LIGO I Construction/LIGO Laboratory Administration (Lindquist)

LIGO Operations--Administration

A Site Teleconference was held on Thursday, Frebruary 28, 2002.  The agenda included the status of FY 2002 costs-to-date, of NSF funding and the Cooperative Agreement, the establishment and budgeting of FY 2002 accounts, the FY 2002 Financial Reporting format, as well as the status of the construction at the two sites.

• It was noted that there has been a general, but significant, slowdown of the ORACLE Financial Systems at Caltech.  ORACLE hardware and software people have been brought in to troubleshoot and resolve the problem(s).  Meanwhile, paychecks have priority, and a lot of other financial processing has been deferred.  As a result, the reports at the end of February will probably be light.
• The building status at Livingston is still tight relative to the LSC meeting scheduled later in March.  The biggest item is still the audio/visual equipment.  Cabinets are supposed to be in next week, and if they arrive, installation should support the LSC meeting.  Otherwise work around will be required.
• The rest of the construction effort at Livingston is "reasonably slow!"  Conducting a walkthough tomorrow (Friday, March 1) to establish a punch list.  Retention is being kept pending punch list and completion of auditorium in time to support LSC meeting.  There was expressed so much dissatisfaction with the finished work on the outside that will probably want significant retention.  Question what it is realistic to expect to be reparable.  Ed Jasnow's position to be sought.  Gary to talk to Sandy Pool.
• Conversations with electrician at Livingston indicate that for a long term solution it should be possible to get a lot more power to the seats (for laptop computer operation).  For the short term (LSC meeting) it may be necessary to run some power cords (recognizing limitiations imposed by need to avoid hazards).
• At Hanford, steel is up and roof is being welded.  Lost three weeks, but were sufficiently ahead of schedule that are now not far off relative to original schedule. ontractor is aware of need to support LSC meeting at Hanford scheduled in August. Barry did a walkthrough and noted that seeing the building in current state, it seems bigger, and it will be an unique structure that should create a good impression for visitors arriving at the site.  Visual impact provided by different wings and roof angles, which are simple architechturally, but work to make the building attractive.
• Property: furniture is being packed.  Ed Chargois is expecting a list today, which he will forward to interested parties.  The electron microscope will require expensive repairs and is, therefore, being dropped from consideration for Livingston.

From: "Brambila, Ruth" <Ruth.Brambila@caltech.edu>

• Completed change order #30 on NYMA and routed for signatures, completed change order #6 to Benton PUD, and working on change order #1 to American Electrical.  Working on completing EGO.
• Have been on jury duty for 4 days out of the last 5 days.  Jury duty will most probably be completed today or latest tomorrow.  .

• Spent considerable time working on funding realignments for the FY2002 award, which were requested by Federal Accounting because of the Oracle system requirements for billing the National Science Foundation.  This was necessary because the award was currently funded at only $14 million, while the existing Oracle budgets had been set-up on an at risk basis at $28 million.  Also, realignments were necessary because budgets for the various cost centers had to be adjusted for the approximately $3 million of FY2002 expenditures which were paid from FP2001 funds. Realignments were also required for the eight Equipment Fabrication accounts that have now been approved in the FY2002 budget.  A further complication was that the adjusted Oracle budget for each project had to equal and or exceed the costs and encumbrances to date for that project.  In some projects, large open encumbrances, particularly for labor contracts for the rest of the fiscal year, meant that the Oracle budget for these projects had to be set at an amount larger than 50% of the LIGO budget for that project.  The Office of Sponsored Research requested that all budgets be broken down by expenditure type which also adds to the difficulty of preparing these realignments.
• Met with Donna to go over the Visitor Program report for January 2002.
• Provided information requested related to the recent CCB.
• Continued working on reports for February 2002.

• Financial reports can be found at: http://docuserv.ligo.caltech.edu/~fireport

From: irena@ligo.caltech.edu (Irena Petrac)

• HPD: CO No. 06, adding funds to cover the scope increase and overrun incurred to date, was processed to Purchasing.

• No report this week (jury duty).

SUPPORT (Baldon, Torres, Lloyd, Tischler)

• Processed the paper work for seven (7) new/revised trips.  I have nineteen (19) trips in various stages of completion before ticketing can be done and paper work completed.
• Completed seven (7) Expense Reports and there are three (3) reports yet to be done.  I'm holding one (1) report which requires a check to close.  I closed all 2001 trips and all files have been forwarded to DCC for permanent storage.
• Reconciled P-Card items which required telephoning vendors to track down which traveler incurred which charge.
• I continued to work with Montrose Travel to work out various kinks, etc.  Ticketing has started and progress is being made.  At this time they have received 21 Traveler Profiles.
• Worked on the preparation and distribution of the Travel/Vacation Itinerary for February 25, 2002.  Performed normal recording and filing associated with Travel and Reimbursement.  Also performed miscellaneous duties as requested by various members of  the LIGO Project here at Caltech as well as from members of the staffs of each of the two (2) sites.
• I continue to do MIT's travel to the sites for installation activities and also to assist them wherever possible.

• Ruth was out on Jury Duty (Friday, Tuesday and Wednesday) and Gina was out sick (Monday and Tuesday). Hence, transfer of contracts, blankets and POs to FY02 POETAs, along with processing of POs and Change Orders on contracts were minimal this reporting period.
• Esther and I managed to process 30 invoices for payment this reporting period. This low number is was due to the problems we have been having with Oracle.  The total incoming invoices received for this period can be seen in the "Cost Schedule Control Systems" report by Esther Cunningham. I tracked and followed up on some invoice problems and reviewed and recorded payments processed by Esther the week of February 18.
• Processed the usual requisitions, change orders, etc. In Gina's absence, I also created seven POs and made additions/changes as requested by the end

user on a couple. Gina will follow up on and obtain confirmation from the suppliers for these orders on her return.
• Continue to monitor contract and blanket order encumbrance and notify task managers when supplements are needed.
• Jim began working full time on data entry and updating files in my office. He will resume his schedule of working for the DCC in the mornings and me in the afternoons on March 4.

• Scanned several documents for CEGG, submitted these to the DCC, then updated the roster with info from their Attachment Z.
• Met with L. Turner and T. Frey to discuss how personnel data relate to and can affect the roster data.
• Arranged a telecon for the Gingin advisory group, and also for the CCB which took place on 2/26/02.
• Updated site trips.  Placed several Pcard orders, and reconciled a few.
• Spent some time trying to accommodate a vendor that at present does not take credit card.  Turns out that the vendor is just days away from installing the system, so that payment will be done by credit card after all.

• Met with Jill Perry in CIT Media Relations in regard to Press Kit.
• No other report besides usual duties.

No report this week.
 

LIGO Hanford Observatory (LHO) Operations (Raab)

no report

LIGO Livingston Observatory (LLO) Operations (Coles)

CDS: Made a list of software changes/upgrades to be done at LLO. Also included
were some hardware requirements. Upgrading london to a new ultra 60 on
Friday. Moved all the web page files to the new machine. Configured it to
run on ATM. Working on fine tuning the MC Auto Locker script. Wrote test
code for xycom 200 and pentek testing. Created a new medm screen for weather
stations. Checking on disk to disk backup of LLO1. Planning on making the
disk backup of london after installing new london. Added additional licenses
for MATLAB and installed DSP blockset. (Chethan Parameswariah)
 

LDAS; Reconfigured backups at sites to use cron instead of internal DB2
scheduler (the advantage is the possibility to use scripts instead of
GUI). Restored LHO_1 and LHO_2 backups at LLO and LLO_1 and LLO_2
backups at LHO. Finished reading "Fundamentals of interferometric
gravitational wave detectors" by Peter Saulson. Read first 2 chapters from
DB2 Replication guide. Got quotes from USPS and couple motor freight
companies for shipping Beowulf PCs to MIT. Called SUN to schedule power
supply replacement for SunFire machine. (Igor)
 

Ordered ram for the beowulf.  The first batch that was ordered
was back ordered indefinitely, so the order was canceled and reordered
from a different vendor.  Pricing the fiber to run to the new building. (Shannon)
 

GC:  Ran network cables new building in prep. for the LSC.  Checking
into the fiber & cat5 terminations in the new building.  Checking on
fiber prices for ldas/GC.  Wrote a script to manage group IDs for NIS+.
Finished a web page for tracking IP address allocation.  General
preparations for the LSC meeting. (Shannon)
 
 

IFO: The transfer function of the mode cleaner servo was measured including the
crossover frequency between the MCA path and the PSL path.   The unity gain
frequency is about 15 kHz.  The crossover frequency varies between 100 Hz
(lowest) to about 350 Hz (at robust locking mode).
 

The air legs on the PSL table were removed after they apparently sprang a leak. (Joe Kovalik)
 

Optics and Installation:  The installer reports the Laser Safety Interlock
complete and ready to enable.  We will issue access cards following a
training session next Monday. Piecing together some DC photodiodes with an
imaging system to monitor scatter of the cavity optics.  Working with Dr
Weiss and Peter Saulson to design a system to detect shorter wavenlength
harmonic generation on the large optics. Staged material and assisted Joe
Giame in measuring the transfer functions of BSC piers.  This is ongoing. (Jonathan)
 

Control Room:
On screen help files are being updated and in some cases generated.
The Mode Cleaner AutoLocker has been tested and needs a little fine tuning.
A Spectrum Library is being created and should be completed in 2 to 3 weeks.
The pictorial configuration control on the ISC tables is 80% complete.
The MEDM Weather station screens have been reconfigured for better access.
Other:
The annual crane inspections have been completed only in the corner
station, the end stations will be inspected next week. There were no major
problems with the cranes inspected.  (Rich Riesen)
 

Detector/Technical Support (Whitcomb, Coyne)

40 Meter Interferometer (Weinstein)

• PSL (Abbott, Ugolini, Vass, Smith, King):
• We have been flowing N2 into the Lightwave box for the last week. It's now pretty clear that the two power monitoring diodes internal to the Lightwave MOPA (PSL-126MOPA_126MON, monitoring the power from the NPRO, and PSL-126MOPA_AMPMON, monitoring the power from the power amplifier) are strongly dependent on humidity. Steve stopped the flow of N2 into the MOPA box somewhat less than a day ago, and the 2 signals resumed their their traking of humidity.
• We have observed ~1/2-hour-period power variations in the past few days, which are real (they are also seen in the external Vector power calorimeter). They're not associated with the N2 flow. They'e not optical feedback into the NPRO, since we don't see them in 126MON. Could they be optical feedback into the power amplifier? Hard to believe, the light has to get back through a Faraday isolator (unless the back-reflected light is coming from a device between the PA and the Faraday). Maybe it's something entirely different...
• Ben and Dennis have scoured the PSL table for possible shorts to the rack ground, and have fixed all possible sources. There's 6.5KOhm between the PSL table and rack ground.
• Dennis and Steve are making the required modifications to the PSL layout (new low-power pick-off, mode-matching lenses, circularizing lenses, etc.) After a first round, the beam was steered into the PMC, which resonated with a 40% visibility. He is now tweaking the mode-matching to bring that up.
• We await Rich Abbott's help to commission the PSL reference cavity heating system.
• A Coherent LaserCam CCD beam profiler has been recieved. We expect a new BeamScan in a few weeks.
• Suspensions (Romie): Bartie at LHO is cleaning and baking the 40m test mass mech. parts. His schedule has fallen behind due to a potentially faulty RGA but we are still on schedule.
• Suspension controllers (Ben Abbott, Jay Heefner):
• Bob Taylor is about done with the wiring for the first of 3 cross connects (two for the digital suspension controller, one for the MC LSC/ASC).
• Ben has tested two pole/zero modules that now wait only for their front panels to arrive before they are installed into the 40m. This is one of the last modules needed for the MC suspensions.
• Ben has begun drawing the video wiring diagrams for the 40m lab. The drawings for the other systems that will be installed in the same rack will be started soon.
• Jay has a first draft of the timing system for the 40m CDS. He continues to work on the timing, RF distribution, and reflective memory layout for the suspension controllers and MC controls.
• Ben and Jay alert us to the fact that the CDS group will have its hands full preparing the sites for E8. We will need lots of help with cabling, and SUS/LSC/ASC software. It's not clear what impact this will have on the 40m effort, but it may be very significant!
• We hope that a stand-alone suspension controller will be shipped from LHO by Richard McCarthy next week.
• Optical layout (Smith):
• IO PERISCOPE: A PO has been sent to ASCO; completion is expected by 3/15.
• ILLUMINATOR: Preliminary designs for illuminator housings for each chamber were completed and incorporated into the 40m integrated layout drawing. The locations of the illuminators have been passed to Ben who will include them in the controls drawings.
• AP1 and AP2 ISC TABLE: The AP1 and AP2 optical elements were incorporated onto the AP1 table, and the table was moved next to the output chamber at the same general location as the prior AP2 table. This eliminates the long path to the AP1 table and consolidates the AP beams close to the output of the IFO. This also makes the layout of the CDS crates easier.
• PARTS ORDER: The IO, IMC_R and IMC_T parts have been received from all vendors except optical mounts from Newport, PZT tilt platform from Polytec PI, Uniblitz shutters from Vincent Assoc., beam dump glass from Hydratech, The machined parts from ASCO are in process.
• South Annex Bake oven chambers (Vass, Taylor, Cardenas):
• Bob has cleaned and baked the 8 cable assemblies, 30 teflon seals, 30 viton "O" rings.
• Bake Oven # D, large oven, rough pump failed. After oil change and cleaning the liquid nitrogen trap, the pump regain max. vacuum pressure. The bake oven has viton o-rings and teflon seals and it is under vacuum; should be finished by Friday.
• Small bake oven # B. containing cabling parts, baking completed and RGA scan performed for AMU components 41,43,53,55 & 57 with an outgassing rate of approximately 4E-13 torr.
• Bake oven # C is pumping down with Fluorel parts (not to bake) that has been boiled after bake.
• Bake oven # E new oven still waiting on the new oil-free scroll pump station from Varian.
• New Air bake oven received it and installed it in place.
• Facilities (Vass, Jones, Smith, AJW):
• In vacuum suspension cables: Etzel's lab completed all 35 cables. The first 8 have been cleaned and baked, and Bob will do the next 27 in the coming weeks.
• Bob will also need to bake the optical viewports and flat flanges (to replace the old o-ring sealed feedthrough flanges).
• Bartie at LHO is getting dirty RGA scans of the new feedthrough flanges, but suspicion is falling on the RGA, not the load.
• Larry continues to work on the design of ISC table enclosures and beam tubes.
• STACIS readout gets hung after a day or 2 (we have the same problem with the serial readout of the ion pump controllers). Dennis is trying to diagnose and fix this problem, but it only happens after a day or 2 of normal readout.
• We continue to await a plan and an estimate for reducing particulate content in the IFO hall, from Caltech HVAC experts. In the meantime, we will look into getting stand-alone HEPA filters.
• We will vent and begin the installation of the mode cleaner tube extension, 2 remaining seismic stacks, all in-vacuum cables, clamps, feedthroughs, optical ports, etc, next week. The installation will procede in stages, interspersed with pumpdowns and RGA scans.

LASTI (Zucker)

LASTI (MacInnis, Mason, Mittleman, Ottaway, Rollins, Shoemaker, Zucker)
=======================================================================
 

VACUUM ENVELOPE:
Using site and PSI test chamber data we
verified that our water and air signatures are consistent with degassing
of Flourel spring seats and O-rings.  Making one last attempt to
resurrect our RGA electron multiplier before we vent for stack
vibration tests (see below).
 

EXTERNAL PRE-ISOLATORS:
 

In situ BSC stack characterization (Mike and Rich and Myron):
 

We received two shaker setups from LHO to support the test. LLO
is repeating the pier test and will ship back the remaining complement
of shakers and accelerometers end of this week.  We currently plan
to be ready and backfill to install the instrumentation by
Tuesday.
 

Pre-isolator mechanical design/fab (Ken):
 

Completed the fabrication drawings for all long lead componants. Visited
several machine shops and fabricators with drawings for quotes. No one
had a problem with a 4/19 delivery.
 

CDS/DAQ/GDS:
No problems to report.
 

PSL:
This week the one meter SOS test cavity inside HAM13 was aligned such
that bright TEM00 mode fringes were observed. Work testing the FSS
servo continues; the problem that arose was amplitude and phase
instabililty in the pockel cell which resulted in an unstable cross
over between the fast path and the PC path.  This (we think) prevented
stable locking. Work is in progress to cure this problem.

Data Analysis and Computing (Lazzarini)

E2E MODELLING:
_______________

Hiro attended a workshop in Kyoto University, invited by TAMA group, to give a
status report of LIGO. The talk covered LIGO I, E7 run and advanced LIGO. During
his visit to Japan, he contacted several TAMA people to exchange opinions about
the collaboration between TAMA and LIGO.

LIGO Data Analysis System

Software Systems (Blackburn)

The modifications to the dataConditionAPI and wrapperAPI to support the
passing of FrDectector geometry data continues. Work in the wrapperAPI
is almost complete. The dataConditionAPI support the geometry information
only for the simple cases of timeseries and frequencyseries which are not
operated on. Work continues on the complex cases.

Continued to refine a few points in the new resampling library used in the
frameAPI and dataConditionAPI. More testing has been done at the TCL layer
and more unit tests have been added to the make check.

The development of a new action called shifter() which is a simplified
interpolation routine has begun. This is the only new action being added
to the dataConditionAPI in this release, though more work is also still
needed on the Kalman filter action.

Added new user command activeJobSummary which reports the status of all
jobs currently running or queued in the local LDAS installation.

Added support to mpi API for LDAS e-mail messages to be generated based on
embedded strings in wrapperAPI shared object status reporting code. This
allows dso developers to have themselves be notified via e-mail of notable
conditions arising during data analysis.

Factored out all file type tests required within LDAS into the genericAPI
procedure "fileType". This allows for all necessary file types to be
identified from a consistent interface in all file input routines.
A corresponding procedure for typing the contents of tcl variables is still
needed for file output routines.

Continued integrating diskcache API into LDAS.  Many complex/compound
-framequery options were resulting in erroneous output or error conditions.
A full set of tests are required to verify that all conditions are now
supported properly.

Added a sanity check to the LDAS generic API socket communication callback
"reattach" so that malformed return values from API's to the manager
generate descriptive messages as opposed to "unexpected socket closure"
errors.  Analysis showed that these types of errors are never fatal to the
LDAS job in which they occur, so they are treated as warnings now.

Began reimplementing diskcache API cache data structure according to new
design worked out in meeting with Kent Blackburn. The specification for this
persistent form of this structure will describe the structure.

Added rotation to logging of job success/failure data file generated by
manager and used by controlmon API for statistical calculations.  This
file grows by one megabyte per 25,000 jobs; it is now rotated when the
size exceeds one megabyte and the old file is timestamped and moved to the
log archive.

Began writing per-API statistics generation routine which will maintain
data on a per-api basis of jobs succeeding and failing, how often the API
is restarted, and each API's uptime.  Report generation and persistence
across system restarts via a state file are pending.

Lazzarini: We have discussed with the detector group the timing of making a transition to the next release
of the frame specification that has been agreed upon by Virgo, LIGO, and the LSC. It will likely not happen before
S2 due to personnel constraints (too much to do for S1).

(Dan Kozak)

* Continued HPSS migration from Redwoods to 9940s.

* Still trying to get StorageTek to make good on coming up with a
  replacement Ultra 10 (they in turn are trying to get Sun to do it, with
  a little help from me via Linda Feather).  Still no concrete results.

* Mostly worked on setting up the LIGO SAN testbed.  Accomplished so far:

    SAN admin network set up.
    Firmware upgraded on switches, HBAs and T3s.
    Relevant Solaris patches applied to SunFire machine.
    9940 drives connected to switch via fibre.
    9940 drives given basic test (tar files to and from tape).

* Now working on details of SAN configuration (specifically setting up a
  multi-switch fabric so we can test inter-switch links).

(Al Wilson)

* Prep work for the new network switches. Ran cables.

* Had to make some changes with the cfdef file so the Linux def's will work
  with version 5 of the installer (cfdef)

* Working on tripwire, ran some test with it reporting to big brother. The
  project is coming along fine.

(Stuart Anderson)

* Finished integrating the new SunFire V880 servers in the ldas-archive,
  ldas-lho, ldas-llo. Started integration in the completely new ldas-cit
  system.

* Shutdown the ldas-test and ldas-cit system for construction work.

* Created a new top-level /lal directory structure in the ldas-dev system
  for the LAL code contributed by the LSC to run in LDAS. If this works
  it will be replicated on the other LDAS systems coincident with the
  next LDAS software release.

* Verified that Gigabit Ethernet works over 450m of the new 50micron
  multi-mode fiber installed at Caltech.

  DB2 Replication guide.

* Got quotes from USPS and couple motor freight companies for shipping
  Beowulf PCs to MIT.

* Called SUN to schedule power supply replacement for SunFire machine.

(Shannon Roddy)

* Ordered ram for the beowulf.  The first batch that was ordered
  was back ordered indefinitely, so the order was canceled and reordered
  from a different vendor.

* Pricing the fiber to run to the new building.

(Greg Mendell)

* The host dataserver is now gateway on the LDAS network. A new
  dataserver, a SunFire 880, was brought on line. As a part of testing,
  the new server is running the ligolwAPI.

* The LDAS network backup script was updated to include the new server,
  and reflect the name change of the old dataserver to gateway.  The
  ldas_admin_all mailing list was informed of the needed changes to this
  script.

* Rebooted the Sun Blade 100 admin host to complete installation of
  kernel patches that were applied by Stuart.

Data Analysis Activities (Lazzarini)

Shawhan:
I have been overhauling the
http://www.ldas-sw.ligo.caltech.edu/ligotools/faq LIGOtools
Frequently Asked Questions page, adding several new notes about
working with data from the LDAS database, etc.

Tracked down an apparent discrepancy in the list of "clean locks"
during E7, finding it to be due to conlog overestimating the length
of locked segments (since it records the time when the LSC servo was
turned Off, which is typically a few seconds after the interferometer
loses lock).

T. Creighton:
This week I submitted the new LAL inspiral simulation interface
function, and have been working with the AEI at validating my pulsar
modulation and their pulsar demodulation code.

Mendell:
1) A memory problem at LLO that was causing the frameAPI to crash when
knownpulsardemod DSO ran has been fixed.  (The problem was caused by
large files stored in /tmp on the server running the frameAPI.)

2) Saving SFTs data as COMPLEX8 instead of as COMPLEX16 will reduce the
size of SFTs by 2 without loss of precision.  (SFTs are computed using
LAL functions to single precision only, regardless of how they are
stored.  However, the LALDemod function currently inputs SFTs in double
precision.)  This will require only a minor change to the
knownpulsardemod DSO.

3) Bugs in the clean_locks reported for E7 are being fixed. SFT
generation will begin again, once new clean_locks are posted.

bandwidth usage for the T1 line.

CIT:
(Mike)
-Working on Mohanna's computer troubleshooting some hardware problems
that she was having with her computer. This is looking like a secondary IDE
controller is going out on the motherboard. I made some adjustments to keep
her up and running.
-Loaded two new PC's with win2000 with all General Computing Software.
-Loaded a PC to be placed in synchrotron for Riccardo.
-Received two new PC's that I checked out to make sure they were what we
ordered and I now am going to reload one of them with win2000 for Cindy.
-Assisted Larry and Lisa on configuring gige network.
-Pc72 is hosting Project Science website which is having a slow response
time; looking into stopping some services and a few other changes that
might help increase performance.
-Backing up a Optics Lab PC and getting it ready for a reload this has win95 and
is to be upgraded to win98.

(Veronica)
- LIGO website: updated Employment, worked with Bonnie Wascom on LSC March
registration form; submitted the new LIGO roster pointer to Caltech
Reference Desk webpage; updated Student Programs, LIGO Participation.
- CaJAGWR: Posted updates to the seminars page.
- Worked with General Computing group on LIGO website's access issues: The
website was inaccessible from a subnet, which was blocked due to a recent
hacker attack.
- Worked with Mike on web-hosting for Project Science, per Gary's
request.
- Planning the webpages for the Advanced Suspension group, per Calum's
request.
- Looking into the digital video setup.

(Lisa)
-With Ed C's help, I did a warranty return of the dead hard disk from electra.
-Set up ssh keys on most of the unix servers
-Moved pleione up to a visitor space in Millikan
-Spent some time with Larry on the foundry equipment.
-Modified the access permissions on ligo.
-Setup e-mail logging on acrux. The U of Washington imap/ipop puts a voluminous
amount of log info into the maillog.  Am looking at ways to reduce or eliminate
that.
-Testing out my automated patch script.  I'm going to begin running the patch
clusters tonight or tomorrow night.
-Started monthly backups.

(Larry)
-Finally, was able to spend some time working on the Gige installation. All of
the edge switches have been tested. All but two have been installed at their
assigned locations and have been tested. So far things are looking good. Along
the same line the preliminary tests on the new fiber installs went well. If all
the testing goes well the move over to the Gige backbone should start next
Friday.
-Checking out the h/w on a couple of SUN boxes. Appears one will need a reload
and the other will need a board replaced. These boxes are going to be used as
servers on the new Gige backbone to help distribute some of the services, and
ease the migration off of sirius.
-Resolved a couple of e-mail issues. It looks like we have a configuration that
can be used on all of the SUN boxes that will accommodate the different mail
tools being used.
-Resolved a couple of web server issues. Working on the logistics with Mike and
Veronica on a number of other web related issues. Setting up plans to migrate
some of the web services off of NT and over to Win2000.
-Worked on a number of procurements. Still quite a few to go.
-Updated some of the documentation and working on the updates for the 1-800
policy documentation.
-Worked with Ed C. on a couple of property issues and logistics for the LSC.
 

LIGO II/Advanced R&D (Sanders)

From: Mark Barton <mbarton@ligo.caltech.edu>

    This week I returned to debugging my Mathematica model of the
suspension and with the rederived and corrected version of the Matlab as
a guide I was able to weed out a couple of minor errors and get the
desired four-figure agreement in the mode frequencies. (As well as being
an important test for my model, this also greatly increases confidence in
the Matlab.) I adjusted the default values to better reflect the MIT quad
prototype and released it as v2.04 (<http://www.ligo.caltech.edu/
~mbarton/SUSmodels/asus4/>).

From: ctorrie <ctorrie@ligo.caltech.edu>

Prototype quadruple pendulum, MIT
(Norna Robertson, Mark Barton and Rich Mittleman)

Rich Mittleman at MIT has measured transfer functions and impulse responses of the quadruple pendulum in the yaw direction. Norna and I have shown that these agree very well with the model.

I now have a list of modifications for the quad at MIT, in order to solve the problem of the undamped pitch mode. Norna is back on Monday and Rich, Mark and I plan to discuss the changes then.
As I mentioned last week this will be able to be done in situ.

Suspensions

Janeen and I have been busy to re-organising the North area in the Synchrotron Lab. Janeen took a list of our questions with SOLIDWORKS to a drop in class on Friday. This was very beneficial and we plan to attend other classes in the future.

LASTi

Still working on completing a full set of drawings for the prototype LIGO-MC suspension. This has included close interaction with Eoin Elliffe and Russell Jones in Glasgow on parts for the coils.

40 Meter
Jay Heefner
- Preliminary design for the 40 Meter timing system has been completed and
drawings were issued for review. The small VME crate and the IRIG B distribution
amplifier for the system were ordered and due in the next few weeks.
- Drawings for the mode cleaner length and alignment controls are complete and
ready for cross connect list generation.
Sander Liu
- EO Shutter Controller - In the process of building three sets of circuit boards for the 40M. We are currently waiting for delivery of the high voltage power supplies from UltraVolt to finish repairing and testing two exciting units.

AdLIGO PSL
Peter King
Some minor teething problems have emerged with the wiring harness.
All the DAC function fine, along with the binary input and output channels.
However a problem exists with all the ADC channels, with the presence of a
~60mV offset on all channels, suggesting a possible grounding problem of
the cross connect.

Only one problem was encountered with the EPICS records database and that
was due to a typing mistake.  The MEDM screens were modified to reflect the
changes in the records.
