Malek Rahkmanov and Haisheng Rong are also here working on IOO
installation.
Initially, because the 10 W beam was unavailable,
we set up a 700
mW NPRO on the IOO table in such a way that the
beam travels the
same path as the real 10 W beam. The NPRO beam
merges to the 10 W
beam path about 15" before the handoff. For this
purpose, we set
up a YAG mirror mounted on a kinematic mount
so that it can be
removed or placed back any time. In addition,
we mode matched
the NPRO beam to the 10 W beam by placing a lens
between the NPRO
and the mirror on the kinematic mount.
With the availability of the 10 W beam early this
week, the beam
was brought through the three EOMs. Only small
changes in
position were needed. The beam spot size in the
EOM region is
being measured at the present time.
Suspended optics.
Four balanced 3" optics were put in the oven for vacuum baking
and removed on the 16th. All four appear in good shape. (No
magnets fell off and the surfaces appear clean and uniform to the
eye.) The fifth and sixth have been balenced to within specs.
The last 3" mirror has been cleaned and the four magnets on the
back glued. Needed clean parts arrived from Caltech, and the two
mirrors, wire standoff, and guide rod are curing now.
One mirror (mode cleaner curved mirror MCCM2k02-1)
could not pass
the water test satisfactorily. There are two
areas, one on the AR
coating of the back surface and one on the uncoated
part of the
front surface, do not wet for long. We repeated
the whole
cleaning procedure once but we did not see any
change. We then
soaked the mirror in aceton for about five minutes
and it did not
help.
Installation procedure.
A suspended mirror was clamped (using the spring-loaded
safety
stops), transferred to a cart, carted into the
LVEA, and craned
over the beam tube to a spot near HAM7. The suspension
was then
craned back, carted back to the optics lab, and
repositioned in
the middle of the table there. The mirror was
moved by 1 mrad in
pitch by this process. We believe that this can
be reduced by some
care, and that suspended optics can be moved
sucessfully from the
optics lab to the LVEA.
Mode matching bullseye sensor.
The mode matching and Guoy phase telescope calculations are in
progress. The thermal lensing effect of the ITM will match the
wavefront curvature at the recycling mirror to the radius of
curveture of the recycling mirror according to the final design
of core optics. The mode matching telescope design has to take
this into consideration. I matched the wavefront at the recycling
mirror using two approximations: 1) a quadratic index change, 2)
thermal lensing only occurs in the ITM. The resulting change in
the mode matching telescope is small: MMT1 and MMT2 need to be
moved towards each other, MMT1 by 6.6 mm and MMT2 by 4.6 mm.
Core Optics Procurement and Metrology -- GariLynn Billingsley
-------------------------------------------------------------
We have taken a complete set of data for RM01
and will be shipping this
optic to Hanford December 28th. We have
taken a cursory look at all of
the RMs in order to survey radius of curvature.
Using the average
result for the power in C as a reference, the
RMs all measure shorter
than reported by CSIRO after polishing.
This change may be due to the
coating. Measurements at REO, CIT, NIST
and CSIRO all predict a coating
which is thicker at the outer edges, thereby
shortening the radius of
curvature. RM01 measures nominally short
of the specification (14900m
+750, -150) at 14.61Km but the uncertainty in
the measurement is on the
order of 300 meters. We believe we can
get a tighter uncertainty in the
Radius of curvature measurement and will be pursuing
this in the very
near future.
Core Optics Coatings -- Helena Armandula
--------------------------------------------------
REO Contract - COC's Coatings - The next run of coatings, BS's
and 4ITM's
is set for the end of January. REO has the new water system
and sink already in place to implement our cleaning process.
CO2 Snow Cleaning: Received a CO2 gun and a gas purifier on loan
for 30
days for evaluation.
Carbon Dioxide cleaning is a process that can remove particles and
light
organic contamination. The nozzle design is the most important factor
in
performing CO2 snow cleaning. We have three different nozzles to test.
At
this time we are working with the gun manufacturer's engineering department
to find an appropriate nozzle for our application.
At the same time, the surface of a mirror is being characterized by
Atomic
Force Microscope at JPL, before and after cleaning , in order
to observe
any surface degradation. Also, FTIR spectroscopy will be utilized
to
determine if any hydrocarbon contamination is present after cleaning.
In tests done in our lab., after exposure to the CO2 spray, water sheets
off the mirror's surface readily, indicating no traces of contaminants
(hydrocarbons).
Core Optics Support -- Michael Smith
------------------------------------
BEAM-DUMPS
The double beam dump prototype is pending assembly. Craig will take
over
responsibility for mounting the cavity beam dumps. Ken M. will take
over
responsibility for the SEI and LOS mounted beam dumps
ETM and PO TELESCOPE
Several detail drawings are still pending for the PO telescope. Ken
M. is
evaluating the drawings prior to fabricating a prototype. Jonathan
has
placed an order for the ETM telescope lenses.
PO MIRROR
Jonathan is testing the prototype PO mirror assembly.
VACUUM WINDOW
Experimental conflats and windows have been ordered from Varian to
test
indium and fluorel vacuum seals as an alternative to ISI metallized
seals.
NEW CONICAL BAFFLE at MID STATION
Design is pending.
TRIPLE FLEXURE BRACKET for BEAM DUMP
Craig is working on the design of the triple flexure bracket.
MODE CLEANER BAFFLE
The fabricated glass has been received. The remainder of the machined
parts
are in process and are expected before 12/21/98. Cleaned and preped
parts
will be shipped to LHO for installation prior to 1/5/99.
IO BAFFLE
The baffle glass support frame was redesigned to eliminate welded
construction. Paul and Angel completed the shop drawings, which have
been
sent to a vendor for fabrication. The glass has been received by the
glass
cutter and is in process. Installation is expected in LHO on 1/15/99.
INSTALLATION PLAN
A revised COS installation schedule and plan is being reviewed by Dennis
C.

Seismic Design (Mike Fine)
--------------------------------------
1. Air Bearings Protective Bellows:
The bellows is currently undergoing its third iteration to perfect
the
manufacturing process. The bake time and temperature are very
critical
to get the correct shape and size. The latest test piece came out of
the oven
with an adequate size, but failed in achieving a desirable shape. SC
is hoping
that this iterative process will be completed soon and the production
order can
begin.
2. Pneumatic Components:
Hytec is assembling a pneumatic parts list for the 1st BSC delivery
in addition
to components required for the remaining 5 BSC's in the vertex and
in the two
racks. The order will be placed late next week for all of this
hardware. At
this time Hytec will begin assembly into the rack. The pneumatic diagrams
are
currently being generated.

Physics Environment Monitor (Matt Smith for Alex Marin)
-------------------------------------------
1. The delivery schedule
has not changed this week :
http://web.mit.edu/marin/www/PEM_Delivery.html
2. The detailed PEM installation
plan will be posted soon.
3. Relocation of the RGAs
was discussed. Some minor new flanges
will be procured and cleaned for installation. The new locations
will
be on
one of the available E nozzels just avove the BSC doors(at the same
hieght as the
seismic support peirs). This will allow the ability to use a
smaller
ladder to
access the RGA and also will keep the RGA out of harms way. Further
discussion
is in process to relocate the valve for the RGA volume pumpout to an
even lower level.
4. The purchase order for the accelerometer
cables was placed with
Endevco, which will
offset the credit for returning the accelerometers(new ones purchased
from Wilcoxon).
Endevco is closed for two weeks between Dec 21 and New Years.
5. We are planning on returning the RGAs that
were part of the type B
hardware from CBI
for refurbishment. Balzers is closed the week between Christmas
and New
Years.
Optical Contamination (Daqun Li)
--------------------------------
A week of vacuum cycling for cavity one with viton still did not
bring anything up. Both ringdown and mode spacing data stay pretty
much the same as they were. We may need to repeat the moisture
exposure test for viton before terminating the test of this first
set of viton. Data taking is still going for the other two cavities
because of a relatively large data excursion observed in the ringdown
data despite a stable pattern in mode spacing data.
S.Bell and J.Camp are working to improve the performance of the
scatterometer by adding an alignment plate with a central aperture
to
the detector hex housing. This would help align the surface point under
test and the small active areas of detectors conjugate through the
focusing lens, so that the scattered light collected by the six
detectors can be maximized.
Writing a manuscript for potential journal publication of the optical
contamination results gathered so far.
-----------------------------------------
Control and Data System -- R. Bork
(WBS 1.2.2)
-------------------------------------------
Timing System:
===============
We have two working GPS receivers with the precision 2^22 Hz clock
from
JXI. We are expecting 3 more to be shipped within a week and hopefully
the
remainder by the end of the month. There is still one unresolved problem
with the Auto Site Survey algorithm that does not affect us now but
will
require a software upgrade latter when the problem is fixed. We are
still
trying to get our timing boards to work with the ICS 110-B. Testing
continues.
MC LSC:
=======
The design of the Servo Amp is virtually complete. Some minor additions
were made after discussions with Peter Fritschel. We should be starting
the
PCB layout by end of this week. We are also getting the system drawings
completed and ordering stuff for January completion of MC servo installation.
Data Acquisition
================
- Met with Peter Fritschel and Ed Daw on interface of ASC/LSC to data
acquistion system; plan is to start integration of ASC/LSC supervisor
crates to
existing DAQS system at Hanford first two weeks of January.
- Still debugging timing card interface to ADC modules.
- Initial equipment loaded into rack 2X5 at Hanford; will begin "continuous"
operation of system in late January.
- In process of adding log scale capabilities to data viewer software.
- Started work on interface to allow users to access stored data and
reformat it
to input to common software tools (ie matlab, excel, ...)

Finalized and distributed the October 1998 Monthly Progress Report. This report has been sent to the NSF.
Continued entering schedule updates for the end of November. The
majority have been updated and first drafts have been distributed.
Just received Hytec's Project '98 update and have begun reconciling the
schedule for any changes that need to
be implemented.
Worked on EAC/ETC reports for the month of November. Revising the spreadsheet system implemented last month as well as integrating the Facilities, Operations, and R&D into the format. Certain problems were encountered and have been addressed Reports are being generated for Monday's abbreviated cost/schedule review.
Created the Project Level One Milestone chart for the month of November. Verifying dates, entering past float values, and filtering the final report in a simpler, larger, easier to read format.
>From: Florence Kaufman <fkaufman@ligo.caltech.edu>
Set Up pro-forma worksheets (Excel) so that we can prepare reports comparing budget to actuals for the Operations phase starting with December 1998 results. Reports will be on a drill down basis with top level one page report providing summary data only and supporting schedules providing detail by "division" such as Hanford Observatory, Director's Office, etc. Actual figures will be taken from IFIS reports but they can be supplemented to make them more timely, by including accruals for invoices and travel reimbursement requests received but not yet processed. Updated schedules of amounts in the 328* accounts by vendor through November 1998. Vendor detail for these accounts is difficult to obtain on a look back basis once the detail is closed to the beginning balance line. Submitted entries to correct problems with Capital Industries, Heritage Landscaping, Molding Solutions, and the Petty Cash Reimbursements for Livingston Site.
Modification No. 14 has been issued to the CBI contract in the amount of $7,500 for the shipment of material from Plainfield to MIT. This was as a result of negotiations conducted at Livingston on December 3, and represents the final piece of business to be conducted with CBI. Their contract can now be closed out.
Modification No. 17 has been issued to the PSI contract in the amount of $53,441 to cover four change order requests. Funding for two of these COR's were from construction funds, while one was from operations funds and one was from the account for the MIT interferometer.
__Detector Integration Support:
SEISMIC BALANCE WEIGHTS
All parts for this order are expected to be machined
complete
by the
first
of next week. Passivation is scheduled to start on balance of
order
tomorrow
with shipments starting next week.
__Analyses: Nothing to report
__Reliability: Nothing to report
__Integrated Layout/Drawings:
INTEGRATED LAYOUT DRAWINGS (ILD) FOR LIVINGSTON
Work was started on the ILD's for the Livingston
site however,
progress is still stalled due to other priorities. Probable
restart will
be
mid January.
COVERS & GUARDS FOR HAM & BSC CHAMBERS
Drawings are being updated for purchase of final
quantities of
large
& small O-ring guards & nozzle covers both for HAM & BSC
chambers,
for Hanford & Livingston. This project started late due to other
priorities
but should be complete today for ordering of hardware for January
use.
X-BEAM & Y-BEAM SPOOL BAFFLES
Detail drawings are in process but, low priority. New
schedule
is in
the process of being generated.
__Mock-ups: Nothing to report
Modeling
Hiro:
mechanics
S.Mohanty of Penn State has completed a new working note
describing the
formulations of his modeling work of the mechanics system in the
End to
End model, including some numerical calculation results. The note
is
available in
/home/e2e/Software/docs/e2e/mechanics/Somuya-12-16-98.pdf
or through the e2e home page http://www.ligo.caltech.edu/~e2e/.
COC
The summation cavity of the recycled michelson is kept going. The
first
comparison of twiddle, e2e using primitives and the one using
summation
cavity are done. We need further development, but we will have a
fully
functional - with modes - michelson summation cavity soon. One
observation
is that it takes 0.3 seconds that the whole cavities are filled
with
steady state fields. In order to speed up the simulation, a new
function
will be added to adlib to save and load intermidiate state, so
that one
can start simulation from the point where it stopped last time.
dual recycling configuration
As a part of the validation of field/optics, the dual recycling
configuration has been tested by comparing with the twiddle
transfer
function. After fixing one mirror problem, e2e reproduced the
twiddle
result. So the dynamics of the dual recycling configuration can be
studied
- although not quite fast from the speed point of view - using
e2e.
alfi
The new version of alfi version 3 is being updated to make it more
stable.
IOO
S.Klimenko has started the development of IOO part using e2e
framework.
He will visit CIT from January 5 to coordinate the future work.
AL NOTE: Taking advantage of Peter Fritschel's
and Ed Daw's visit
to Caltech, Hiro and Biplab met with them to
update them on the
status of the E2E work. Peter indicated he will
start to excericse
the model and start looking at building simulation
components for
LSC/ASC control loops.
Data Analysis (KB/HY/AL/SA)
Kent is on vacation. No reprot received for LDAS development.
However We are still interviewing for programmers and have taked
to ~4 this week. Ehrens is working to complete the managerAPI
before Xmas. Farnham is working to build the FrameAPI within the
same time constraint.
S. Anderson:
Finally isolated the poor IBM to SUN ATM performance as being
caused by a faulty
ATM card in the SUN.
Worked on generate a more detailed mass storage purchasing plan.
X. Hu:
* Installed DB2 software on spica
* Installed DB2 on Barbara's NT machine
* Tested the SDK using different methods
(static embedded SQL, dynamic embedded SQL, CLI).
Comparing the advantages and disadvantages of each method.
* Studying how to handle BLOBs (that's something new to me).
* studying how to use net.data to access DB2(Roy's request)
What I am going to do next week(or next few weeks):
* Contact with Rolf to discuss
the content of data source
the table design
potential database access
scenarios
prototype of database access routines
AL NOTE: This week we met with Rolf to discuss
how DB2 would need
to be used to support detector/cds DBs, such
as machine state
vector, hardware inventory, etc. To this end,
we will get
BarabaraK involved in working with Xiao Hu in
support of CDS
needs.
General Computing
MIT:
With the Tom E. going to Livingston the Sys. Admin. duties have
been divided up
between Ed D., Joe G. and David S. .
Livingston:
Nothing to report
Hanford:
Changing the name of our server required the nis+ credentials file
to be completely recreated for all users. If anyone gets an error
when
trying to change their password on rainier, please let Christine
Patton
know.
Multiple PC software problems have been resolved. Installed
Secure Shell
on the server and on all client machines (PCs and Suns).
Installed the
latest version of Eudora Pro Email on all PCs.
CIT:
AL NOTE: We have hired a contractor to support
Larry and Surech in
system administration tasks. Sean Scanlon starts
next Monday.
Barbara reloaded the antares pc as an NT server. Moved the DCC
test application
to antares; it worked just fine. Next step is to move the
production files.
Barbara updated WebDocs as of December 15.
Barbara loaded DB2 Workgroup Edition on NT machine in Millikan.
Began reading
through manuals and working with sample database.
Made LIGO web site changes to LIGO Talks, Seminar Transparencies,
Publications, and Employment pages.
Barbara fixed several references to Vancouver and ICHEP on the
Amaldi site. Two
applicants have registered so far. Barbara is also keeping a
paper backup of
applicants until a zip drive is available.
Suresh had a number of the printers repaired and cleaned as well
as put through
a number of PR's related to the repairs.
Once again CADENCE is being reloaded. So far it has been going
smoothly other
than it now requires 4GB of disk space to load. It should be
finished and ready
for testing by Friday the 18th.
Added and modified some LIGO email aliases.
Worked with Stuart Anderson to isolate the problem with data
traffic to his
System called jelly. Eventually his ATM card was found not to be
functioning
properly.
Doing tempory installation and testing of Unix utilities software
brought by
Larry from LISA conference. Some of them seem to be useful to us
while building
the new server.
Performed restoration of deleted user's files from tape backup.
Samanth is looking into year2000 complinancy items and found the
software
necessary to test the PC's. Tested most of bridge for y2k, back
orfice, and ran
Norton on the PC's. Placed a little sticker in the corner of the
monitor of the
computers that have been tested. Hopefully all will leave them
alone, so that
when Sam believes she is finished she can just check that the
monitor has a
sticker.
Sam and Ed C. finished packing the computer to be shipped to
Livingston.
There are now three computers in wilson that do not pass the bios
2000
test. One of them will does go to 2000 if you test manually.
Still need
to look into the others.
Found quite a few PC's espiecially in Wilson house that are old
and have
very full hard drives. Found this while running NOrton utilities.
These are
issues that will have to be acted on in the near future.
Sam still needs to find a way to test the NT machines for
compliance. They do
not easily boot to dos. Will probably try using a boot disk to
get them
to DOS. She will also be checking on getting things to do more
extensive testing
for Y2K compliancy for the machines that have not passed.
Presently, working on procurements to upgrad the network equipment
and improve
the space utilization in the computer room.
Dorothy Lloyd
Dot discovered that three weeks’ worth of work had disappeared from her machine and is currently busy restoring the lost data.
Rita Torres
Rita is on vacation.
Irene Baldon
Please note that this report is for 4 days only. I was out ill on Wednesday, 12/16.
Worked on the ever present backlog of paper work for various trips taken recently (17 Purchase Requisitions and 5 Advance Requests). Also worked on the ever present backlog of Expense Reports (24 Expense Reports). The backlog is slowly but surely going down.
I am now arranging and preparing the paper work for MIT trips to our 2 sites and CIT. Your cooperation in assisting me with the taping of your receipts on 8-1/2 x 11 white paper and filling out your own Expense Reports will greatly help in processing your reports in a timely manner. This will enable me to do a speedier audit and only require changes when necessary. If you are not sure of the per diem, or anything else, please leave it blank, as well as the totals at the bottom, and I will fill it in.
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.
Elizabeth K. Wood
Did several personnel requisitions for potential new LIGO employees at Livingston, Hanford, and Caltech.Talked to the phone office about installing new extensions, deleting an old extension, and requested a repair to Bill Althouse’s malfunctioning phone.
Attended a class given by Sponsored Projects on the grant preparation and submission procedure.
Began to fill out a rather lengthy survey from Payroll concerning the schedules of Caltech employees (non-exempt, exempt, and hourly).I attended a very lively meeting conducted by Human Resources concerning the 1999 Policy Changes in Premium time, Paid Leave and Medical Coverage on Tuesday, December 15, 1998. Beginning on December 21, 1998, Caltech is adopting the provisions of the State of California’s laws. See details below.

Changes to Overtime, Extended Work Week, and Paid Leave Policies
Overtime is no longer calculated on a daily basis. Non-exempt employees will be paid overtime for hours worked in excess of forty hours in any workweek.
Employees will no longer be paid overtime for hours worked in excess of eight hours per day. However, the Institute will continue to pay double time for all hours worked in excess of twelve hours per day.
Holiday, jury and witness duty, bereavement, and sick leave are considered time worked when computing overtime.
The new overtime calculation method will give you and your supervisor/manager more flexibility in planning your time. It makes the choice of overtime pay or time off available to you within the same workweek, subject to agreement with your supervisor/manager. Time off must be granted in the same week in which the overtime is worked.
Paid Leave
The Institute will increase the number of accrued sick leave days you may use to care for ill family members. The current 10-day cap will be increased to 20 days. The additional 10 days will apply only in cases of a serious family illness as defined by the FMLA (Family Medical Care and Leave Act; see Personnel Memoranda 26 for eligibility and requirements). If eligible, you will now be able to use up to 20 days of accrued sick leave for FMLA family illness.
The Institute will continue to pay its portion of medical insurance premiums for the first 6 months of an employee’s medical disability.
