The Project Control Meeting
Agenda for Monday January 11, 1999 will be:
(Meeting time: 10:30 am Pacific Time)
Weekly
Report Highlights
The pre-stabilized (PSL)
for the 2-kilometer-long interferometer (2k IFO)
has been running continuously
since 12/18/98!!!!!!!!
The bake out of Y1at LHO is completed.
The New Year comes in with a very busy schedule for January. We have
an end
to the bake of beam-tube module Y-1 (and start-up of staging for the
X-1
bakeout). On detector we have installation of HAM10 seismic isolation,
staging
for installation of the first BSC seismic isolation, suspension of
large
optics, and installation of the mode cleaner underway this month.
Betsy Weaver has joined the staff of LIGO Hanford
Observatory. Betsy has a BS
in Physics from Washington State University, where she was president
of the
Astronomy Club. She had worked on a number of astronomy-related projects
prior
to working at LHO last summer as a SURF student. (Betsy helped build
the
vacuum-prep bake oven system and worked up the early analysis methodology.)
Betsy will be working her way into position as technical liaison for
the
Core Optics Support installation, relieving pressure on Doug Cook,
who will
now have more time for his laser-related duties.
We are bringing on a contract technician, Bartie
Rivera, to work with Kyle
Ryan on vacuum prepping and baking. Kyle has the baking routine down
to a
well-defined, going concern and will retain overall responsibility
for bake
scheduling, technical considerations and quality. Bartie's presence
will
allow Kyle to return to other vacuum operations duties. A high priority
will
be to establish a maintenance program for LIGO vacuum equipment.
Facilities:
-----------
O. Matherny
George Grant Construction Co. placed concrete for the large retaining
wall and
half of the interior footings for the Staging building. The steel building
shop drawings were submitted to Dillman-Lvaas for approval. There is
a six
week delay from the time the drawings are approved to the time the
steel
arrives.
The retaining wall being erected:
Water System modification
Apollo is 50% complete with water modification project. The 8000 gallon
tank
was delivered but not yet plumbed in.
Compressors
We requested Sullair to give us a quote for replacing the 10 compressors
with
models that are compatible with our environment.
Air Intake Louvers
Requested a quote from Kruger Sheet Metal to install eight hoods over
the
intake louvers. As designed, the louvers froze completely shut this
week.
Seismic Isolation Installation:
-------------------------------
(C. Gray, H. Radkins)
Larry Jones, Rich Reisen, Mark Barton, and Robert Schofield arrived
to offer
assistance for SEI Installation.
Work on HAM 10 began this week. Support Tubes and Support Table have
been
installed; the Support Table was leveled (utilizing Starrett bubble
level)
and the doors were reinstalled this morning (1/6). The Bellows will
be
installed this afternoon and HAM 10 will be ready for pumping down
over the
weekend.
The last couple weeks have been spent working on the final phases of
the BSC
SEI Installation Procedure; that document is 90% complete. Accompanying
that
document is a spreadsheet to track the items needed at each step along
the
way. All other time has been occupied with the many tasks of getting
all those
parts identified, on order, designed, and in production.
All the LHO BSC SEI Piers have been grouted in place. The next task
of the
installation is the alignment of the Adapter Plates on which the Actuation
Stack is installed. That task is awaiting Tooling Bars from Allied
Engineering
which are currently undergoing stress relief. Allied hopes to deliver
them
1-15.
Optics & Lasers:
----------------
(R. Savage for D. Cook)
The pre-stabilized (PSL) for
the 2-kilometer-long interferometer (2k IFO)
has been running continuously since 12/18/98.
About 30 PSL monitor signals
are being written to an EPICS archive file
once per second. Except for a
few days (12/20 to 12/23) after one of the CDS
computers was rebooted,
there is a continuous log of the monitored channels.
The PSL has maintained frequency lock since 12/17/98.
The pre-mode cleaner
(PMC) momentarily loses lock to hop to the next
longitudinal mode about
once every two days. This is due to the known
problem with insufficient
range in the PZT length actuator. The PMC is
scheduled to be replaced in
February with one with a wider range PZT.
The monitor of the LIGO 10-W Laser output power
(before stabilization)
shows a variation of approximately -.7W, +.5W
over about 20 days.
Some of the data channels are too noisy to be
useful. This appears to be
due to a grounding problem with the model 3113
ADCs. R. Abbott is working
on a solution and we will implement it as soon
as possible.
Computing Systems:
------------------
(C. Patton)
The main emphasis over the last three weeks has been trying to fully
understand how nis+ works, trying to get the latest Secure Shell working
on the server and from there getting the client software working.
I have also been trying to get the AutoCAD key fixed and order another
license. The reseller was closed for the holidays, but I have
made
contact this week. I'm still troubleshooting the problem with
the PC
Photoreader for the digital camera.
Electronics/Electrical Systems:
-------------------------------
(R. McCarthy)
Worked Gate Valve position indication. This was rewired by PSI
and never
re tested. The valves in the LVEA now give proper indication
and we are
working some issues at the MID and END stations.
Phone lines to the mid and end station have been installed and a single
phone is operational at each building. The rest of the system
will go in
soon.
The control room laser shutdown button is being installed. The
cable is in
place need to shut down the laser and install new power supply.
(GHS note: Now that the PSL works, I guess we
need to be able to kill it with a crash button.)
PEM external temperature sensors are partially installed. This
activity
has been delayed due to tumbleweed piles preventing access to the back
side
of the BTE.
Beam-Tube Bake Out:
-------------------
(M. Lubinski, M. Guenther, and W. Althouse)
The bake out of Y1 is completed. Rai Weiss took
post bake measurements on
the tube and the results are in the "bake data"
directory under hy1. We
did have some problems in getting these measurements
because of air leaks
that developed on the RGA, but we were able to
fix them. We have started
to move equipment from Y1 to X1 in preparation
for that bake. We have to
redo some of the insulation on X1 because of
the rodent problems and Ed
Watt and his company are in the process of this.
Sun River has started to
move the DC cabling and that is going very well.
Rich Bagley from PSI is here to witness cycle testing of the south arm mid-point gate valve.
Optics & Vacuum Labs: (Jonathan Kern): Excel, the electrical
contractor, has placed duplex outlets and cable reels in the lab cable
trays, to power the flow benches and instruments that are to be located
in the middle of the labs, and on the optical tables.

The two flow benches received from Air-Tech, were found to be damaged
in shipment when we uncrated them last week. We are waiting for an inspection
by the carrier, and it looks like they will need to be returned to
Air-Tech for repair.

The holidays intervened, and the water heaters, and lab sink faucets
have been delayed, but the work should be completed 1/8. (Jonathan Kern).
Preparation for detector installation (Rich Riesen): Observed and participated in the removal of HAM#10 doors, installing the support tubes, support table and the reinstalling of the ham doors. John Worden walked me through the modification of the clean rooms so the forklift can get to the chambers easier. Went through some of procedures he has written and explained why they are as they are. we also reviewed ion pump operation. Doug Cook and I arranged for him to purchase the clean room fabric covers we'll both need (covers for the chambers and their doors). I gave him the necessary account code and he's proceeding this week. Larry Jones walked me through a good sized list of fixtures he is having built for working on and around the bsc/ham chambers. Most of these are first-time-around items and we agreed I should wait to see if they fit and work before I buy for LLO.
I talked with Terry, LHO cleaning person about what needed to be done
in cleaning the LVEA and outer buildings. There is more here than meets
the
eye. She has a local cleaning service of about 6 people, she's the
only resident (like Carolyn) but brings in around 2 to 3 people twice a
month to
keep up the LVEA and the outer buildings. I have some pictures for
a better understanding of my concerns. Huge Radkins and I discussed what's
needed at LLO for the optical alignment of the seismic iso. (a real nice
guy). Otto and I spent most of Tues. morning finding and identifying all
of the new equipment and fixtures that are required for installation support.
Environmental measurements (Mark Coles): We have been making magnetic, acoustic, and vibration measurements in the LVEA and the south End Station VEA. These data indicate that the data is within the performance specifications hoped for, although there are a number of interesting features which vary from day to day.These measurements were taken with the assistance of Millicent Schmidt and Tomyka Crier, who are both high school students at the Louisiana School for Math and Science in Natchitoches. Warren Johnson of LSU has also A report summarizing these measurements will be issued shortly. We are continuing to make further measurements which show that there are many episodic effects at small amplitude that contribute to the noise spectrum, especially magnetically, rather than observing a relatively stationary noise spectrum.
Facility issues: Control room furniture is now being installed. Office cubicles were set up over the Christmas holidays.
Computer and Network Support: Tom Evans been updating some software, setting up the Sun as a printer server, and chasing network problems. We have experienced some intermittency with the T1 connection through LSU during the holidays, which has made communication here more difficult since LSU operates with a skeleton staff during the holiday shutdown.
Site Administration: Bonnie Wascomb went to MIT and participated in educational outreach while at MIT with Rai Weiss and Jennifer Holder. She worked with the first and third grades at Fitzgerald Elementary School. They presented an activity on light polarization and propagation. Bonnie brought back the information on materials and program so that we can have that available here for visiting studets as well as classroom visits.
Other issues: The Satsuma Hunt Club will visit the LIGO site this Saturday for a tour. Chancellor Jenkins of LSU sent a personal letter to each member of the hunting club expressing his concern for the safety of LIGO equipment and personnel and asking each of the hunt club members to act responsibly. We are trying to strengthen community relations in the belief that in the long term this will be the most effective way to protect LIGO.

DETECTOR GROUP -- Whitcomb/Shoemaker
(WBS 1.2, 1.3)
----------------------------------------------------
40 m Interferometer (Nergis Mavalvala)
---------------------------------------
On December 20, 1998, a 3.7 earthquake ~60 miles south of
Pasadena rocked the 40m ifo. This being larger and closer
than our typical bi-nightly rumbles moved the optics about
enough that some radical realignment was needed. In particular,
the beamsplitter pointing to the perpendicular (South) arm had
to be tweaked to compensate for the South vertex (SV) mirror
orientation range. This seemingly insignificant
event has
uncovered some interesting phenomena for us.
Most significantly, we were able to lock the recycled
FP
interferometer in a well aligned state.
BUT, the power build-up was quite low (~3x
lower than best
power build-up in arm cavities for our usual "approaching
good alignment" state). The lock state was, however, robust
and free of the usual large 1 Hz fluctuations, which grew
only when we misaligned the ifo. Expected behavior.
Upon closer look, we found that the new beamsplitter setting
had moved the beam on the South end (SE) mirror by ~1mm and
at this new location there was a remarkably evil, bright
scatterer on the mirror, as viewed on a camera with small
aperture. We mapped out the South arm visibility as a
function of beam position and indeed found a very bad spot
at the BS setting we had stumbled onto following the 12-20-98
earthquake (visibility ranged from 14% in good areas to 34% at
bad spot). For the last several weeks we had been stewing about
how to introduce some deliberate loss into the ifo to test our
hypothesis that the carrier coupling to the ifo as we aligned
it was making one of the length error signals (RM) go to zero.
On the bright side, well, here we have it!
The upshot: instead of creating an effective loss by misaligning
an arm cavity (our usual locking state) we have an effective
loss due to some monstrous dirt and the ifo locks without
deliberate misalignment. We are in the process of quantifying
this effect, by, e.g., making a full ifo power budget in both
states. We are also in the process of scanning the beam in both
arm cavities for "good" spots on the mirrors.
Meanwhile, developement of two other techniques to probe the ifo
lock state continued in parallel.
(1) IFO AM tranfer function: Peter F. suggested the use of AM
sidebands outside the linewidth of the resonant ifo to measure
the carrier coupling. After ambiguous results, we extended this
idea to scanning the AM frequency from 0 (i.e resonant in ifo)
to ~10 kHz (non-resonant) and use the response of the ifo to the
AM sideband in the two regions to measure carrier coupling. More
ambiguous results forced us to do a more careful calculation by
including the effects of the RF modulation sidebands and mode
mismatch. We found that our mode mismatch (<~10%) imposes an
offset on the signal which is larger than the ifo coupling term.
(2) RF probe sideband: The use of a second RF sideband which is not
resonant in the cavity was used to measure the carrier detuning from
perfect resonance (reported 12/17/98). This technique was extended
to full ifo with mostly understandable results and may be used to
quantify residual length offsets in the ifo.
Finally, the end of 1998 saw the departure of
40m-ers Keith Riles
and Jamie Rollins back to U. Michigan and Koji
Arai back to TAMA,
Japan. Their presence was invaluable and they
will be sorely missed.

--------------------------------------------
SN103 10W laser has been sent back to Lightwave for repair. After the
service call which raised the output power to 11W, the power fell back
down to 10W in a 5 day period.
The 1st 10W option laser has been shipped and will arrive at Caltech
at the end of the week.

IOO Installation -
All the 3" mirrors for the 2k interferometer have been baked and are
currently being re-cleaned. During the cleaning, one of the side
magnet/standoffs broke off from the mirror. It will have to be
reglued
and rebaked.
All of the SOSs have been retrofitted and are ready for final optics
hanging, coil actuator installation, and testing.
Sany analyzed the 7W beam spot size measured on the PSL/IOO table at
Hanford by a beam scanner. The spot size measured around the designed
waist location without placing EOM on the table shows good agreement
with
the theoretical curve designed waist size and position at the center
of
the central (second of three) EOMs, and results in beam clipping less
than
10 ppm at the first EOM's aperture. The spot size measured at
the
downstream side of the EOMs with the three EOMs placed as designed
and
aligned also shows reasonable agreement with the theoretical value
that
was calculated taking into account the refractive index of the LiNbO3
and
the thermal lensing effect.
IO Machining -
Aaron's work this week has been focused on revising the 2k, 4k HAM
plan and elevation drawings.
The beamtube connecting the PSL enclosure to the HAM7 vacuum viewport
has
been shipped to Hanford.
Mode Matching Measurement -
The mode matching sensing Guoy phase telescopes for 2k are recalculated
following the changes in the optical layout and the physical parameters
of
the core optics. This time the beam parameter at the bull's eye detector
is designed to have maximum CMRR and collimated. The 4k Guoy phase
telescope and the layout on the IST tables will be done in a week,
hopefully.
Core Optics Procurement and Metrology -- GariLynn Billingsley
-------------------------------------------------------------
RM02 has been shipped to Hanford. We have approximately 1,700
independent measurements of the piece, in 4 orientations (wedge up,
wedge down, 90 and 45 degrees) off axis and in transmission.
The
transmission measurement is dominated by a thermal gradient caused
by
contact with the delran rollers which support the optic in a V block
configuration. This effect will make transmission measurements
of the
Beam Splitters and Input Test Masses difficult. However, if we
can
quantify the effect, then we may be able to subtract it.
The variations seen in measurements of Radius of curvature are being
explored. Preliminary results indicate that changes in imaging
size
inside the interferometer due to temperature change, account for less
than a tenth of a percent change in the measured radius of curvature.
There is an error in the default pixel size as calibrated at WYKO.
In
post processing the data we find roughly 200 meters longer radius of
curvature with the larger pixel size. The tolerances of this
measure of
pixel size are only roughly known at the moment, and should be firmed
up
within a week.
Core Optics Coatings -- Helena Armandula
--------------------------------------------------
>From Hanford: MMT303-1 (Florida University) and RM02 have been cleaned.
Magnets and wire stand-offs are glued.
During the cleaning process of a steering mirror (Florida's University)
a
magnet came loose. Apparently the glue joint failed; the
aluminum
dumbell broke-off very clean, all the epoxy was left on the glass.
When the
mirror was rinsed a second time, the wire standoff that was next to
the
magnet that broke-off, also came loose, however in this case, the glass
looked very clean; all the epoxy was left on the aluminum.
After talking to D. Reitze, I am going to attempt to clean the rest
of the
optics by submerging the HR side of the mirror only.
After the bake, the mirror surfaces looked very clean but did not wet.
Wetting of the surface was achieved after leaving the mirror in the
warm
(60 degrees C) Liquinox solution for over 1 hr.
Core Optics Support -- Michael Smith
------------------------------------
BEAM-DUMPS
The double beam dump prototype is still pending assembly.
ETM and PO TELESCOPE
The drawing packages from CC Development have been reviewed by Ken
M. and
corrections are being made. We expect to place an order for a production
prototype of the PO telescope next week.
PO MIRROR
Mike S. is testing the PO mirror. Slight modifications to the flexure
design are being made by Ken M.
VACUUM WINDOW
Experimental conflats and windows are being fabricated by Varian.

Design is pending.
TRIPLE FLEXURE BRACKET for BEAM DUMP
Design is on hold.
ELLIPTICAL BAFFLE/BEAM DUMP
Craig has almost completed the design of the elliptical baffle, which
also
functions as a beam dump for ghost beams which do not clear the LOS
structure.
MODE CLEANER BAFFLE
Cleaned and baked parts were shipped to LHO for installation by Haisheng
and the IO group on 1/5/99.
IO BAFFLE, 2K
The glass panels and the aluminum frame have been fabricated. The glass
panels were reworked by Ken M. and Mike S. The stainless steel mounting
brackets will be completed by 1/8/99, Paul K. is providing liaison.
Some of
the glass panels have been shipped to LHO directly from the glass cutter
in
Oregon. Conejo Industries will ship the cleaned and passivated mounting
brackets to LHO on 1/11/99. We expect to ship the glass panels and
the
cleaned aluminum frame to LHO on 1/11/99. Mike S. will be in
LHO from
1/19/99 - 1/22/99 for assembly and installation of the IO baffle.

1. Air Bearings:
Specialty Components has completed the reworking of the prototype unit
and
is shipping it today to Hytec where it will be swapped with one of
the
air bearings that Hytec is using. Hytec will then ship the swapped-out
bearing to Hanford. This triage is necessary to support the installation
in Hanford because SC's next shipment is 3/15. The protective bellows
are
still undergoing some adjustments to the curing time and temperature.
The fourth attempt is due to arrive at Specialty Components this week.
2. Actuator Components:
Hytec has placed PO with MSI to purchase the first nine sets of actuator
components for the BSC. The delivery is expected on 2/15.
3. Near-Term SEI Hardware Delivery Schedule:
1 set of BSC in-vacuo hardware (Handord)

1/15/98
4 BSC scissor tables + 2 coarse actuators
1/13/98
Suspension -- (Janeen Hazel/Mark Barton/Mike Fine)
-------------------------------------------------------------------
1. Report form Janeen:
-MMT3,2k and RM,2k have had their respective
magnets and standoffs glued to them. We begin
suspending and balancing tomorrow morning,
assuming successful bonding.
-The last recycling mirror suspension
structure, D970551, was drilled wrong.
Brookfield must reweld and remachine. They
promise to ship it Jan 18.
-Larry Wallace has been notified that our IDEAS
license is not complete. I cannot access IDEAS
drafting here in Hanford.
-Schober's delivered the last clamps for the
suspensions. This shipment closes out our
contract with Schober's Machine and
Engineering.

Detector Systems Engineering -- D. Shoemaker/D Coyne
(WBS 1.2.1.1.9)
---------------------------------------------------------
Physics Environment Monitor (David Shoemaker)
-------------------------------------------
Parts for a modified mounting place and means for the RGAs have been
specified and ordered. Preparations are underway for a week of PEM
installation in late February at Hanford.
Optical Contamination (Daqun Li)
--------------------------------
Cavity one with viton was exposed to moisture for short (5 hrs) and
long (18 hrs) periods. In both cases, there was no data change
observed
in either ringdown or mode spacing measurements. Moisture exposure
over a
longer period (a few days) for viton is underway before completing
this
set of viton. Same testing procedure including vacuum cycling and
moisture exposing will be resumed for a second set of viton which was
already requested.
Prequalification of the second cavity (empty) has been completed and
the
air baked steel was reloaded into this cavity beginning vacuum pumping.
Qualification process of the air baked steel with this cavity will
restart
for the second time since the first qualification process was stopped
because
of a large increase in losses observed for this cavity, which made
the
viton as a suspect.
Qualification of a Faraday with cavity three is near to its completion.
Manuscript writing of contamination results goes well. Each of the three
co-authors (D. Li, J. Camp and D. Coyne) has made or will make his
own
contributions. Hopefully, the first version draft will come out for
the
internal Editorial Board Sponsor in two weeks.

Near Term Installation
======================
- ASC/LSC for Input Optics week of Jan. 18
- Fiber Installation Livingston- in progress
PSL
************************
1. Boards are stuffed for the LA installation including, Frequency
Servo,
Intensity Servo, and Pre Modecleaner servo.
2. Working on the redesign of the frequency reference card for
the
upcoming installation .
3. Organized all the parts for the PSL
4. Ordered parts for the Tidal Servo including a custom insulation
"shell"
for the reference cavity.
Suspension
===============================
- Completed fab of 8 DAQ interface cards for WA 2K IO Suspension systems.
Cards
will be installed during week of 1/18.
- Fabricated 2 kapton cables for WA 2K RCM and delivered to Yehuda
for
cleaning.
IO
===============================
- System drawings for WA 2K IO controls are 75% complete.
- All connectors, cables, and racks for under IOT7, etc. are in-house
or
scheduled for delivery before 1/18.
- All IO alignment control modules are tested and ready for installation.
ISC Software development
===============================
- Initial testing of the LSC code shows that the execution time is
too long
by a
factor of ~2. We are currently working to trim the execution time by
streamling
the code, eliminating filter sections, etc.
Timing System:
==============
We received two more GPS receivers from Brandywine for a total of four.
We
are still trying to get our timing board to work with the ICS 110-B
ADCs.
We had some success in that one modified timing board at Hanford seems
to
work. We are trying to get the one at Cal tech to behave the same.
According to ICS none of their other customers have tried to use their
ADCs
with external timing (i.e. GPS) as we are. ICS doesn't seem to know
how
(most of their suggestions have not helped). But we think we are very
close
to getting it all working.
MC LSC:
===============
Discovered a minor problem with the Servo Amp design just before the
holidays. This caused us to miss the opportunity to begin board layout
during the last week of the year. We have completed the fixes and will
start board layout within a day or so. We have decided to install the
Mode
Cleaner Length Servo in 2X7 in order to keep the VCO input to the PSL
as
short as possible. We will be installing this crate and cabling the
week of
the 18th.

Completed and archived the November 1998 schedule. Started work on the annual NSF report with November data.
Worked on the schedule value of milestones for the facilities and vacuum equipment contracts for the December 1998 CSSR.
Working with Sys Admin to try to get the PMCS NT Server up. (It crashed 12/21/98)
>From: Florence Kaufman <fkaufman@ligo.caltech.edu>
Worked on format for reporting of LIGO Operations phase costs, comparing
budgeted costs to actual expenses.
Worked on schedules of the 3282 & 3283 accounts. Assisted in reconciling
of accounts.
Disputes between PSI and its valve subcontractor, GNB, have cast a cloud of uncertainty concerning replacement of the viton O-rings in the mid-point valves at Livingston. One of the possible alternatives is contracting directly with GNB to effect this change. Investigations are ongoing.
Preparations are underway to begin procurement of items required for the beam tube bakeout in Livingston. The current schedule calls for the RFP for beam tube insulation to be issued the week of January 25.
Helped organize and conduct a TRB for in-situ testing of the Livingston gate valves. The release of the minutes for this TRB was delayed pending additional information. The minutes will be distributed first part of next week. One action that came out of this TRB was for LIGO QA to look into alternate suppliers of replacement Fluorel o-rings from 3M. One o-ring supplier was called who indicated a willingness to supply a bid to LIGO. Additional contacts will made. An e-mail status report regard the one o-ring vendor was distributed.
Worked with R. Torres and L. Turner in getting approved Hanford operating
procedures ready to go "on-line". These procedures will by accessible via
the home page and the Bulletin Board.

Modeling
I missed to send modeling part of the weekly report to Albert, and he
told me to send my report to you directly.
1.4.3.3 Modeling
* IOO
S.Klimenko visited CIT to discuss about the implementation of the IOO
subsystem in the e2e environment. All the e2e related softwares on
a UFL
computer will be updated. Tentative schedule of the UFL modeling effort
in
the coming few months is as follows.
(1) building summation cavity of MC
(2) in-vacuum optics
(3) out-vacuum IOO parts using primitive modules
(4) write IOO specific primitive modules
* Adlib - single mode
Single mode code validation is over. Primitives optics and summation
cavities are all tested by comparing with twiddle and 40 data. Also
the cross checkings are done between primitives and summation cavities.
Propagator with no delay has been introduced to simulate very short
cavities and field paths outside of resonators. This has been used
to
simulate the dual recycling case. Now, dual recycling configuration
can be simulated very fast.
* Adlib - multi mode
Various validations of primitives are going very well. Now that the
power
recycling michelson cavity has been validated for a single mode case,
it
is straight forward to write a summation cavity with modes.
* Mechanics
S. Mohanty has develivered an updated technical notes he has been working
on, and he sent us a matlab code to simulate a single suspended mirror.
This will be converted as a e2e modules.
* Thermal lensing
Ray Beausoleil has delivered us a matlab code calculating the thermal
lensing effect. This will be included in the e2e code.
* Alfi
New version Alfi 3 is now very stable, although still there are some
gritches. Ed is working on Alfi4 which is based on xwWindows2.0, at
the
same time he is maintaining and improving alfi3 - all these features
will
be brought over to alfi4.
Data Analysis
o met with LDAS software programmers on Monday to discuss
efforts during the
holidays and to outline tasks for the coming week. Later
met
with the group, along with Albert to discuss progress in
these
areas (managerAPI, FrameAPI, Fcl, DB2, genericAPI)
o met with Walid on two occasions to make suggestions and
recommendations
for the Acl algorithm effort. Much of this was in
preparation for
a presentation to the LSC and LIGO coming up this week.
o met with Bruce Sears and Albert to discuss areas within
the current
LDAS software effort which could benefit from Bruce's
experiences as
he moves off the electronic logbook project.
o met with Phil on two separate occasions to discuss details
of the
assistant manager layer of the ManagerAPI. it now looks
like the
use of TCl procs instead of TCl interpreters is a better
way to
implement the assistant manager layer.
o downloaded BLAS, signal analysis and recognition libraries
from
intel for the Pentium II for benchmark comparisons to
standard C
algorithms. haven't had a chance to test any of these yet
though.
o updated mathematica licenses on 3 systems. the CIT
licenses expire
today (Jan 7). unfortunately, the LINUX license
registrations has
not work and Wolfram has not responded with a solution
yet.
o Phil continued to work on the managerAPI.tcl code.
o Dave continued to work on the FrameAPI. Dave has been
focusing on
augmenting the Fcl library. This includes the addition of
exception
handling as well as other changes to increase the
maintainability
and robustness of the code.
o Xiao worked on refining tables, writing database API
routines in C,
checking the compatibility between DB2 and Oracle, writing
test codes
to populate tables with test data, and trying to alter
tables to
evaluate the database performance.
Sears reports:
The new electronic log for LIGO is ready for installation at
the Hanford site.
(I tried this weekend, but needed someone with root
permission to create a directory
for it...)
Here is a synopsis of its capabilities:
1. Shows a calendar for quick read/write access to any
day's log (by those who
have permission.)
2. Shows all entries of to a day's log with timestamps,
color coded priorities,
and assigned keywords, as
well as the usual text
entry and an option
to upload graphics files
to appear in the log entry.
3. Allows for searches to be made on keywords, text strings
in the entries,
entry authors, entry priority,
and by log date.
4. Each group may have its own log independent of other
groups. Each group
has its own configuration
file which defines
keywords, possible
entry priorities, users
who have read and/or write
capability in the log,
user authentication.
5. Log files are in XML which will guarantee relatively
easy access by other
tools if need be.
6. The logs and log engine are kept at a central,
internet-linked location so that
remote users have easy access
to information they
have permission to see
and/or add to.
Anderson reports:
Worked on expanding the LDAS Beowulf cluster to 4GB of
memory and
diagnose/replace faulty hardware.
General Computing
MIT:
Nothing to report
Livingston:
Working to resolve some of the networking issues.
Connections between computers have
been dropping. Tom Evans is looking into the problem.
Hanford:
Received some of the networking equipment for LDAS.
The last several weeks have been spent getting the latest
Secure Shell
working on the server. Getting information and putting
together a PO to
buy the modem pool hardware. Helping to fix multiple
problems with PCs
and dealing with many "pilot" errors.
Also have spent time trying to get a new AutoCAD key and
additional
software, and trying to get the PC Photoreader working
again.
Reading up on new BRU 2000 backup software for the server.
Trying to
figure out how to write scripts to control the tape robot to
automate
server backups.
CIT:
Multiple computer moves. Mostly, PC equipment.
Samantha is updating the documentation for the computer
locations and addresses. She
also continuing her preliminary testing for Y2K issues on
the PC's.
Multiple license issues being addressed. We have received
the updates for the new year
for SDRC, Mathematica and Cadence. Presently, mathematica
appears to be the only package
that doesn't have some sort of licensing problem. The other
two packages are being
worked on.
Suresh has installed a new printer on the 3rd floor of West
Bridge and has to make some
minor modifications before it is completely on-line but
everything checks out OK on the
unit and its setup. The printer should be on-line for
general usage by the end of the
week.
Monthly backups have been performed for sirius, gsparc,
ligo, kater and e-mail.
There were a few problems caused by the power surge on
campus. Fortunately, only one
computer had to have the OS restored from scratch.
Sean (new computer support person) has
been working on
updating the modem pool and has
discovered that there are some limitations on the Livingston
box we are using. True 56K
baud rate will not be reached because of those limitations
but with some minor upgrades
there will be an improvement over the present rate as long
as the lines are clean.
Barbara has been updating the WEB pages on the various
servers.
No report received.
