Summary of Commissioning Activities at LIGO Hanford Observatory (Landry)
After a rocky start, the E11 run finished quite smoothly. New front-end
code installed
late Thursday 18th in the end stations did indeed fix H1's locking problems,
and the machine ran at about 7Mpc with a duty cycle of 71% for the remainder of
the run. The turning
off of a problematic AS2I servo (likely photodiode and/or electronic
saturation) immediately improved H2's binary inspiral range by 50% to
1.5Mpc. H2 duty cycle from this point was a similar 70%. Data from
the run were archived
and reduced. Thanks to those who visited LHO and helped make the run
happen.
Some commisioning highlights from the past week and a half are:
4K IFO
2K IFO
DAQ
Outreach (D. Ingram)
Dale Ingram recently visited two
MESA classrooms at Pasco High School. MESA supports math and science
achievement in underserved student populations. Fred Raab and Dale
hosted WSU Tri-Cities Chancellor Larry James and Columbia Basin College
President Lee Thornton for a visit on
12/1.

Rolf Bork reporting
- Alex is still at LHO this week.
- The first three 2.2GHz VME processors w/3 PMC slots are
due to arrive today. Two will be tested and shipped to LHO and one will remain
here for code development/testing. I have ported the LSC software to run on
these processors and will begin testing when the units arrive. This code will
be then run and tested on the LHO4k early next week.
- Along with Daniel and Alex at LHO, performed some more
timing tests on the FDI DAC modules. The modules consistently come up synced
within 2usec of the GPS 1pps. This is probably fine, however, after contacting
the factory, we found out that we don't have any easy options for changing this
timing, if we so desired. First, applying our own 16KHz sample pulse to
hardware set the timing will not work. Though their manual states this is an
option, it turns out that it is not. They would have to change their input
signal coupling and reprogram their firmware.
- Starting to work on providing LSC signals to HEPI
controllers at the LLO corner station. This will require the purchase of two
additional reflected memory (RFM) network modules (~$4K) to make the physical
network connection. It turns out that we still have a spare network port on the
RFM hub in the mass storage room to make the connection so no other hardware
rearrangements are necessary.
Rich Abbott reporting
Jay Heefner reporting
Fiber Optic Timing Link (Sander)
=========================
- The transmitter and receiver board layouts are done.
Sander will send the files to the group for review.
- The fanout board layout is being checked by Sander and
appears to have a few problems. He will fix them this week.
- All files should be out for review by the end of the week.
Timing System Redesign (Flavio)
=======================
- Rolf is drafting up a requirements document.
Anti-Image Filters (Todd)
========================
- 5 sent to LLO. 7 more in assembly.
40 Meter (Ben/Jay)
==============================
- The satellite amp from MC1 seemed to have failed, but when
tested in the shop it is OK. It will be tried again in the system in an effort
to find the problem.
- Jay has been working on the ISS. There were a few
problems. The light has a large 3.707 MHz signal on it. It is the beat between
the 29.5MHz and the 33MHz. This signal was causing saturation in the
amplifiers. A notch removed the signal. The high gain output stages also had
large offsets which were causing saturation. The offsets have been trimmed and
the system is working much better. Transfer function and noise measurements
will be posted in the elog.
- A new wireless network has been installed. The higher rate
cards and hub work much better.
- The problem with the alarm handler has been found. Most of
the database records have incorrect entries for the HSV. LSV, HHSV and LLSV
fields. These will be fixed as time permits.
LSC PD Redesign (Ben)
===========================
- The first board is being tested.
- The boxes are being milled. The first article has been
received and looks good.
ISS (Flavio)
=============================
- Two more units for LHO are being tested per the originalb
design and test procedure.
- Working will LHO to track possible changes.
- Will stuff at least 3 more boards, 2 for LLO and 1 for the
40M.
TCS Chiller (Mohana)
==============================
- First board being tested in the chassis.
- 2 more boards being stuffed.
TNI (Jay)
=============================
- Need to order and PC and PCI cards for epics controls.
Right now they are borrowing our development system.
Elect Shop (Todd)
=============================
- Dave is fixing the GPS clock drivers sent back from LASTI.
- Building 50 each 4 pin lemo cables for LHO. We need more
cable to complete.

PeterKing
A problem with the power op-amp inside the 21.5 MHz
photodetector was fixed. The 21.5 MHz frequency reference card had a
problem with one of the biasing inductors causing the local oscillator output
to drop. After much fiddling around and hunting for missing items, the
PSL is up and running.
Ken Mailand
Im completing 5 laser chiller assemblies to supply the
LHO and LLO sites. One unit shipped to LHO, Phil Willems and Cheryl are testing
the system this week.
Mike Smith
I am in the process of laying out the H1 IFO optical beam
paths using Zemax.
Discussions are being held with Paolo La Penna of VIRGO for
him to visit LIGO in January for collaboration on the proposed VIRGO parabolic
input mode-matching telescope, and possibly collaboration on a TCS for VIRGO.

Simulation and Modeling
(Bhawal)
Weekly Physics Meeting
---------------------------------------
Sany Yoshida from Southern Louisiana University presented results from SimLIGO
simulation in which they have included Mode-Matching Telescopes (MMT) in Input
Optics. They studied signals (at Dark port and in transmitted light through
X-arm) due to motion in MMTs. Hiro discussed the bright Michelson fringe data
under two different thermal states of the interferometer. Keita from LHO also
joined us in that discussion. At the end Hiro discussed his latest plots for
signals before and after the output mode cleaner.
Presentations
----------------------------
Hiro Gave a LIGO science seminar on November 30th.
www.ligo.caltech.edu/~hiro/G040514-00-E.pdf
Commissioning support
----------------------------------------
(Matt) Worked on commissioning software tools. In particular, I'm working
to develop a tool for automated noise hunting. This tool will look for
coherent and incoherent noise increases in AS_Q coincident with noise injection
in another channel.
(Hiro) Finally got a bright Michelson fringe data from Luca and has started
analyzing results. Worked with Rana to study the relation of OpticalGain vs
Spob. The agreements are very good. OpticalGain ~ Spob^0.85 was the result from
measurements. Naively speaking, it should be Spob^0.5 (error signal = sideband
* carrier and Spob = sideband^2). I am going to find the source of extra Spob
dependence.
(Biplab) PhaseCamera Data analysis: In order to have more understanding on the
origin of astigmatism, repeated the modal expansion considering rotation angle
(in transverse plane) of the observed elliptical beam profiles as a free
parameter in this fitting. Beam-profiles in some of the thermal compensation
states (e.g. No heating, AX330_CY75, AX600_CY75 etc) are showing reproducible
rotation angle, while in some others, this angle varies a lot. For comparison,
also analyzing data by averaging over several tens of measurements taken on a
particular day under certain thermal state.
e2e simulation of 40m Interferometer
----------------------------------------
(Monica) Differential demodulation and double demodulation (with demodulators
in parallel) have been implemented in the 40m package. Mach-Zehnder residual
phase noise is under test: transfer functions between MZ steering mirror and
40m asymmetric port and between L- degree of freedom and 40m asymmetric port
are in progress to get the estimation of noise.
Code maintenance
----------------------------
(Melody)
Finished modifying the E2E scripts to move the auxiliary scripts to the
(platform dependent) build directories. Also modified the scripts
to set 64-bit flags when building in the AMD64 machines.
Working in speeding up the dynamic link process in the modeler.
Alfi
----------------
(Bruce)
- Working on bundler generated connections to be passed to the modeler.
- Implementing bundler output rename.
- Fixing problem with port renames which are not being propogated to
derived nodes properly.
Data Analysis Activities (Lazzarini)
LIGO Data Analysis System
Mendell:
The final Version 2 SFT specification adopted by the CW group following
recommendations of the SCB has been added to the DCC: LIGO-T040164-01-Z.
Comparisons between the output of the StackSlide, PowerFlux, and Hough codes
continue to further validate these codes and eventually benchmark their speed
and efficieny of detection. An improved comparison between StackSlide and
PowerFlux has been added to the password protected S2 investigations page:
http://www.lsc-group.phys.uwm.edu/cgi-bin/enote.pl?
nb=puls2stackslide&action=view&page=18.
A more detailed comparison of StackSlide and Hough is underway.
An "E11 FAQ" link to summarize online analysis and data access for
E11 has been added to the DASWG online project web page:
http://www.lsc-group.phys.uwm.edu/daswg/projects/online.html,
which
links to
http://www.lsc-group.phys.uwm.edu/daswg/projects/online/E11FAQ.html.
This page also links to the official E11 home page
http://blue.ligo-wa.caltech.edu/engrun/E11/index.html
and vice versa.
Shawhan:
* Did a check of the total observation time for the S2 MACHO inspiral search.
* Tracked down a bug in the conlog query code reported by Hugh Radkins.
(Appeared when asking for changes over a time interval which spanned one or
more crate reboots.)
* Added a new feature to ivana, to output a list of veto triggers which did not
veto any event candidates.
* Created a new LIGOtools utility called 'segexpr' which evaluates logical
combinations of segment lists in files; will appear in a future release of the
'segments' package.
* Performed calculations of frequentist coverage for the S2 burst analysis with
a model for conditional analysis procedure.
Sutton:
I've continued work for the LIGO-TAMA review, mainly examining the
characteristics of LIGO and TAMA triggers. Much of this has been done
with Erik Katsavounidis, who pointed out several features that I've been investigating
one-by-one. Most of the odd behaviour Erik noted is now understood,
and I'm hopeful of a favourable verdict form the reviewers next week.
In other business: At the request of Stefan Ballmer, I got SenseMonitor
ready to run at LLO (with lots of help from Ballmer, Gonzalez, and
Zweizig). SenseMonitor is waiting for the excitation channel to become
available at LLO so it can compute ranges. I'm also trying to get
TFClusters running again for the Barkhausen noise test (with Willems); I'm
having trouble because the file systems at CIT have been re-arranged since last
used TFClusters and the old job scripts no longer work.
Yakushin:
1) Preparing for GWDAW-9 presentation.
2) Running single-ifo version of waveburst and plotting standard efficiency
curves on simulated LIGO-VIRGO data on Michele's request, to be used in his
GWDAW-9 talk.
3) Generated triggers on E11 data using single-ifo version of waveburst.
4) On request by reviewers running v5 waveburst with time-frequency
multiresolution turned off to prove that this is the major source of the
improvements in sensitivity at low frequencies.
5) Participating innumerous telecons that review S2 and S3 presentations at
GWDAW-9.
Lazzarini:
Worked with Romano on the stochastic analysis post-processing scripts to clean
them up in preparation for our code review for the S2/S3 results. Completed
stitching together ~ 40000 1-minute spectra into a 601x40000 pixel
time-frequency map of the stochastic cross-correlation spectra for all of S3
for H1-L1 and H1-H2.
Brown:
Participated in inspiral review telecon which reviewed the matlab scripts used
in the S2 analysis. Continued to work on the S2 MACHO paper and some extra
tests requested by the review committee. The final MACHO result has been
approved for presentation at GWDAW.
Started looking at the results of the E11 online inspiral run. While the online
run wasn't perfect, it went very well, considering our goals. Will work with
Greg Medell and Kipp Cannon on debugging the issues found.
Continued work on InspiralMon, a tool for viewing the results of the inspiral
search in the observatory control rooms. This is a DMT monitor that generates
summary plots of the inspiral jobs that run online under Condor at the sites. A
screen shot of the prototype is in the inspiral group notebook at
http://www.lsc-group.phys.uwm.edu/cgi-bin/enote.pl?
nb=s3news&action=view&page=11
InspiralMon needs some more work to make it more robust, but it should be able
to give near realtime astrophysical feedback to the operators and commissioning
team in the control room using an interface that they are familiar with
(DMTviewer). The goal is to have InspiralMon running in the control room as
soon as possible so people are familiar with it as a figure of merit before E12
and S4.
Attended the griphynligo face to face at ISI to plan future development of
running LSC codes on the Grid under Pegasus. Released the new Grid LSC User
Environment package (glue).
Software Systems (Blackburn)
LDAS:
The generation of RDS frames during the engineering run was very successful in
the generation of the longer frame files and longer frames within the frame
files. No errors occurred in this process.
The frameAPI and frameCPP libraries have been modified to allow extraction of a
subset of an FrAdcData structure and FrVect structure. This is needed by the
createRDS command to allow for proper creation of short frames. Extraction of a
subset of an FrProcData structure still needs to be done.
Modified configure.in and Makefile.am files to get LDAS's version of LJrun
installed.
Removed resource variable (dbuser) and password from db2utils; Now obtaining
this information from metadataAPI.
Modified database exception tests, insertion tests and putStandalone tests to
reflect this change to the resource file.
Updated controlMonitor Jobs Tcl code to clear database selected by job
command when running putStandalone or putMetadata jobs.
Improved deletion script del_db_process.tcl sql commands to speed up clearing
of database for putStandAlone or putMetaData jobs.
Updates for PR 2747 for the metaDataAPI, remove ::dbname from metadataAPI and
use ::DATABASE_NAME for source of default dataabase so it can be updated via
cmonClient without reboot of metadataAPI.
Ran LDAS system tests for frame functions on dev Monday to verify Ed's changes.
Created LJrun package for ldas from ligotools and modify test scripts to use
that instead of ligotools. cvs LJrun files.
Most of the software developers worked with the hardware group to install hard
drives on the CIT cluster.
Added new feature to Running Jobs Status Page to indicate suspension of jobs by
the system do to internal reasons, e.g., restart of API.
TCL/Globus:
Created framework for documentation of the exposed TCL commands (User's Guide).
Started working on a framework for documenting the Developer's Guide.
Completed the SWIG wrapping of XIO functions along with TCL test cases to
exercise these newly wrapped functions. This brings the total wrapped functions
to 31. Four test cases from previously wrapped functions are still under
development.
Completed first draft of TclGlobus user documentation on how to use the XIO
functions (based on ROBODoc documentation generation tool and the framework
mentioned above).

(Dan Kozak)
* Restarted RLS after Thanksgiving weekend crash. Have continued to
monitor it.
* Continued cleanup of 16k block tapes in SAM.
* Participated in cluster upgrade.
* Workedwith STK to remove the LIGO 9940A drives and the CACR 9940A and 9840B
drives from the LIGO silo.
* Made a first attempt at moving acsls.cacr.caltech.edu to a private
network. It didn't succeed, but we learned enough that we think we can
make it work.
(Al Wilson)
* Installed new 200g drives into ALL 210 CIT nodes.
* Moved machines around in 215 sync.
(Stuart Anderson)
* Successfully replaced the LDAS-CIT cluster core switch with a newer
larger unit.
* Moved ldas-pcdev2 to a direct connection to the CIT cluster.
* Helped install 210 additional 200GB drives in the CIT cluster.
MIT

(Keith Bayer)
* Handled water leak in ldas-lab .
* Working on Sun maintenance contract for LDAS equipment.
Livingston
----------
(Igor Yakushin)
* memtest on the new linux servers showed no errors.
* Sent three tapes to CIT.
* Received two T3s from CIT.
* Upgraded LSCDataServer to version 3.
Hanford
-------
(Greg Mendell)
* LDASsuccessfully archived and reduced all available E11 data. A detector elog
reports on the location of data at LHO. A copy of the RDS data has been
transferred to CIT; a copy of the raw data has been or soon will be transferred
to CIT. A report on gaps in the E11 data is posted here:
http://ldas.ligo-wa.caltech.edu/ldas_outgoing/archiver/
endE11GapCheck112404.txt.
All gaps appear to be due to DAQ reboots when both fb0 and fb1 were down
on the first day of the run. Note that the fb1 framebuilder produced 32 s
frames and the fb0 framebuilder produced 16 s frames. The raw data is a mixture
of these frames. The Level 1 RDS data is a mixture of 64 s, 32 s, and 16 s
frames, and the Level 3 RDS data is a mixture of 256 s, 64 s, 32 s, and 16 s
frames. (New options to LDAS createRDS jobs were successfully used to produce
frames of these sizes; the smaller size frames occur to fill in the gaps near a
true gap in the raw data as much as possible.) Gaps in the RDS data are
increased by +/- 16-32 s either side of those in the raw data because extra
data is needed for downsampling. Gap 5 in the RDS data is combination of gaps 5
and 6 in the raw data because the orphaned frame H-R-784762432-32.gwf in the
middle of raw data gaps 5 and 6 cannot be reduced because no extra data exists
either side for downsampling.
(Ben Johnson)
* Final L1 and L3 RDS files for E11 published last Wednesday.
* fb0's 3510 disk array has finally been connected to our FC switch in a proper
manner. The filesystem is mounted as fb0_frames on fb1, gateway, and
dataserver.
* All D2D scripts atLHO have been updated to FrCheck + md5sum source files. I'm
presently getting LLO into the same state (making sure config files are ok,
etc.).
* L700 tape robot hand is having problems. StorageTek will replace the
"gripper" on Dec 3 2004.
* Created a small util to read out the interferometers from frame files. It is
meant to be part of the LDR publishing process.
General Computing (Wallace)
MIT:
(Keith)
-Prep work for PAC meeting
-Brought up new test wireless router with SSH authentication in NW22
Livingston:
(Shannon)
-Set up an IDS box running snort. This is a test installation using snort
and SGUIL. SGUIL looks promising
(http://sguil.sourceforge.net/index.php).
This is basically just an
interface to analyze the snort alerts. I have a crude test installation
that is working. I will later firm up the configuration and install a
final version. I would also like to set up an additional layer that looks
at packets before we hit the firewall to compare what is being stopped by the
firewall to what makes it through. -Working on eliminating some of the unused
sun workstations. I will probably later put these to other uses. It
seems that most people are not using them much anymore, so the elimination of
these will make it easier for me to maintain patches, etc. since there will be
fewer Suns.
-Replacing the DNSserver this afternoon. This will eliminate one of the
two machines that are still running Solaris 8. The other is the web
server, which is a complicated upgrade.
-Still setting up machines to log to the central logserver. I have also
installed a script that emails a summary of the syslog events on each
machine. I am hoping that I will be able to keep between 6-12 months worth
of logs on record.
-Fixed a problem with the mail server that was causing the hostname to come up
as abundance.caltech.edu in certain circumstances.
-Talking with LSU about the problem of our router maxing out the CPU at 16
mbit. This is definitely an issue and we will have to deal with it
soon. Unfortunately, the hardware that is capable of doing what we need
to do is beyond our budget, so I may have to put in a custom solution.
-Received a quote for CanItPRO. This will likely replace RAV here for the
email antivirus and antispam. This is what CIT is using.
-Installed an SSH patch on all of the Suns.
-Received a UPS that was damaged by the shipping company. The vendor is
working with them on a replacement. Unfortunately, this means that it
will be a while before I can have the 3rd server rack ready.

198.129.208.1_198.129.78.122.html
- Working on maintenance contract renewals for several different items.
- Continuing the investigation of alternative network providers. Nothing much
new, except the phone company looks like a good possibility.
- The security hardening of the web/mail server caused the elog mirror updates
and the workpermits announcement emails to stop working. I'm working on
alternative methods for handling these functions. The elog mirror is
temporarily working, but not with the final solution.
- I've had to move homedirectories to new disks because one of the disks was
full.
- Created a couple new user accounts and removed several old ones.
- Misc. other user support.
CIT:
(Mike)
-Worked on spam filters, while Larry and Lisa were out on vacation.
-NTSRV's: (M79) Installed another SATA controller card, with two additional
SATA 400 GB hard disks. I also transferred all data over to new SATA drives.
-I Ran monthly ghost backups on all NTSRV's.
-I scanned the servers to see where we are at on patches. I have to go threw
and figure out what patches are the critical ones and hope they don't affect
the services, these servers are putting out. All and all we are not looking to
bad on the NT servers.
-40 Meter: I worked on a lab PC thathad some hardware issues. I ended up
building another PC that had ISA slots, in order to run ISA data acquisition
cards.
-Stan Whitcomb: Loading GC software on a new notebook for him.
-Loaded a laptop for the loaner pool. I have turned this into Ed Chargois.
-Additional onsite/phone user support, that included printing, software, and
networking issues.
(Veronica)
- Updates to the PAC meeting website. Moved PAC presentations and review
documents under password protection. Made updates to the roster database
and webpages, templates atthe internal b/board and other LIGO webpages.
- Prepared a set of high-resolution LIGO images for print for a publisher,
another high-resprintable image for a poster for Michael Smith.
- Loaded a loaner laptop for GC.
- Set up and monitored a webcast of the last LIGO seminar.
- Helped Sydney Meshkov with making a webpage for his SydFest images and
provided other usersupport.
- Updates to the LSC website.
(Lisa)
-Started monthly backups.
-Monitoring mail services.

contract. Ordered equipment for different people and delivered a number of
items that have been received.
-Setup a couple of hardware items including a new printer for the DCC.
-Resolved a number of issues for different users. Included moving files,
converting files, resetting passwords, cleaning up accounts and resetting user
configurations. Also, spent a little time tracking down a NIS+ problem on one
of the gateway machines, nothing major it just was not updating the cred table
properly.
-Assisted Lisa witha few e-mail issues. Still going through the spam filter
tables. It should be noted that since the upgrade, a larger percentage of spam
mail is being trapped.
-Regular work with documentation and meetings.

We have presented a proposed contract update to ASI, reflecting the reduced
scope and our calculations of the new cost and fee. ASI has made input on the
revised text, and is considering the cost and fee revision amounts. ASI is also
modifying a recent ASI listing of Contract Deliverables to reflect our comments
on the makeup of the Design Documentation Package; this will be incorporated in
the contract update.
The design effort at ASI is still on hold, awaiting the availability of Richard
Fleischner.
Actuators:
Nothing new.
Displacement Sensors:
We have received the 14 displacement sensors ordered from ADE for the BSC
prototype unit; the shipment item count and physical condition is acceptable.
Accu-Glass is delaying the fabrication and testing of the 3 feedthrough flanges
for the BSC chamber at LASTI, with 16 feedthrough fittings each, due to the
slipped LIGO schedule and their increased work load.
Seismometers:
Nothing new.
Galling/Dusting Test:
Nothing new.

Advanced LIGO Suspensions
Justin Greenhalgh from RAL and Caroline Cantley from the
Yesterday afternoon, Carol, Thomas, Caroline,
On Tuesday, we had a meeting on the suspension installation fixture design with
Ken Mason, Ken Mailand and Oddvar Spjeld. We will continue this discussion next
week. Yesterday we had a meeting on the suspensions documents that need to be
updated and reviewed, including the SUS DRD and the universal DRD. We will have
a review on these documents next year.
Tomorrow, we will have an interface meeting with Dennis and others about
outstanding questions the SUS group has.

1) Structures
We met to discuss progress of the overall structure work this week with
Dennis, Caroline and Justin.
The upper Structure is close to meeting our goal of a 1st resonance of ~ 200
Hz. Its manufacture has been discussed at length with Mike Gerfen.
The lower structure is progressing well but needs more support. Caroline and I
plan to provide this and have arranged a hands on meeting in
http://www.ligo.caltech.edu/~ctorrie/ETM/22NOV2004/picture0004.jpg

3) Visits
Caroline Cantley and Justin Greenhalgh are visiting this week from the
UK
4) Quad
During Mike Lloyd's visit we worked on assembling the top mass and
taking the upper intermediate mass forward from concept to detailed design.

Ian Wilmut, Mike, Janeen and I worked on moving forward the items RAL are
providing for the controls effort. A lot of these were previously at the
concept stage. I am confident that almost all of these are now either at the
level of detailed design or drawings that are almost ready for manufacture. We
also spent a lot of time in the lab working on various bench experiments, full
report to follow.

Both campus workshops continue to deliver parts associated with the quad.
We have prepared a mock arrangement in the lab to go through the assembly
associated with the "3&1" assembly

The AOS cost book has been scrubbed. A revised schedule for AOS was
detailed. The cost and schedule changes were sent to Carol W. and Thomas F. for
review.

I finished writing my annual status report to the Doctoral School Board where I
summarized the work I have done during this year.
I started new calculation of the thermal noise in finite size mirrors for mesa
beam changing the diffraction losses constraint to 5 ppm.
The next 4 weeks I will be in
Marco (30 Nov)
Mesa-beam cavity experiment:
I set a new output optics layout: now there is a new beam splitter and
photodiode disposition, a divergent Plano-concave lens has been added between
the beam splitter and the CCD camera.
Now we have more power in the photodiode and more space to place light filters
before the camera.
I draw a first schematic for the new PTZs driver circuit.
The next week we will try to operate with both current feedback and PZTs
angular corrections. In order to that I tested the old PZTs driver circuit
correct working.
Creep experiment:
We completed the data collection at the temperature of 900C . Now it has been
switched to 400C again. Im taking new data from November 26th.
