Summary of Commissioning
Activities at LIGO Hanford Observatory (Landry)
Mt. St. Helens remained active early in the week, disrupting
locking, as did construction on the Hanford site. Yesterday, seismic noise from
the mountain dropped off sharply, but magma is expected to be just below the
surface and eruptions remain a possibility, according to the USGS. Periodic explosions
do result in reduced noise.
Some commissioning highlights this week:
4K IFO
-----------
2K IFO
------------
LLO (Zucker et al)
---------------------------------------------------------------------
Some temporary patches remain due to parts shortages, but the full electronics
system is back up and running. Enough HEPI systems are in service to make a
substantial reduction in the net RMS motion of the interferometer arms. As a
result we have started aligning and trying to lock the interferometer again.
Rana Adhikari and Vuk Mandic are out from Caltech this week to help push.
In other news, Valera and Andri have been upgrading the main AS port
photodiodes to the latest revision. Rus, Ken and Mike have improved the
power distribution to the WFS, LSC and SUS systems, so all but one WFS board
(with an unrelated problem) are now functional.
Livingston Outreach (Thacker)
---------------------------------------------------------------------
Eskew+Dumez+Ripple contacted concerning incorporating heliostat into building
design
Museum/Center books ordered from ASTC
Preparing for Regional GEAR UP conference 01NOV in Biloxi, MS
Designing visitor program(s) for this year: demos; lessons, etc
Safety & security (Zucker for Riesen, Evans)
---------------------------------------------------------------------
Rich is away on vacation. Tom Evans responded to four system alarms; after
investigation all were resolved as either hardware issues, repaired, or system
"forces" (tests) during training of new personnel.
Computing (Roddy)
--------------------------------------------------------------------
Spent the last few days completely rewiring the network in the
auditorium. There is now a fiber uplink and a dedicated switch in the
auditorium. Still a few things to do in there (including cleaning up the
hundreds of feet of CAT5 removed) but all of the network ports should now work.
Spent the afternoon today at LSU discussing their future networking plans with
Sean and Ric. I had hoped to also meet with Boyd but he was on
vacation. Met the person who does the traffic shaping for the LSU
network. He says he will prepare a list of what is throttled and how so I
can provide this to Albert. They also say that they may up the speeds on
the I2 connection since Quest is offering it at a discounted rate, but this may
or may not happen.
HEPI (Zucker for Giaime, Shyang, O'Reilly, Mandic, Franzen)
---------------------------------------------------------------------
Valve failures have tapered off after some replacements on the BS, HAM1 and
HAM2 chambers late last week. However we had a failure of a position sensor at
Ex; a replacement was on hand at MIT and the system is back up.
Joe Hanson has done forensics on the decaying air pressure accumulators, and it
seems evident that these were simply defective and should not have left the
factory. The manufacturer has been contacted about their QA. We are
replacing the leakiest ones and monitoring the others to insure they remain
within tolerance. (NOTE: they leak air, not fluid. HEPI has had no fluid
leaks).
We have found HAM4 tripping its watchdogs occasionally for unknown reasons. It
seems to recover OK each time. Current working theory is insufficient gain
margin; this is under investigation.
SysID continues on ITMy and the BS; ETMx, ETMy and ITMx are now performing well
and routinely isolating. Since Ey was the dominant contributor to
full-interferometer locking problems there is already a substantial benefit to
lockability even without the rest of the corner station HEPI fully
commissioned.
CDS Software (Parameswariah)
---------------------------------------------------------------------
StorEdge 3510 Controller and disk firmware upgraded. Sun rep was here to walk
me through the upgrade. The disks were unmounted during the duration of the
upgrade and mounted back. A utility check was run on the controller and the
logfile was sent to SUN. SUN will confirm if we need a controller replacement
and if yes, when we will get it.
Replacing the 2nd 110B on hepi2 seems to have fixed the channel hopping
problem. We have not had any reports of channel hopping since then.
Renamed L1:PSL-ISS_MONPD channel to L1:IOO-MC_PWR_IN. Changed the database
records and the medm screens to fix this. The EDCU is ok and does not need a
change. Rebooted PSL and l1iool1 processors. Returned the PSL to the state it
was before the reboot. Both Ref Cavity and PMC Locked. PSL Half wave plate
working after the change.
Tested NDS Proxy for its working both from LLO and from Caltech. Alex
assistedme to test the nds from Caltech.
Edited the makestartup script to read saverestore.ignore file and remove the
channels from the autoburt.req file. Advantage: This now helps to remove those
strings that used to put the end double quotes to the next line causing the
burt restore to break.
Looking in to disk to disk backup. I have a setup for daily backup of major
critical disks.
Data analysis (Yakushin)
---------------------------------------------------------------------
LDAS admin:
1) Copied GEO data to LLO to use in joint LIGO-GEO analysis.
2) When working with GEO data, discovered a bug in LSCdataFind that would in
most cases miss the first GEO frame for a given time interval. Submitted a bug
report which was promptly addressed by Scott.
3) Configured LLO's cluster for matlab use so that Laura could run r-statistics
on S3 burst MDC frames.
Data analysis:
1) Produced LIGO-GEO waveburst triggers on S3 playground.
2) Produced more MDC frames (whistles, cusps, and inspiral) on S3 playground
per Peter Shawhan request. Testing them with waveburst now.
3) Testing how much better would waveburst do for 1kHz signals if we had not
restricted from the beginning the processed band by 1024 Hz.
4) Writing documentation that describes how to run waveburst for the benefit of
reviewers and for Siong to be able to run waveburst on LIGO-GEO data.
5) Discussing with Siong and Sergey the possibility of LIGO-GEO online data
analysis using waveburst during S4.
6) Preparing for the burst f2f meeting that will take place at MIT this
weekend.
HPLF, L1 Commissioning, and AdL Modeling (Franzen)
---------------------------------------------------------------------
1) Have been taking HEPI ITMY and BS sys id data which will be used for control
design.
2) Have been studying thermal distortion effects in a 100 W 1064 nm beam
passing through a piece of Schott OG-515 glass. The data are to be used for the
evaluation of a AdLIGO Adaptive Mode Matching design. See some preliminary
results at
http://www.ligo-la.caltech.edu/~franzen/HPLF/adaptiveMM/main.html
3) Evgeny Kamenetskiy, Andrey Shaykin and Viktor Zelenogorsky have joined us at
LLO. They will stay for two months studying thermal effects in an AdLIGO
Faraday Isolator at high input powers using the HPLF and its 100 W laser. I
have showed them the lab and we are making an inventory of additional equipment
we will soon need.
4) Further tests of the Melody AdLIGO Mode Cleaner model. Had some Femlab
problems which have been solved.
CDS software (Khan)
---------------------------------------------------------------------
1) Implemented RMS Watchdog system for LOS Coli Driver RMS Mon outputs
2) Worked with Chethan on fixing the bug in the NDS Proxy server.
3) Working on Rana's request of automatically updating the watchdog threshold.

PeterKing
The state code controlling the AC current adjust actuator
was modified slightly. The DC response of the actuator was checked
out. The documentation from Lightwave Electronics suggested that the
response of the actuator was +/- 10V for +/- 0.1A. For the laser down in
the PSL Lab at least, this was not the case and the response was more like +/-
1V for +/- 0.9A. This was checked out because I did not know what to set
the software current limit to so as not to cause an over current condition on the
laser power supply fault. The current was measured using the internal current
monitor.
The as-built power supply was compared with the schematic
from Lightwave and a few differences were noted. I do not know if the
differences are wide spread or not.
The state code does appear to work however, although the
dynamic range is not quite what I expected given the amount of diode
current. Thus far only the proportional gain has been dabbled with.
Further tuning is required.
Ken Mailand, Phil Willems
Working on packaging the hardware, purchase, and
manufactured parts, for the site installation Chiller Assembly.

Laurent reports :
Triple report
Hardware :
Installation was complete 2 weeks ago, since everything works well. We opened the
door to make some minor changes and mainly to study the problem I'll talk about
below. We removed the 2 top big screws (part of mass1) that enable you to
attach the tablecloth to the pendulum, the difference of weight moved the
position of magnets and we had to move the 3 top OSEMs. we also locked and 2
days later unlock the pendulum for the reasons we will see below. We tried to
place the seismic screws so that no magnet can be threatened by an OSEM.
software and results.
I am re coding an almost completely new software for the system ID, this time
including the possibility to drive a stepped sine and a modal drive.
We spent few days to investigate a strange problem, the data we measured seemed
to be wrong with a bad slope in high frequencies and a phase gap a 90 degrees
with the model. After having tested almost everything we could (and for example
locking the pendulum). It happened that the weird problem was a very simple one
: the whitening board for the OSEMs jumper were on so that the board applied a
filter with 2 zeros at 3Hz and 2 poles at 30 Hz ( which gave the global aspect
of a 1/f slope), I just placed every jumper on off position and now data are
much more better with a good slope and good phase. We will also make some
improvement on shielding of our cables.
Other LASTI activities:
PSL Upgrades
The PSL wiring upgrade continues
LASTI Infrastructure
We are building infrastructure in the highbay to create the necessary space to
assembled the Advanced LIGO Seismic and Suspension systems. This includes the
installation of a platform to store the top of the BSC when it is removed so
that it does not take up valuable floor space. In this process it is clear that
we have a couple of surplus vacuum tanks that we will be removing.
Simulation and Modeling
(Bhawal)
Weekly Physics Meeting
---------------------------
Hiro described new features of the released e2e package 2.1.0. Sany Yoshida
from Southern Louisianna University discussed some problems and issues related
to their simulation effort for combining Input optics simulation with the
simulation of the core optics part.
FFTprop
------------------
(Biplab) a matlab package named "FFTprop" is delivered to Luca and
Keita at LHO. This package can (i) do FFT propagation of phasecamera image from
one point to another through lenses and distances while keeping the resolution
same, (ii) do back-calculation - so if the camera image at a certain point is
known, it can calculate how the image looks like at some other point on the
path it has already passed through. The package (with explanation and example)
can be downloaded from
http://www.ligo.caltech.edu/~bbhawal/DOWNLOAD/FFTprop.tar.gz
Advanced LIGO Lock Acquisition
--------------------------------------
(Matt) Worked with Optickle to lock a low-finesse dual-recycled IFO. While I
was able to achieve lock on all degrees of freedom, there is still much work to
be done to make a viable acquisition scheme for Adv LIGO.
Simulation of 40m interferometer
-------------------------------------
(Monica) Better matching between Twiddle and e2e equilibrium fields values
thanks to the implementation of Twiddle inputs. Equilibrium fields values for
40m/advLIGO configuration with Mach-Zehnder have been calculated for a
modulation index of 0.1.
New Modeler Release
----------------------------------------
(Hiro)
A new package of modeler 2.1.0 has been released.
The major changes are
(1) A few bug fixes (axis rotation setting, preparation of header record,
reflection matrix) were fixed. Fortunately, they did not affect
SimLIGO results.
(2) More FUNC_X supports, and more robust use of static variables when
using dynamic linking
(3) More conforming to C++ standard. This code can be compiled using
3.4.1.
(4) 64 bit CPU compliant.
Alfi
----------
(Bruce) Work on the Box Settings Declarations editor.
(Melody) Continuing modifications to display the FUNC_X variables in a
friendlier user interface. Currently working on the simple view which parses
the C++ code in the MemberDecl primitive setting. Performing code integration
with Bruce's changes.
Last week;
Weekly Physics meeting
-------------------------------
Matt gave a status of LLO interferometer and its locking issues. Virginio
discussed about his work on injection and ramping-up of seismic noise into
SimLIGO to study lock-loss effects. Biplab described some FFT code results in
which small longitudinal displacements are generating large signals in WaveFront
sensors. Sany Yoshida discussed about a mode-matching problem they are having
with their e2e model of the Input optics system.
Commissioning
------------------------------
(Hiro) Discussed about the beam profiles and thermal lensing effects with Keita,
Bill and Mike Smith, based on the simulation results using FFT (G040328) and
analytic calculations (T040177, G040442). "FFT for Dummies" and a FFT
starter kit are being prepared so that Keita and others can run themselves.
Advanced LIGO lock acquisition schemes
-------------------------------------------
(Matt) Worked on Advanced LIGO lock acquisition schemes. To facilitate this
work I have generalized the frequency domain model used by LinLIGO (freqIFO) to
have a Twiddle like structure (i.e., it is now extensible to any optical
configuration). While this new model ("Optickle") is not yet
complete, it is able to compute DC power and demodulated signals in the
adiabatic approximation of static mirror positions. It is fast, operates directly
in Matlab, and should be sufficient to test low-finesse (i.e., auxiliary beam)
locking schemes.
Simulation of 40meter interferometer
----------------------------------------
(Monica) Still working on the validation of the equilibrium fields. Some
mismatching came out for the sidebands in the recycling cavities, they seem not
to be resonant: under investigation.
FFT Study: Length and Alignment correction
----------------------------------------------
(Biplab) Large Wavefront signals have been observed even for small (~1e-12
meter) longitudinal displacements when mirror phasemaps are included in runs.
Probably this is what is not allowing simultaneous correction of lengths and
angles (although separately both types of corrections worked). Study of its
cause is ongoing.
Outreach
----------------
(Biplab) Assisted Sany and his students Raghu and Tiffany from Southern
Louisianna University for their e2e modeling work.
Code maintenance
---------------------
(Hiro) Modeler code debugging: Several days were spent on debugging modeler
code to make it run on homam, 64bit AMD machine. The culprit was a code which
looks like double = - unsigned int * double; This worked OK on 32
bit gcc on Intel, but did not work on 64 bit AMD gcc. Fixed to safer coding.
Another fix was to make it compatible with gcc 3.4.1, which demands more
conformance to C++ standard.
Alfi
--------
(Bruce) Finishing initial version of Box Setting and opaque box features.
(Melody) Continuing modifications to display the FUNC_X variables in a
friendlier user interface. Currently working on the simple view
which parses the C++ code in the MemberDecl primitive setting. Checked in most
of the code changes.
Data Analysis Activities (Lazzarini)
Mendell:
Work continues on investigations for comparison of StackSlide with Hough and
Power Flux, using S2 and fake data. Preliminary S3 results will also be
generated before the November LSC meeting.
Shawhan:
* Made an additional set of "toy" simulated burst waveforms to
evaluate burst search algorithms:
http://www.lsc-group.phys.uwm.edu/cgi-bin/bag-enote.pl?
nb=burs3sim&page=3
* Helped Rana set up conlog at the 40-meter.
* Updated a number of LIGOtools packages, now with full support for Macintosh
OS X.
* Planning the Burst Group face-to-face meeting at MIT this weekend.
Yakushin:
1) Produced LIGO-GEO waveburst triggers on S3 playground.
2) Produced more MDC frames (whistles, cusps, and inspiral) on S3
playground per Peter Shawhan request. Testing them with waveburst now.
3) Testing how much better would waveburst do for 1kHz signals if we had
not restricted from the beginning the processed band by 1024 Hz.
4) Writing documentation that describes how to run waveburst for the benefit of
reviewers and for Siong to be able to run waveburst on LIGO-GEO data.
5) Discussing with Siong and Sergey the possibility of LIGO-GEO online
data analysis using waveburst during S4.
6) Preparing for the burst f2f meeting that will take place at MIT this
weekend.
Last week:
Mendell:
Reported on comparisons between StackSlide, Hough and PowerFlux searches at the
Sept. 28, 2004 CW telecon. One bug was discovered in the StackSlide code
which was fixed. The most interesting comparison is probably shown on
these S2 investigation pages (protected with the usual CW group password)
http://www.lsc-group.phys.uwm.edu/cgi-bin/enote.pl?
nb=puls2stackslide&action=view&page=17
and
http://www.lsc-group.phys.uwm.edu/cgi-bin/enote.pl?
nb=puls2hough&action=view&page=46.
The Hough and StackSlide code agree very well qualitatively, though the exact
algorithm that find the frequency at time t are very different in the two code,
which can account for the quantitative differences. However, we continue to
work along these lines to further debug the codes.
Shawhan:
* Wrote Matlab code to produce additional simulated waveforms for burst search
efficiency studies
* Read the GW-GRB correlation analysis preprint posted by the Rome Group
(astro-ph/0408544) and sent Peter Saulson a number of comments to forward to
the authors.
* Final reviewing of the S2 known-pulsar paper, which has now been approved for
release as a preprint.
* Worked a little on the S2 untriggered burst search paper.
Sutton:
This week I finished the new DMT "easy calibration" tool and placed
it in CVS. I have been editing the draft LIGO-TAMA bursts paper. I
have been helping prepare the white paper for the joint AURIGA-LIGO analysis,
producing pretty plots of the amplitude response of the detectors, drafting a
simulations proposal, and also producing sample MDC frames (with help from Igor
Yakushin). The MDC frames also include signals for GEO and TAMA, so they
could be used for joint analyses with those detectors as well. Finally, I
have examined the SNR at which various simulated signals became detectable in
the S2 bursts search. The SNR looks like a good predictor of detectability: all
of our 50% efficiencies occurred for SNR in the range ~10-20.
Yakushin:
1) Tested that calibration code is working correctly in waveburst.
2) Tuning waveburst on S3 playground in maximize efficiency and minimize
background rate. It turned out that if we want to be able to detect 100% of
strong enough WNB1, WNB2, SG5 signals (long duration bursts), we have to
increase the coincidence time window to 100ms in the postproduction analysis.
That leads to about 30-40% increase in the background rate.
3) Working on waveburst version 5 documentation.
4) Tested that current input mechanism in waveburst can read GEO
frames. Preparing waveburst to apply to GEO data.
5) Produced better time, frequency and hrss reconstruction pictures for
S2 paper.
6) Helped Patrick Sutton to fix bug in his modification of my MDC
script.
LIGO Data Analysis System
Software Systems (Blackburn)
New code for the createRDS functionality requested by the LSC Computer
Committee made it into the nightly build for last weekends testing of LDAS. The
new code cased roughly half a dozen of the integration and system tests to
fail. All of these have now been fixed. This means the code's backwards
compatibility is now in place, but new tests are now needed to test out and
exercise the new functionality for createRDS.
New versions of Xerces (C++ XML parsing IO library) and LAM (Message Passing
Interface Library) were tested on tandem systems this week. The Xerces upgrade
revealed no issues and was specifically to address an issue with new compiler
technology from GNU. The LAM upgrade was to fix an issue with hardware failures
that left dead files on a rebooted system and prevented LAM to start up. The
LAM development team provided a fix to this bug but we are having trouble
running LDAS with this new LAM on the test tandem environment. We will need to
investigate further before promoting the LAM upgrade. Also was able to upgrade
to the latest version of iODBC (open source Open DataBase Connectivity standard
library).
We have seen an increase in hard failures of nodes on the LDAS-CIT system which
has prompted several requests from system administration to enhance testing
capabilities of nodes and user accounts on the large clusters. These are being
integrated into LDAS along with built in tests under the controlMonitorAPI's
GUI.
An issue with single timestamp time ranging parameterization for the new
createRDS command was discovered in the TCL layers and fixed.
The code changes to support PR 2705 are now in and being evaluated. This will
allow tarballs of files to be pulled into LDAS for analysis in user commands.
Began the migration effort to port LDAS to Fedora core 3. Plans are in the
works to configure a tandem system with Fedora core 3 pre- release 2 and
rebuild all of LDCG and LDAS on that platform. This will probably require
several days of testing to identify any porting issues which may need code
changes, followed by more testing before we are able to migrate onto a bigger
system like LDAS-DEV and LDAS- TEST for more thorough "threaded"
testing.
Have wrapped up seven more XIO functions from Globus for use in TCL. There are
still a few more functions in the XIO subpackage to be wrapped. Presently
developing TCL test code to exercise these newly wrapped functions in a client
server simulation. The test programs are being debugged.
Researching the interactions between MyProxy and Globus client proxy along with
the GRAM for use in testing of the TclGlobus software in an automated
environment. A flow chart showing the interactions is almost finished.
Attended a griphyn/ivdgl management meeting on Tuesday morning in which the
discussion focused almost entirely on Open Science Grid issues. In particular,
the state of the current OSG "Blueprint" document and plans for upcoming
meetings. KB made arrangement to attend the next OSG Blueprint meeting at
Fermilab in about two weeks.
Last week:
IBM made the general announcement of its DB2 8.2 release to the community this
past week. A check of the Academic website shows that this has not yet made out
to our channels for downloading. However, it did reveal that two new patches
are available for the version of DB2 (8.1) that we are currently running. These
are now downloaded but I will wait to see if we can get the new release in time
for the Nov 15th LDAS release before committing to either the patches or the
new release in a week or two.
In an effort to automate nightly testing of the Tcl/Globus code being
developed, an issue with certificate authentication was identified. This was a
natural place to review the recommendation from out project advisory committee
to look into using myProxy. We held a meeting to discuss this possibility and
will install the myProxy on our Tcl/Globus project server over the next week
and explore the flow of a automated test script to perform the growing series
of unit tests we are developing to test the new Tcl/Globus wrappers.
Wrapped up the two XIO functions (globus_xio_read() and globus_xio_write())
this week and developed unit tests to validate these. A couple of refinements
have been identified for these wrappers and thier associated tests. These
functions handle all globus streams (file, socket, etc.).
The cmonClient now has new GUI controlled tests that allow the testing of all
MPI users and nodes on an LDAS system in response to the PR 1780 change
request. Also added support for selecting time ranges based on a LIGO run
(e.g., E10, S1, S2, etc.). Fixed the time selection widget to use "last 5
minutes" per request in PR 2682.
Fixed up PR 2706 - remove references to resource variable ::bwulfHost in the
controlMonitorAPI's server.
Close out PR 2355, wake up of dataRecv and non-dataRecv threads in the
lightWeightAPI.
Added an FAQ to the webpage for the 1.2.0 release of LDAS documenting a bug in
the lamboot code used by the mpiAPI. The LAM developers have provided a patch
and will be fixing this bug in the next LAM release.
Continued working on changes to the frameAPI and the frameCPP to support
concatenation and appending of frames in a frame file for the next release of
LDAS.
Began testing a fix to PR 2705 involving user commnands that fetch hundreds of
files for inclusion in an LDAS datapipeline as input data. This is being
implemented to use a tarball option.
Ran all LDAS system and integration tests on the development system using CVS
version 1.2.18. Updated webpages and cvs with results. No surprises. Had to fix
a bug in the dcmangle diskcache test script to properly use the new /scratch
file system mounted from SAM/QFS.
Continued review of Open Science Grid documentation on the web while also
continuing to dig through the latest version of the "blueprint"
document.

(Dan Kozak)
* All LIGO data in HPSS has been copied to SAM-QFS and deleted from HPSS.
*I'm now working on getting other people's data off of LIGO tapes (that was put
there by mistake) in HPSS so that we can reclaim the tapes for SAM use.
* Still working on getting STK maintenance quote.
* Tracking down missing labels for cleaning tapes.
(Al Wilson)
* Repair of node113, needs a new motherboard. System is out of warranty. Will
have to be ordered. Replace with node7 from the TEST system. Data recovered.
* ldasbox2 repair. Found the bios to be bad reflashed. Hard drive is now having errors. Will replace when
data is backed up.
* Helped GC with a setup of a laptop for redhat.
* Installation, and distribution of BB monitor of the nodes.
(Stuart Anderson)
* Tested SAM-QFS version 4.2 in combination with SAN-4.4.2 and the latest
Solaris 9 Recommended Patch Cluster. This version has passed initial testing
and is now running on the LDAS-DEV and TEST systems. Unless a new problem shows
up we will start upgrading the production systems to this version next week.
* Installed and started testing Fedora Core 3 Test 2 on my laptop computer.
LDAS version 1.2.30 builds successfully and all unit tests pass on this version
of Linux.

* Installed new certificates on gateway.
* Copied GEO data to LLO to use in joint LIGO-GEO analysis.
* When working with GEO data, discovered a bug in LSCdataFind that would in
most cases miss the first GEO frame for a given time interval. Submitted a bug
report which was promptly addressed by Scott.
* Configured LLO's cluster for matlab use so that Laura could run
r-statistics on S3 burst MDC frames.

* I have added the follow options to createrds.tcl and createrdsGUI.tcl, which
are set in the resource file createrds.rsc: 1) "set includedirs [ list ...
]" (If includedirs is not an empty list, reduce input data from these
directories only) and 2) "set excludedirs [ list ... ]" (if
excludedirs is not an empty list, do not reduce input data from any of these
directories). The default is that these are empty lists, and everthing works
just as before. These options can be used to reduce just the locked
stretches of archived data, rather than all the data produced by the
framebuilders. The changes have been checked into CVS:
CVS/Root =
:pserver:USERNAME@gravity.phys.uwm.edu:2402/usr/local/cvs/lscsoft,
CVS/Repository = dsorun/contrib/createrds/scripts.

* The cluster at LHO how has S2+S3 L3 RDS data for both observatories, and is
only lacking S3 L1 RDS data for Livingston. Spraying the LLO data and
publishing the entirety of the L1 RDS data still needs to be performed.
* Firmware/hardware upgrades for the 3510's at LHO completed. Save for
the 3510@fb0's disk firmwares.
* Daily segment archiving GUI has been finished. This should allow for easier
segment archiving by the operators at it automatically runs and parses the
conlog.
* Attempting to revive the control room web page display computer. It needs a
BIOS reset to get it to boot. It probably needs a new processor and or
motherboard. This is certainly a backburner issue, though.

Spent the last few days completely rewiring the network in the auditorium.
There is now a fiber uplink and a dedicated switch in the auditorium.
Still a few things to do in there (including cleaning up the hundreds of feet
of CAT5 removed) but all of the network ports should now work.
Spent the afternoon today at LSU discussing their future networking plans with
Sean and Ric. I had hoped to also meet with Boyd but he was on
vacation. Met the person who does the traffic shaping for the LSU
network. He says he will prepare a list of what is throttled and how so I
can provide this to Albert. They also say that they may up the speeds on
the I2 connection since Quest is offering it at a discounted rate, but this may
or may not happen.

-Still spending time on purchase related items. Had a special account setup
with one vendor because of the difficulty contacting the sales rep.. It took
some time to get the cables needed by the LDAS group. The manufacturer changed
the cable configuration but we eventually found someone that could supply the
cable type needed by the group. Received a number of orders from different
companies and still tracking down items that we should have received by now.
Started placing orders to replace some of the older desktop computers.
-Spent a deal of time tracking down files and file systems for different
people. Most were files from people that had left the project and were needed
by others referencing those files.
-Spent some time on cybersecurity issues. I will be spending more time on
related items over the next few weeks.
-Still trying to work things out to clean off old unused file systems.
-Spenta day repairing a number of functions that no longer worked properly
after installing a series of critical patches on one of the sandboxes. Some
applications needed to be re-installed, others turned off and/or removed. A few

SEI Structure:
A meeting was held with ASI on 10/1 to negotiate which unplanned activities
on their task were caused by LIGO's requested scope changes. Of the 8 liens
existing, 6 were accepted by Caltech, for a total added fee of 16K. The 2
remaining liens for a total added fee of 41K were not accepted, and may be
discussed again if ASI feels that they can better justify their case.
A meeting will be held with ASI on 10/8 to discuss the following:
1. A decision on whether ASI will be providing a fixed price proposal for
fabricating the BSC prototype parts; in addition, other tasks from the current
"cost plus" contract may be proposed as fixed price, as well. I had
erroneously reported 2 weeks ago that the 10/8 meeting would be covering the
presentation of the fixed price proposal. That will be done on 10/24, assuming
that ASI decides to go ahead with the proposal.
2. Updated fabrication cost estimate
3. Contract document markups from ASI, covering the latest changes
4. Status of shear slip analyses, design changes
5. Status of global tolerance policy document
6. Status/schedule of scheduled items remaining (especially drawing releases,
bid packages, assembly, shipping)
7. Status of weekly reporting plans
8. Status of Ken Smith's writeup on the tilt effects of side and end loads on a
curved blade (action item #38; Ken's e-mail of 8/2, expecting to wrap up his
writeup "that week")
9. LIGO's response to Tony's questions in 10/1 meeting: analysis manual,
correlatable analysis model, solids model file format, insert installation
10. (when ASI is ready to discuss) negotiation of remaining liens: TBD Tasks
#1, 2
Actuators:
Bob Taylor received and precleaned the 6 large bobbins and 6 small bobbins
and shipped them to PSI for winding.
Displacement Sensors:
ADE is proceeding with fabricating and testing the 14 displacement sensors
for the BSC prototype structure.
Accu-Glass is proceeding with fabricating and testing the 3 feedthrough flanges
for the BSC chamber at LASTI, with 16 feedthrough fittings each.
Seismometers:
We received 5 spare cables that were ordered for the STS-2 units.
Galling/Dusting Test:
Nothing new.
Other:
Ken Mailand and Larry Jones will be meeting with Astro Pak on 10/8 to begin
planning the task for cleaning, air baking, and FTIR qualifying of the BSC
prototype parts that are too large for LIGO personnel to process. These total
21 pieces of 12 different parts, with mass totalling over 3700 lb. The heaviest
part is the optical table, bottom half, which weighs 1020 lb. These parts are
difficult to handle and will require special fixtures and handling. A
pathfinder task is planned to help determine cleaning and FTIR process
specifics.
Needed specifications for the in-vacuum cables for SEI and SUS are being
discussed, in preparation for ordering the cables.

1. QUAD Update
All of the drawings for the Top mass are now in workshop. CES and the Physics
shop are progressing well with the various work packages.
The majority of the drawing packages that are being worked on have interface
related questions and are associated with either Calum or Mike Perreur Lloyd.
Our plan is to review the parts, check interface related questions, apply any
re-works and then start the release process. MPL is visiting Caltech later this
month when his parts arrive from the shop.
A further set of drawings including ideas for assembling the top mass, wire
clamps for assembly, blade clamps and the penultimate reaction mass should be
ready for review by the end of the week.
2. FEA of Structure and 2 concepts for the design approach
The FEA work continues. To incorporate the two assembly approaches we are
trying to obtain a first resonance of ~ 200 Hz for the upper half of the
structure, ~ 80 - 100 Hz for the lower half and ~ 100 Hz for the combined
structure.
3. Blades
We are expecting the test blades from VP any day now.
CES report no problems.

5. Visit by Tim Hayler
Tim Hayler is visiting from RAL. The SUS team put together a list of items
related to the noise prototype effort. In order to aid in bringing Tim up to
speed he has been aiding with the structure analysis, learning about the
"3&1" assembly and how to implement it, understanding the GEO
catcher work and spending time in the lab with the various suspensions and hardware.
