Weekly Report Highlights

LSC Issues (Saulson)

Note [pel]: the LSC Meeting scheduled to begin March 19, 2006 will be held in Hanford because of the potential difficulties related to lodging for large groups. All attendees should be sure to make reservations to and from and in the appropriate location.

The LIGO/TAMA S2 Burst paper is now published in Phys Rev D, vol. 72, article 122004 (2005).

LIGO Laboratory Administration (Lindquist)

STATUS OF LSC MOUs (Lloyd)

No report (vacation).

SITE TELECONFERENCE (Lindquist)

A site teleconference was held Thursday, January 4, 2006. The following issues were discussed:
Lodging in Livingston—Hotel rooms seem to be becoming available in the Livingston area. It should now be possible to support normal functions.
Science Education Center in Livingston—Progress seems slower than hoped. Steel work may not end until the end of February. A field change order has been issued to cover the costs related to the discovery of additional water connections.
Site Administrator Visits—Terry Gunter, Bonnie Wooley, Marie Woods will be visiting Caltech next week for rather extensive meetings with various administrative functions. A preliminary agenda has been prepared.
Property—We received a shipment this week of optics from Glasgow some of which are destined for Australia (possibly) and some of which will go to the sites after being worked (coated). This resulted in extensive discussion concerning how such material shipments are to be handled relative to customs regulations and the need to be aware of issues that can interfere with shipments and increase costs.
Livingston Gate—The vendor is currently fabricating the gate. Expect installation in about two weeks.

The list of assigned actions updated through December 01, 2005 (the last time that the list was updated) will be found Here.

SUBCONTRACTS MANAGEMENT (Jasnow, Salone)

>From: Gina Salone <gsalone@ligo.caltech.edu>

Nothing significant to report.

>From: Ed Jasnow <jasnow@ligo.caltech.edu>

The contract with Cangelosi - Ward for construction of the LLO Science Education Center has been modified to cover a field change order for a revision to the water connections. This resulted in an increase to the contract price of just under $7,000.
At this time, construction of the LLO SEC appears to be about three weeks behind schedule, primarily due to weather.
A preliminary agenda has been finalized for the visit of the three site administrators to Caltech on February 11 - 13.

LIGO Hanford Observatory (LHO) and Interferometer Operations (Raab)

Summary of Commissioning Activities at LIGO Hanford Observatory (compiled by M. Landry)

The LHO machines ran well over Christmas (~90% double coincidence), but fell back to more typical numbers during New Years (~80% double). Only H2 makes it's single IFO duty cycle goal, and given it takes on average H1 about 40m to return to science mode after unlocking, we have to extend H1 locks in order to meet the duty cycle goal. Below, find several duty-cycle related links.

Some elog highlights:

If only every day could be Christmas: check out the state vector from the early morning hours of Dec 25: smooth glassy sailing
weather in the Snoqualmie pass can impact Tuesday maintenance , stranding loads west of the Cascades
communication losses result in the control rooms not receiving GRB alarms (this is thought to happen fairly infrequently, about once every 2 weeks)
events of the recent Tuesday maintenance period were summarized
statistics on all three IFOs range and duty cycle numbers were updated
Recall that we had a stunt plane buzzing EY; the craft is in fact a biplane, and the owner and pilot identified as a physicist. Seriously.

4K IFO

glitchiness in the FSS is a concern and we are watching this, however it is not clear if it impacts the searches. More on FSS glitches here. plus, reducing the FSS ISS gain helped clear them up

2K IFO

while the 2k PSL laser power derivative was positive, this was later understood (thanks to the 40m lab) to be due to photodiode sensitivity to humidity
TCS laser glitches were observed to sometimes coincide with lock losses

CDS, DAQ

The CDS hanford1 disk system was upgraded. However, later in the week there were more problems with either the scsi devices on the bus, or the disk itself
The leap second: leap seconds were handled by new framebuilder code, which promptly crashed. Unrelated to the handling of a leap second, AWG failed on the year-rollover, knocking the IFOs out of lock. Conlog was upgraded to handle a leap second. On the LDAS side, as the frame builders were down, there was no problem handling the leap second (at LLO, raw and minute trend frames generated errors so no RDS frame was made for that time).
fb0 crashed due to raid disk problems, later restarted and trends returned

LIGO Livingston Observatory (LLO) and Interferometer Operations (Zucker)

L1 Interferometer (Frolov)

The 68% science duty cycle for the last two weeks is LLO's best since the start of S5, helped by the shortened construction work week. The interferometer BNS sensitivity remained around 10 Mpc during quiet times and 9 Mpc during seismically noisy times. The leap second transition was accomplished without noticeable problems, but data taking was nevertheless interrupted on the start on the new year due to the inability of the arbitrary waveform generator to change the year.

Other activities:

the IRIG-B signal for timing monitoring was connected
a new version of StochMon started
two weather stations (Y end and LVEA) have been reported working without software crashes for two weeks
During Tuesday maintenance the PSL smoke detector was found making the beeping sound due to low battery, which was audible in the LVEA. It is not known yet when the sound started, but no DARM glitches were reported on that day so far.
the initial testing of the ETMX driving chain electronics did not show non-linerity that could be responsible for up-converting the 12 Hz bounce mode motion into the detection band
The dropouts of the photon calibration line were reported. The cause of the dropouts is still under investigation.

Safety (R.Riesen)

New main gate to arrive within 3 weeks.
Setting up for installation of Retro-Reflective Photoeye gate closing interrupter for both the main and side gates.
Working on the annual LLO Safety Audit schedule.
Looking into the latest rash of after hour site "forced door" alarms. ### (MZ comment: weak door closers and high winds, not a crime spree!)
Ordered site camera fiber transmitter and receiver (replacement for inop units).
Performing internal LLO property audit.
Still waiting for the FM-200 fire system people for the requested alarm logic changes.
Found no safety concerns this reporting period.

LLO Outreach (Thacker)

finished 2nd draft of NSF annual report for LIGOSEC
completed preps for Feb 1st partnership meeting
continued preparations for teacher workshop commencing 1/27
provided LLO outreach visitor numbers pie chart
Revised the LLO tour guidelines and developed the tour providers list for two months

LLO SEC construction (Zucker)

Foundation excavation and concrete work is accelerating after a slow spell during the holidays. Grade beams are nearly complete and slab lifts are anticipated next week. Activity is still of a nature that prevents science operation during day shift hours.

CDS (Bogue)

At Caltech this week where I've had the great opportunity to sit down with various people and get a better understanding of how some of our software works.
Spent time troubleshooting a hard disk problem on procyon, the cds remote control machine at CIT.

CDS Code Development (Khan)

1) Diagnosing the LVEA Weather Station interface software. There was an occasional drop out of communication with the Weather Station data logger. I believe it is attributed to the serial port of the MV162-262 controller. I have replaced the controller to MV162-333 and so far it is behaving ok.

2) Developing a matlab program to display the DC values of the HEPI position and Geophone sensors. The software will display the motion of the pier in a three dimensional way as to visualize the pier motion over a period of time and also display statistics to show maximum and minimum displacement etc.

Computing and Network Security (Roddy)

Reinstalled the MRTG graphs. This used to be hosted on a machine that is no longer in service.
Working on getting flowtools going again. This package went away when the MRTG graphs went away. This was a valuable resource that was needed over the weekend and was not available.
Started working on migrating the user groups to a GID that is not in conflict with linux GIDs.
Received and posted a copy of the ligo-op web pages from Caltech. Dwayne or I will need to set up a permanent home for them within the next couple of weeks.
Usual round of updating snort signatures, checking logs, etc. I have been updating the signatures twice daily this week because of the Windows WMF flaw.
Lots of reading keeping up with the flaw mentioned above.

General Computing (Giardina)

working on creating a standard outreach PC image, almost complete
installed 6 DVD-RW/CD-RW drives in outreach PCs
usual user support questions, html assists

LDAS Admin (Giardina)

Brought wrong 3511 to MSR with Lisa. it was already installed in rack before I caught my mistake. swapped controller during downtime(non-locked state) on next day.
RMA'd 22 Maxtor disks
Power strip had tripped for nodes 55-62 Tuesday AM. resetting breaker on power strip fixed problem. expect it to fail completely soon, as it has already happened with two other strips.
Nodes 56, 95, and 131 had disk errors, replaced disks. have two more in warranty to RMA now.
Tapes ejected and shipped to CIT since last status update: LL0512, LL1060, LL1062, LL1064, LL1067, LL1069, LL1072, LL0791, LL1074, LL1077, LL1080, LL1082, LL1085, LL1086, LL1089
Tape LL1085 was reporting media error and only 3% full. SAMU is also reporting media errors on tapes LL0484, LL0676, LL0182, and LL0384 all currently in the library
Tapes imported to library since last status update: LL1060 - LL1089 and LL0790 - LL0819

Data Analysis (Yakushin)

1) Processed SG1_S5 MDC frames only to discover that they contain no injections at all in DARM-ERR channel. Keith Thorne is redoing SG1_S5 to correct the error.

2) Added a summary to the waveburst online page that contains various information obtained on all S5 data up to now in addition to reports generated daily.

3) Demonstrated that L1 generates much more low frequency glitches than H1 or H2. Trying to understand the cause and properties of those glitches.

40-Meter Interferometer (Weinstein)

IFO Commissioning

Osamu realigned the mode cleaner and re-commissionined the MC WFS system.
Rob exercised some configure scripts for locking the interferometer in various configurations, including one and two arms, Fabry-Perot Michelson, and short dual-recycled Michelson. In other words, everything except the full dual-recycled Fabry-Perot Michelson (which comes next).
Last night, Rob, Rana, Stefan and Matt got the IFO to fully lock, but it didn't hold long. They switched over to locking with the SRM is the wrong place (opposite side from optical spring) and it seemed to lock reasonably well. Lots of little things to tune up better.

PSL Re-commissioning

Steve measured the throughput of the PSL beam through the PMC (a dismal 58%; we've seen it above 85%) and total throughput from MOPA to periscope is only 42%. Still, it'll do for now.
Rana spent some time optimizing the PSL frequency stabilization servo.
Steve and Rana redid the layout of the PMC reflected path to give enough light onto the RFPD to get the servo bandwidth up to snuff (about 1.5 kHz). Steve installed a new ccd camera in the PMC reflected beamline and re-installed the SP camera. Bob will wire the new camera into the video switch.
Ben and Rana made some modifications to the PMC board, tuning some notches. He also re-set the demod phase. The PMC servo bandwidth is now ~ 8 kHz with plenty of phase margin.
Our Mach Zehnder appears to be working well with the new MOPA laser, but throughput appears to be a bit low. We might want to tune up the servo board. But Rana is instead thinking about eliminating the Mach Zehnder, and instead developing a synthesized signal to send into a single broadband Pockels cell which will produce our two pairs of sidebands without generating sidebands on the sidebands (or, only generating very small AM sidebands on sidebands).
Rana noted that our mode cleaner servo board is of an undocumented vintage, and he had a hard time figuring out what it was doing. He measured the OLG, and found a UGF of 22 kHz, which is pretty low. He decided to await a new Siggian MC servo board, which LHO will ship to us next week.

IFO Modeling

Monica has used her e2e model to produce a transfer function that shows a clear optical spring peak, although it's at a somewhat higher frequency than expected or seen.
Osamu continues to develop his e2e model. He is implementing the 40m seismic noise and stacks, and is developing a detailed model of the controls, including all the analog and digital filtering.

DC Detection Development

Mike Gerfen finished machining the output mode cleaner (OMC) body, out of copper. It's beautiful. A few minor fixes to the mirror bezels are in progress.
Ben is continuing to work on the Solidworks assembly of the DCPD mount design. He talked to Rick at the machine shop, and he said that the fabrication should go relatively easily.
Bob has tested the resistors that Ben and Rana plan on using for the DC photodiode electronics; they are safe for use in high vacuum.
Ben plans on testing the DC photodiode circuit that he and Rana developed, in the coming week.
Rana and Rob will draw up a detailed scheme for length and alignment control of the DC readout system, and begin ordering parts.
Sam and Dan are beginning to build a prototype alignment servo system for the DC readout beamline, using our two in-vac Piezo-Jena steering mirrors as actuators. They assembled the mirrors (without breaking the PZT stacks!!) and wired up one degree of freedom to a spare IO pzt steering mirror board, and verified that it works.
Sam is thinking about the alignment servo design. It's not clear whether QPDs or dithering will be used to sense the beam position/angle going into the output mode cleaner. Because any beam jitter going in to the OMC translates into transmitted intensity noise and thus GW signal noise, Sam is aiming to develop a high-bandwidth system.
Dan and Mike Gerfen are fixing several small problems with the output mode matching telescope machined parts.
Steve will install a "dirty" picomotor into the output mode matching telescope and test the mechanical resonances with his phonograph needle apparatus.
The breadboard for pre-alignment of the in-vac DC readout beamline is in the shop, expect it in a week.

Electronics, Controls, Computers

Alex Ivanov has succeeded in recovering our 3.7 years of minute trend frames from the failed RAID array, and has made them available once again to dataviewer. Next step is to get a regular and reliable backup system. We hope to be able to push the data to CACR archives in Powell-Booth, with help from Stuart and Dan.
Ben has begun the tuning of some double-demod RFPDs for the 40m lab.
Larry installed non-ligo-specific GC software onto a new Blade 1500 for use as a new operator workstation (op540m); we'll put it into service by the end of the week.
Rana added a bunch of DAQ indicators into frame channels.
Rana reworked the DAQ interface board which routes signals from the PSL FSS, PMC and ISS systems to the data acquisition system. He stuffed it with the appropriate amps and filters for all the various signals. The table-top ISS servo board is rev 0.1, needs some mods to get into DAQ. Rana modified the ini files to get the right signals into the frames, correctly labeled.

Lab Infrastructure

After the rains, Steve reports that there were NO roof leaks. There are, however, plenty of ants.

Thermal Noise Interferometer (Black)

Nothing significant to report this week.

LASTI (Ottaway)

No report.

Data Analysis and Computing (Lazzarini)

Simulation and Modeling (Bhawal)

Advanced LIGO mirror size

(Hiro) Yi Pin delivered a new result with the curvature error is +-1m and +-2m. The SNR is very sensitive to the curvature error and the (non) degeneracy of the recycling cavity configuration. We need to use a tool like FFT to conclude any definitive answer, but it can be that the requirements could be very stringent.

modeler

(Hiro) The statespace module is very slow and the ABCD matrices sizes are large. An optimization is being investigated using only part of the matrices which actually contribute to the answer.

Data Analysis Activities (Lazzarini)

Chatterji:

Spent 9 days as a SciMon at LHO
Performed an in-situ calibration of coil magnetometers installed in the remote vault at LHO.
Drafting report on anomalous detector behavior from Dec 9 to Dec 12 as part of the glitch and detector characterization group: http://ldas-pcdev1.ligo.caltech.edu/~shourov/S5/glitch/Shift_20051209_20051212_SC.html
At GWDAW10, I gave a talk describing LSC burst group data conditioning activities. I also presented a poster on the current status of the Q Pipeline.
I Performed follow-up study on calibration line glitches in H1 on 18 Dec 2005 (hanging awg process) and L1 on 25 Dec 2005 (single sample dropout):

http://ldas-pcdev1.ligo.caltech.edu/~shourov/2005DEC18_calibration/

http://ldas-pcdev1.ligo.caltech.edu/~shourov/2005DEC25_calibration/

I am continuing to develop a tool to automatically scan large numbers of channels for statistically significant content around times of interest. The tool has been extended to display both time-series data and time-frequency spectrograms with and without data conditioning applied.
I am working to automate the postprocessing of the online S5 Q Pipeline analysis.
Regenerating triggers for the LIGO/Virgo joint data analysis working group to target a new agreed upon signal space.

Mendell:

I have finished adding new options to the SFT generation code. These include:

a. Options to write version 2 SFTs, using LALWriteSFT2file and the specification given in T040164-01. This includes options for the comment field for the SFT header, and the misc. desc. field of the file name.

b. Options to apply various windows with an overlap factor. The default is to use the tukey window function, as defined in Matlab, and no overlap. The other window options are to use the tukey-like window defined in lalapps/src/pulsar/make_sfts.c and to Hann window, as defined in Matlab (which can be used with a 50% overlap).

c. Options to created the output SFT directories on the fly, based on GPS time. This works identically to the way RDS directories get named, will allow the code to run through-out S5 without putting too many files in one directory.

d. One can set the start freq. and freq. band from the command line (defaults are the usual f0 = 48 Hz, band = 2000 Hz).

Previous options already included were high pass filtering, use of double vs. single precision, the channel name, and preprocessor flags to check memory use and print example values.

I next plan validate the version 2 SFTs, and start generating them from hoft, and then publish these SFTs. The code is in lalapps:

lalapps/src/pulsar/MakeSFTs/MakeSFTs.c

lalapps/src/pulsar/MakeSFTs/scripts/MakeSFTDAG

In the meantime, 1800 s SFTs continue to be generated from uncalibrated DARM_ERR, with the output on ldas-grid at LHO and LLO respectively under:

/cluster/pulsar/S5H1_1800s_DARM_ERRNoCal_v1SFTs/

/cluster/pulsar/S5L1_1800s_DARM_ERRNoCal_v1SFTs/

Shawhan:

Revamped the GWIstat web page at http://www.ldas- sw.ligo.caltech.edu/ligotools/runtools/gwistat/ .
Maintained conlog code at the sites.
Worked on burst hardware injections

Yakushin:

1) Processed SG1_S5 MDC frames only to discover that they contain no injections at all in DARM-ERR channel. Keith Thorne is redoing SG1_S5 to correct the error.

2) Added a summary to the waveburst online page that contains various information obtained on all S5 data up to now in addition to reports generated daily.

3) Demonstrated that L1 generates much more low frequency glitches than H1 or H2. Trying to understand the cause and properties of those glitches.

LIGO Data Analysis System

Software Systems (Blackburn)

LDAS

Continued to focus on 64-bit compilation for Solaris. As of this week, all unit tests now pass. Several of the integrated system tests work (ilwd to ligolw conversion, ligolw to ilwd conversion and several createRDS to mention a few). Of the integrated system tests that do not work the common failure is with the transmission of data via the data sockets. More investigation is required to figure diagnose the cause of the problem. The pkgbuilder rules for OpenSSL and Apache were modified to embed the runpath for the 64-bit libraries. This eliminates the need for LD_LIBRARY_PATH to include the 64-bit library directories.

It was discovered this week that FrVerify complained about frames spanning the addition of the January 1, 2006 leap second addition. The code has been corrected and will be available with the next release of LDAS.

The open PR (2962) to address failure to display more than one API's memory graph has been closed

Discovered that the TCLGLOBUS channels sometimes do not invoke the fileevent and sends block commands to the controlMonitorAPI's server. A PR has been opened.

The All-Users-Command test failure to detect failing jobs (PR 2969) has now been fixed and closed.

Performed system and integration tests on LDAS development version 1.8.48. Found a few issues with the test programs which have now been fixed.

TCLGLOBUS

Worked on PR #44 where LDAS managerAPI accepts the new connection but failed to get fileevent triggered using XIO-based Tcl channel. This problem was discovered when running managerAPI on ldas-dev.ligo.caltech.edu. I have a fix for this problem and it's caused by incorrect implementation when allocating a new handle for a new client.

Worked on service credentials within LDAS. Mary has tested the code on ldas-suntest3.ligo.caltech.edu and it's working. I need to work some more code implementation to handle a default location of service credentials.

GRID COMPUTING

Received fix from Duncan Brown related to a patch for supporting L4 data with Inspiral pipe. Will be validating this fix with Level 4 data.

Yum updated Fedora Core 4 packages on osg-itb and osg-itb-se.

Installed OSG 0.3.4 release on osg-itb and osg-itb-se. Validated the osg-itb installation with site-verify gridex and gridcat.

Installed osg-client form OSG 0.3.4 on osg-itb-se and setup up vds tools. Attempted to run Level 3 data set (38 GB) used to validate OSG 0.3.1.300 of the 724 DAG nodes failed. More testing will be needed to determine if problems are in the OSG 0.3.4 osg-client package or related to FC4 as this is the first time the osg-client package has been tested on FC4.

The OSG Council held its second "Town Meeting" to discuss with the Executive Board Director candidates their positions on issues of concern to the council. The earlier concerns about the focus being to LHC specific have been mostly addressed by the candidates. Shortly after the meeting it was learned that only one candidate intends to run on the ballot.

Hardware Systems (Anderson)

Caltech

(Dan Kozak)

Still pursuing the question of why some files are not being archived for a very long time and then only with human intervention. Mostly just doing the manual intervention and hoping that the spliting out of / archive/home to it's own filesystem (with it's own archive parameters) will fix the problem.
Did the standard tape exporting, shipping, ingesting. Now have the admins at the sites are running the tape eject script themselves.
Released old data pinned to disk at LHO (Greg had noticed that / archive was getting full).
Installed new blade in CIT's FC switch and provided instructions to the admins at the sites how to do the same.
Made LLO only use 4 (of 6) tape drives for staging (user requests were taking over all the drives and causing archiving to stop).
Twice identified publishing scripts dying, but in both cases Ben had to make changes before they could be restarted.
Installed 2 new 3511s at CIT, have been working on setting them up. Before we got a second controler from LHO, experimented with making a single 10Tb+ LUN between the two boxes (which worked as far as the 3511 was concerned, tho' it took the better part of a day to build).
Discovered that Sol10 doesn't see new FC devices without a reboot. Submitting to Sun.
Rerouted internal GigE fibre for ldas-cit & ldas-archive so they use the switch in Synchrotron (not Millikan).

(Phil Ehrens)

Upgraded LDAS-test beowulf, metaserver, and datacon boxes to Fedora Core 4.
Upgraded ldas-gridmon to Fedora Core 4.
Finished configuring LDAS on the LDAS-CIT system.
Upgraded ldas-test gateway to Solaris 10 Update 1.
Upgrade of dataserver-test failed due to broken dvd drive. Currently investigating "jumpstart" and pxe/dhcp based network install schemes.

The addition of the Dec 31 2005 23:59:60 UTC leap second caused minor issues with frame generation. At LLO these frames span Dec 31 2005 23:59:60 UTC:

/archive/frames/S5/L0/LLO/L-R-8201/L-R-820108800-32.gwf

/archive/frames/trend/second-trend/LLO/L-T-820/L-T-820108800-60.gwf

/archive/frames/trend/minute-trend/LLO/L-M-82/L-M-820108800-3600.gwf

and have ULeapS set to 32. At LHO this frame spans Dec 31 2005 23:59:60 UTC:

/archive/frames/trend/minute-trend/LHO/H-M-82/H-M-820108800-3600.gwf

and has ULeapS set to 33. (No other DAQ frames were generated at LHO that span this time.) However, in all cases frames that span Dec 31 2005 23:59:60 UTC have a somewhat ambiguous leap second, since the change in leap seconds occurred during the frame.

No RDS was generated for the times that span the leap second addition.
We have decided to mark these times with a NO_RDS data quality flag.
Otherwise, S5 Data archiving, publishing, and RDS generation continues to run smoothly, and monitoring of these has allowed sys admins to correct minor problems as they arise with no loss of data other than at times when both framebuilders are down.

(Ben Johnson)

Currently publishing h(t) data at both sites. The scripts use diskcacheAPI for file discovery, and a bit of modification to the metadata and PFN generation routines.
Fixed rls-server crash at LLO. Most of my scripts there handled the crash as intended (caught exception, exited). But one had an unhandled exception. I need to do more work to make the scripts more robust.
Replaced fb0's 3510 with a new 3511 (single RAID controller unit). The unit was set up with a 10+1 RAID plus a global spare giving 4.5TB of space for /fb0_frames. The firmware is still at 4.11I and needs to be upgraded to 4.13.
I have tweaked the webserver at LHO (ldas-jobs) to meet user requirements. Some users are finding it very useful.

Rebuilding laptop o/s after fatal harddrive crash
Worked with Mike P. to setup VPN connection from MIT
Installing Solaris 10 on test box(s)
Will attempt to contact sun regarding LDAP questions related to client side certificates.

LLO:

(Dwayne)

Working on creating a standard outreach PC image, almost complete
Installed 6 DVD-RW/CD-RW drives in outreach PCs
Usual user support questions, html assists

(Shannon)

Reinstalled the MRTG graphs. This used to be hosted on a machine that is no longer in service.
Working on getting flowtools going again. This package went away when the MRTG graphs went away. This was a valuable resource that was needed over the weekend and was not available.
Started working on migrating the user groups to a GID that is not in conflict with Linux GIDs.
Received and posted a copy of the LIGO-op web pages from Caltech. Dwayne or I will need to set up a permanent home for them within the next couple of weeks.
Usual round of updating snort signatures, checking logs, etc. I have been updating the signatures twice daily this week because of the Windows WMF flaw.
Lots of reading keeping up with the flaw mentioned above.

LHO

(Christine)

Configured the LAN main switch for a second vlan for the new phone system being installed this week. Just set up 24 ports on the new vlan to test with. Also tried to set up two ports for testing with auxiliary vlans which allow one port to be assigned to two vlans, one designated as voice and one as data.
Testing of the backup network circuit has been postponed until 1/10/06. I may need to replace the media converters between LIGO and PNNL from 10 Mbs to 100 Mbs converters in order to be compatible with the ESnet Juniper router.

CIT

(Veronica)

LIGO: Ongoing troubleshooting of the web server migration. End-of-year maintenance/changes. Added a 2006 search category to the DCC database. Roster database update. Mailing lists update. Updates to the LIGO website. Christian and I went over a new webcam package with better resolution, which is being considered for use. Addressed an issue regarding the terms of use of an image owned by the Caltech Archives for an educational project, per a user request. Updates to the MIT LIGO website. User support.
LSC: Updates to the database of LSC-reviewed documents. Updates to the Observational Results webpage. Posted a couple of late talks to the November meeting website. Updates of the LSC-related mailing lists.
CaJAGWR: Website updates. Taped and compressed the video of the last seminar, posted a stream pointer at the website.

(Mike)

DCC: Spent most of this week reloading Server 2003 for new DCC database. Going with the new configuration on how to implement these services using SYNERGY software is a lot of work. Running SQL server 2002 on one server as our database storage and then running the SYNERGY, plus ColdFusion server 5.0 on an additional server is a challenge. I have been working with SYNERGY's tech support + engineers on how to get this working; we are almost there but we are still having some problems that need to be resolve. This is an on going project.
PRIMAVERA: Worked on this setting up a user to connect here at Caltech to view and add data to the primavera database.
Testing of unofficial Microsoft WMF patch: I tested this patch on XP, Win2000, 2000 server, and 2003 server, and it seems not to affect these Operating Systems, including all GC software. I have loaded this patch on our NTSRV's. We are also loading this patch on our administrative PC's. (Important) The unofficial patch must be un-installed before you install the Microsoft patch, which is scheduled to release on Tuesday the 10th.
Other misc. user support.

(Christian)

Created a backup of Julie Hiroto's workstation. Also, I replaced the toner cartridges on local printer.
Upgraded Gina from Microsoft Office 2000 to 2003.
Replaced toner cartridges on HP 5500 printer.
Created a backup of Irene Baldon's workstation.
Worked on automating the installation of a emergency Microsoft patch from a third party. Microsoft is now releasing a patch earlier than previously announced so the automation script no longer needs to be distributed. Other misc.: Continued onsite software/phone support.

(Larry)

Placed a number of purchases. Cables and Misc. items as well as a maintenance contract for the LDAS group. A number of misc. items for the GC group. Also, worked a couple of the supply items for the bus. group.
Installed updated licenses for a number of packages that expired over the holiday period.
Replaced the CIT LIGO web server with a newer unit. The timing worked out in that the disk on the older server went bad a few days later. The new server now has all of the same functionality as that of the old one. We are now working on modifications to improve performance and security on the unit.
Installed various s/w pkgs. on one of the 40M servers.
Updated one of the Engineering sandbox servers.
Setup a number of new calendar sets. The listings for the conference rooms will be moved to the newer calendars.
Assisted/Assisting Mike on the setup of the new DCC systems.
Assisted a large number of users that had problems which turned out to be typo's. It must be something in the air, usually it is just one or two a week but over the holiday period it has been more like a dozen a week.
Worked a number of server related issues. Mostly moving accounts around to get more disk space for the active users.
Did the monthly backups for the home accounts. Now working on the backups of the server OS directories.

Advanced LIGO Project Management

from Carol Wilkinson

Preparation for NSF Baseline Review

The advanced LIGO project office has started preparing for the upcoming NSF review of the Advanced LIGO Project final baseline. This review is expected to take place in May 2006 and is the next step in obtaining approval for funding. Preparation entails producing the final cost, schedule, and funding profiles as well as the Project Execution Plan, Personnel Transition Plan, and other documents. The project office will be asking for cooperation and support from various members of LIGO and the LSC as we tackle the impressive work load ahead of us.

Suspension

From: Janeen Romie romie_j@ligo.caltech.edu

Nergis's fixtures were delivered to her in December. Ric/Physics Shop has finished the ECD parts for the controls prototype. They are fixtures, so only need Class B cleaning and baking. The ECD parts themselves have been fabricated a while ago. Working on the noise prototype ETM test mass drawing with Gari and Dennis. Coordinating with Brian O'Reilly on his visit to LASTI for quad installation. Working on actions from Carol and Dwight about staffing and schedules.

Core Optics

From: Bill Kells <kells@ligo.caltech.edu>

I have accelerated the calculation of PI effects for "all HTMs at once". This issue has been mulled over for about 6 months now. We had seen a way to exactly calculate it within the FFT scope. But now, with Biplab Bharwal leaving up, I have taken up the reigns (and his program !) to actually start this. The present "missing link" is the lack of available acoustic mode surface maps. Also, I am cotinuing with design considerations of an optimized "stable" SRC/PRC for AdL. In this a major consideration immerging is whether both the SRC and PRC ought to be "stabilized" , or only the SRC.

Pre-Stabilized Laser

From: Peter King pking@ligo.caltech.edu

I have begun analyzing the data obtained from the high power laser. The broad peak seen in the Innolight NPRO intensity noise is present in the 12-W master laser output with the noise eater on. In retrospect it would have been handy to have performed the measurements beyond 100 kHz.

Of the three laser heads that transfer functions measurements were performed, two of the laser heads appeared similar. The reason for the discrepancy with the third laser head is unknown at this time. I assumed that all diodes were of the same vintage but will have to check with LZH.

Auxiliary Optics

From: Michael Smith <smith@ligo.caltech.edu>

Solid Works Vertex Model:

I have drawn beam envelopes at the 100ppm diameter for the main beam, the PO beams, and the ghost beams that are to be dumped, and am in the process of adding baffles for additional primary ghost beams.

I have added an output mode-matching telescope (OMMT), a Faraday isolator, and a "straw-man" 3-mirror OMC (LIGO1 PMC).

Other Laboratory R&D

From: Riccardo DeSalvo desalvo@ligo.caltech.edu

Marco's weekly (04 Jan):

Working on some issues of the data taken this summer from the Mesa beam Fabry-Perot cavity prototype. I'm keeping in touch with John Miller to discuss about the silt sensitivity results and to discuss about the paper that I'm already writing.

Yumei

Working on a solid works representation of HAM SAS. Starting to apply ANSYS on some parts.

Alberto

Writing paper on Center of Percussion Point compensation in GAS filters.
