The LIGO Executive Committee Agenda for Monday October 18, 2004 will be:
(Meeting time: 10:30 am Pacific Time)
Special Items:
no report
STATUS OF LSC MOUs (Petrac)
(No report--vacation)
SITE TELECONFERENCE (Jasnow)
A site teleconference was held on Thursday, October 14,
2004. The following issues were among those discussed:
The issue of cost transfers was
discussed. Transfers for expenditures over 90 days old require the
signature of the Division Chair and the Controller, so it is important to keep
track of expenditures as they occur to be sure they are being allocated to the
correct account and are the correct expenditure type.
A follow-up audit has been
scheduled at LHO by the Caltech Office of Audit services and Institute Compliance.
This audit is to assure that the recommendations of the previous audit are
being followed. The audit will take place the week of October 25.
A bulletin issued by the
International Scholars Services Office has clarified the issue on the H-1b visa
cap, stating that it does not apply to institutions of higher education, or a
nonprofit research organization. Therefore, LIGO can continue to hire
foreign staff with H-1b visas. The bulletin also urged foreign staff
traveling abroad who need visas to re-enter the U.S. visit their office before
traveling to assure that they have correct documentation to secure such a visa.

Outreach (D. Ingram)
------------
On Sept. 30 Fred Raab and Dale Ingram attended a lunch meeting of the Tri-Cities
Industrial Development Council (TRIDEC). LHO is a TRIDEC member. We
will stay abreast of plans to expand higher ed opportunities in the Tri-City
area that were discussed at the luncheon . Jerry Schneider, a program
manager for economic diversification with Fluor Hanford (the main Hanford
contractor) visited LHO on 10/5 and discussed with Fred and Dale ways that
LIGO's presence might contribute to local economic and intellectual
development. Benton City High School junior Preston DeLong visited on
10/8 for a one-day job shadow, an activity that we would expect to increase at
the site since many schools require job shadows as part of career ed. LHO
is planning to offer a public unveiling of Einstein@Home as a way to kick off
the World Year of Physics. We will wait until the delivery date for
the software is firmed up before we begin publicizing the event. We will
hold a meeting of our Local Educator Network (LEN - our advisory council on outreach
issues) on 11/4.
Excellent progress this week on restoring the interferometer to operation.
Rick Savage came down from LHO to help install the new frequency servo (TTFSS)
and it works beautifully. He also helped us finally (we hope) resolve a
long-standing cooling issue on our NPRO, so we are hopeful it will be much more
robust. Rolf came down to install the latest code versions and some faster
processors to give us more headroom on ISC as well as HEPI realtime controls.
This new code also allowed us to finally tie the long-term tidal signals into
HEPI; one-arm tests showed this is a huge improvement. Rana and Vuk
continued to work with the local crew on locking the interferometer and are
making rapid progress. We hope to start looking at noise spectra this week.
Livingston Outreach (Thacker)
---------------------------------------------------------------------

LASER SAFETY
1). Addressing LSS access control logic which is non-consistent between the
5 laser tables.
2). Updating Laser Operator and Authorized machine shop user signage.
SITE SAFETY
Found no safety concerns during the weekly site tour.
PROPERTY CONTROL
Working with Ed Chargois and Tom Evans in the disposal process of computers and
monitors that are no longer in service.
Thermal Compensation (Frolov)
----------------------------------------------------------------------
- new X arm chiller from Neslab was hooked up and turned on this week
- new power connectors with fused switches were installed on both TSC lasers.
The lockout boxes were ordered for this connectors.
- additional PSL toroidal transformer installed. Both TSC tables were powered
on to test the power supply and X arm chiller. No problems are seen so far. TSC
is off until TSC commissioning restarts.
- TSC interface electronics is expected to arrive within two weeks.
AdL and LIGO 1 Mechanical Engineering (Spjeld)
---------------------------------------------------------------------
- finished the updated UHV Oven drawings (no change, just additional views)
- sent RFI and ROM to possible vacuum chamber and oven manufacturers
- received photon calibrator support shelves from machine shop
- finishing LLO layout 3D-models for museum LIGO exhibition
CDS Software (Parameswariah)
---------------------------------------------------------------------
Installed Hanford crude Ramp down code. The code runs as a cron job on LLO1 as
ops every minute and decrements the max variables by 10 every minute if it
exceeds the limits.
Requested DAQ Changes completed and tested. Rana's elog entry requested the DAQ
following changes.
Test points that were not in the DTT channel list but added now:
----------------------------------------------------------------
L1:LSC-NSPOB_IN1, L1:LSC-NSPOB_IN2, L1:LSC-NSPOB_OUT
Channel Names change:
-------------------------
L1:LSC-SPOB_MON -> L1:LSC-SPOB_I
L1:LSC-SPOB_OMON -> L1:LSC-SPOB_Q
ISS Channels added:
---------------------------
All of the new ISS channels which are for the inner loop. These should all be
16 kHz and as such, shouldn't have 850 Hz LPFs. These are not checked for
filters yet. Will be looked into this afternoon.
Also I have added both Whitend(_W) and Non-Whitend(_NW) channels for
L1:PSL-ISS_CURRSHDAQ, L1:PSL-ISS_OLSENSPD, L1:PSL-ISS_OLMONPD
L1:PSL-ISS_ILMONPD, L1:PSL-ISS_ILSENSPD
If there is a decision made to keep only part of the above 10 channels, then we
must remove the rest to save frame builder disk space.
Checked all the ISS DAQ Channels are 16 KHz. Had to remove filters for 2
channels. Also tested the channels. Some channels are railed and needs to be
checked at the ISS box
FBO was down after the above channel addition due to disk space fill up. Fixed
the directories that were removed and reduced the full frames to 2 and
1/2 days.
Working with Rolf on CDS changes. New 2.2 GHz processors installed on the RM/BS
and ITM. A linux boot server installed in the MSR. Both RM/BS and ITM
processors are working now.
Moved the 1.6 GHz processors from RM/BS and ITM to HEPI corner station
processors. Installing the tidal input code for HEPI.
General Computing (Roddy)
---------------------------------------------------------------------
Installed various software packages this week. Visual Studio, Matlab,
etc. on the visitor's machines.
Working on a couple of quotes for some network monitoring servers.
Spent a lot of time yesterday trying to get a USB memory stick working with
Solaris in an acceptable manner so that I can keep my public/private keypair on
it for encrypted email. Part of the security push is for the admins to be
able to send encrypted emails back and forth. This is turning out to be
fairly difficult to do on a one user basis when the user uses different
machines & platforms on a daily basis (like myself).
Finishing up the auditorium. I need to get with John and show him what
has been done in there in the last two weeks.
Data analysis (Yakushin)
---------------------------------------------------------------------
LDAS and Condor administration:
1) Upgraded LSCdataFind server and client to fix the bug observed with GEO
frames.
2) Upgraded Condor to version 6.6.6.
3) Changed passwords on LDAS and Condor machines.
4) u1d2@t3-6 failed and was replaced by u1d8@t3-13.
Data analysis:
1) Attended burst face to face meeting at MIT. Gave presentation about
waveburst efficiency on MDC frames:
http://www.ligo-la.caltech.edu/~igor/MDC_S3_P/
Final_waveburst_configuration_for_S3.html
2) Helping Siong and Michele to get started with running waveburst under
Condor.
HPLF, L1 Commissioning, and AdL Modeling (Franzen)
---------------------------------------------------------------------
1) Have been training Evgeny Kamenetskiy, Andrey Shaykin and Viktor
Zelenogorsky to utilize the HPLF. They have now been certified as HPLF Laser
Operators by Safety Officer Rich Riesen and have already started to perform a
series of experiments including high power tests of an ADLIGO Faraday Isolator
prototype. We have performed an inventory and have ordered several additional
equipments needed for the experiments. Have also been solving several practical
issues related to their visit like hotel and transportation.
2) Have continued the ITMY and BS HEPI SYS-ID. The ITMY data are now done while
the BS needs to be improved a little around 0.5 Hz. I am also trying to learn
how to design the required BS and RM control filters in order to be able to
contribute to the efforts of the HEPI team.
CDS software (Khan)
---------------------------------------------------------------------
Implemented a Watchdog timer that reloads the original MAX_VAR value of the LOS
Coil output after an expiration of 2 minutes. The watchdog is there to protect
an accidental over limit value on the MAX_VAR input. This is purely a database
implementation which is easy to maintain.
Working with Rolf and Chethan on the CDS upgrade.
see also the CDS weekly meeting minutes in the commissioning archives:
no report
(Rolf is at LLO this week installing new code and supporting
HEPI controls commissioning.)
Held a review of the Fiber Optic Timing Link system. Review
committee report is pending.
Ben Abbott reporting
RFPD Redesign:
1) After much review, the gerber file went to PCB Express
this morning for two prototype boards.
2) The long lead parts are either here, or on their way, and
the Digikey order will be placed tomorrow.
ISS:
1) Six ISS PDs have been shortened to be used on the PSL
table where the beam height is only 3".
2) These modified blocks will now be stuffed with their
electronics, tested, and shipped by the end of this week.

The latest revision of the intensity servo is being
fabricated. The first production model is expected to be tested later
this week. As part of the preparation for the installation of the servo
at LHO, a set of MEDM screens was generated.
At the last test drive of the low-frequency intensity servo
state code, I left feeling that the code worked and the problems encountered so
far were because of the current limit of the laser power supply. The maximum
total current was not increased after installation of the modified current
shunt leaving less current for the AC current adjust actuator.
Ken Mailand, Lee Cardenas
The chiller first article manufactured parts are in the CIT shop
and should be complete
Tue. 10-19, purchased parts are in house, and assembly should take 2 days.
Bill Kells, Liyuan Zhang
Have some good Reflection/Transmission Scanner (RTS) results now on directly
scanning HR surfaces to identify the "point" scatter loss. The
results are remarkably clear, however we are still interpreting. Now that we
have demonstrated a viable technique, I predict that a selection of samples
will need to be similarly measured to bring out full understanding . For
example something from Mackowski.
Mike Smith
I have written up the analysis I made of the astigmatism in
the power-recycling cavity, and will distribute it shortly as a technical note:
T040204-00, Astigmatic Spot Size in the Power-Recycling Cavity Caused by BS
Curvature.
The astigmatism introduced into the LIGO1 power-recycling
cavity by a non-flat BS affects the degeneracy of the cavity differently in the
vertical and horizontal directions for the transmitted and reflected arms. When
the ITM is relatively unheated, the astigmatism dominates the mode shape of the
cavity and causes the eigenmode spot size to become highly elliptical. This
effect may be the underlying cause of the elliptical side-band beams that are
observed at the antisymmetric ports of the LIGO interferometers.
The effect of the thermal lensing, which occurs due to
absorption by the ITM substrate, on the vertical and horizontal eigenmode spot
sizes of the power-recycling cavity is calculated, using actual values for the
radii of curvature of the LLO and LHO BS mirrors.
The calculated power needed to achieve stability of the
eigenmodes agrees semi-quantitatively with the recent observations using the
TCS and the phase camera.
The calculations agree with the observations that the ITM in
the reflected arm of the recycling cavity must be heated a greater amount than
the ITM in the transmitted arm in order to produce equal spot sizes of the
side-band beams in the two arms. The effect is significant in the 2K IFO with
the 83 km BS HR radius. The 163 km and 203 km BS radii cause a somewhat lesser
effect.
I am in the process of studying the quantitative
observations made by V. Sannibale of the LHO 2K Michelson AS astigmatism during
July 2002.

OTF Lab. (W. Bridge)
The chamber has two samples, white Ceramabond, and disks of TRA-BOND #2254
color light brown epoxy. Cavity is locked.
We continue taking measurements everyday. No Change
Absorption Test Measurement prototype in standby
Scatterometer system in progress
The Inner test mass 2ITM04 fused silica mirror is in the scatterometer
enclosure.
We have finished scanning the entire mirror surface for scattered light.
We can see many spots on the mirror surface more than it was measured in LHO by
Bill Kells
We think that probably the real scattering centers on the mirror, which it
could be on the
coating or on the substrate itself.
The latest results can be seen at: 2itm04_hrs4_1.pdf By: Dr. Liyuan Chang.
The Quantronix 60 watt laser No Change

(4) disks of TRA-BOND #2902 color silver epoxy. The cavity is
locked.
We continue taking daily measurements.
Cavity #2 in standby
We took the old chamber with its legs welded to have it cleaned and
bake.
We got the viewport windows and the base mount for the cavity, already baked!
We'll start to put the chamber together and mounting all the components.

- The lock acquistion code using the linux pc running epics is now operational
and can auto lock the mode cleaner, north arm cavity and south arm cavity.
Features to record lock times, durations and duty factor are being added.
(Mason, Ottaway, Sarin, Allen, Mittleman, MacInnes,Ruet)
Bob Laliberty, a mechanical technician from CSR will be starting monday
working with Myron 3 days a week. Bob will help dissassemble the prototype quad
and vacuum chamber, remove the old style seismic isolation from the BSC
chamber, and other work in preparation for the assemblly and installation of
the advanced Ligo seismic isolation and suspensions at LASTI.
Completed the design and structural analysis of a stand to hold the BSC dome at
LASTI. This is needed to clear floor space during the advanced ligo
seismic isolation and quad suspension installation. Floorspace in the high bay
is needed for 3 assembly areas, a seismic subassembly area, a seismic
overall assembly area, and a test stand for the seismic isolation and quad
assemblies prior to installation into the BSC chamber.
Data Analysis and
Computing (Lazzarini)
Simulation and Modeling (Bhawal)
FFT study
--------------
(Biplab) Tried to understand from FFT results for various cases for the
interferometer: Why, in the presence of mirror phasemaps, it was not possible
to do both length and angular corrections together, although separately those
could be achieved. Results indicate that choices of values for Beam-splitter
thickness and size/shape of its diaphragm have impact on the calculation of WFS
signals for yaw and could give incorrect yaw offset values.
Alfi
------------
(Bruce) Completing work on the Box Settings Declarations editor.
(Melody) Continued 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. Finished code integration
with Bruce's changes. Working on the consistency of the displayed default
values.
Data Analysis Activities (Lazzarini)
Mendell:
I've checked into the LAL inject package fixes for bugs in
LALFastGeneratePulsarSFTs (a fast way to produce SFTs for Monte Carlo
simulations): 1) the trig lookup tables (LUTs) code could run off the table,
and 2) a factor of two was missing in the use of the polarization angle.
I've also updated the tests of this function when "make check" is
run. (Files checked into lal/packages/inject: GeneratePulsarSignal.c
GeneratePulsarSignal.h and GeneratePulsarSignalTest.c) These bugs did NOT
have an effect on any of the current searches. Only the StackSlide search
currently used this function, and it avoided the bugs by turning off LUTs and
using random polarization angles during Monte Carlo simulutions (so the factor
of 2 did not matter).
Shawhan:
* The Burst Analysis Group had a very productive face-to-face meeting at MIT
over the weekend. Besides helping to organize and lead the meeting, I
spent some time looking into the effect of amplitude consistency cuts for the
S2 burst analysis. Erik and I also have been coordinating the slate of
talks for the November LSC Meeting and for GWDAW.
* Talked with Greg Mendell and others about mechanisms for
"discovering" science-mode data segments during online running.
* Wrote a little gui to help test the Einstein@home screensaver
software.
Yakushin:
1) Attended burst face to face meeting at MIT. Gave presentation about waveburst
efficiency on MDC frames:

2) Helping Siong and Michele to get started with running waveburst under
Condor.
LIGO Data Analysis System
Software Systems (Blackburn)
LDAS:
Created a tarball of the changes to the diskcacheAPI C++ source code that Mark
Turner left. This will support more general GPS time interval frames in
subdirectories. This tarball has been attached to the PR that is associated
with this code (2392) since it is untested and not ready for CVS. This is not
critical functionality for the next LDAS release so we will postpone working on
the code and testing it until critical requirements are in place.
Made code changes to the thread ID argument class constructor to test if the
argument is Null.
Have now successfully generated RDS frames files with LDAS that contain multiple
frames per file. These RDS files have been tested and verified for content, as
well as being used in LDAS jobs. A specialized test script was also developed
to be added to the LDAS system test procedure to verify this functionality on a
weekly bases. Currently expanding the test program to include generation of
concatenated RDS frame files where the time series data has been extended in
length within single frames.
Checked on availability of DB2 version 8.2 for academic licenses. Still not
posted on website for academics, but this is not unusual given how long
previous releases took to be posted there.
Began working on PR 2451 to correct issue with internal nodes in the cluster
using for master MPI processes being unintentionally reused for slave processes.
The new LDAS command to resolve PR 2705, too many files being retrieved
separately in a single job is now completed and utilizes tarballs of files.
Documentation on the new command structure is being written and when complete
the PR can be closed.
Modified all graphs in the controlMonitorAPI's GUI to use text widgets for
displaying info instead of label widgets, allowing more data to be inserted and
printed in a single graph. Also added support for printing any size of graph.
This is associated with PR 2682.
Added LSYNC test documentation. Working on adding an LSYNC integration test to
the weekly test procedure.
For the most part the system and integration tests results were much improved
this week after fixing the half dozen issues that were part of the recent
upgrade of the frameCPP and frameAPI code to support the new createRDS methods.
One mystery is that this resulted in a discovery of tests for frames that
should have failed prior to the code upgrade actually passing. The behavior is
now correct, but the earlier test scripts were incorrectly reporting a pass
that should have been a fail.
Activities on the LIGO/GriPhyN project are now in the last couple of weeks of
preparation for the Super Computing Conference. The focus will be on running inspiral
DAX scripts on mulitiple condor clusters. There probably will not be any
demonstration for the pulsar search given the intensity of things still needed
for the inspiral search demo.
TCL/GLOBUS:
Currently developing a TCL Test Client/Server Application that utilizes six of
the asynchronous XIO SWIG wrapped Globus functions.
Also worked on a TCL Test Application that utilizes two of the scatter
read/write XIO SWIG wrapped Globus functions
Documented how to acquire certificates for running Globus applications and how
grid-proxy-init works (the Globus GSI API uses this to generate the proxy
certificates. Began reviewing ways to document SWIG interfaces that are being
exposed to TCL as part of the project.
Installed the MyProxy client and server software on the tclglobus server box.
Still need to test out the client for this.
Held a meeting to go over the current usage of Tcl/Globus and the steps being
taken to run globus functions. This included evaluating all the parameters and
data products associated with the GSI process. Also reviewed how this
authentication applies to our Tcl/Globus test scripts.

CIT:
(Mike)
-Dennis Coyne: I finished up loading engineering software and transferring
Dennis's data to his new Dell workstation, and I swapped out his old computer
equipment.
-NTSRV: Pictorkeeps rebooting itself. This turned out to be a DS1410D service
that was trying to run, causing many system errors that would lead to a reboot.
This service is for a (Parallel Port Button Holder.) I am thinking this has
something to do with the FlexLM services that are running on this server. I
remove this service from the registry and rebooted. (Fixed)
-Wilson House: Wentdown this week, due to their fast-iron network switch going
out. Larry and I swapped this out, with a backup switch we had stored in GC.
-Continued loading software to setup a visitor's workstation in Bridge Annex.
-I tried loading LINUX on a new Dell computer that came with Broadcom NetXtreme
57xx Gigabit C onboard Network Card. After creating a network boot disk with
the Broadcom drivers I was able to get to the network, but I came across a
problem with partitioning scheme. LINUX OS would not recognize the Serial ATA
hard disk.
-NTSRV: I ran a security audit using the CIS software, and found many security
patches that were missing on all NTSRV's. I have updated all NTSRV's with
current patch levels and made other security changes. I still have more
security procedures to test before trying to implement these changes on all NT
servers.
-Other misc. onsite/phone support.
(Veronica)
- LSC website: Updates to the November Meeting webpages as they arrive. Updates
to papers under LSC review webpage.
- LIGO website: Installed the latest newsletter and troubleshoot the code.
Addressed the issue of updates to the LIGO seminars page; these postings will
now be made by Sharon. Larry and I have set up a template to help her started
and advised on how to use it. Updates to the webpages for the upcoming NSF
review and PAC meetings. Set up a password-protected directory for the NSF
review proposals. Misc. user support.
- CaJAGWR website: Updates to the upcoming seminars webpage.
(Larry)
-Replaced the edge switch for Wilson House. This installation took more time
than it should have. The programming of this edge switch is different than the
other edgeswitch units which caused some confusion in getting it up and
running. The company assures me that they are working on getting the setup of
the switch to be similar to their other switches. Once the unit was programmed
Mike and I were able to install the unit.
-Took the opportunity, while working on Wilson House and having Mike around to
help, of swapping out the UPS batteries and the single mode edge switch
connection to a multi-mode connection.
-Took a couple of days going over a number of logs and checking out different
file systems. This is to help in cleaning out old accounts as well checking out
a hack on one of the systems.
-Went through a number of procurement items. Still no feedback from SUN so I
will have to ping them again. Working on a getting a new updated maintenance
contract with Foundry. Ordered a number of workstations for the LDAS group but
their installation will have to wait until a new LINUX kernel is out. The
present kernel doesn't support some of the h/w and there are plans to update
the LINUX OS at the end of the month.
The 400GB disk drives ordered in May finally arrived. The company that the new
tape backup system was ordered from is now trying to clear up a problem on
their end. They made a partial shipment and someone closed the order so now
they are trying to open it up again and get the rest of the equipment shipped
out to us.
The IDEAS licensing is still in limbo. Campus is working on it but no new
information so far.
-Assisted Lisawith a couple of e-mail issues. Setup a couple more e-mail alias
groups. I will change one of the setups to where others can edit the group file
and not depend on someone in the admin group to do it for them.
-Having Lisa and Mike run a few audit scripts on the servers, SUNS and PC's.
These will take some time to review and have the units updated but the work is
going on and should wrap up (this round) in the next week or so.
-Assisted a number of users with different items. Setting up PC configurations,
getting their e-mail setups to minor printer repairs.
(Lisa)
- Spent most of my time doing a security audit and beginning the process of
updating all the servers in the server room. This is a big job that will
take a substantial portion of next week as well.
- Spent quite a bit of time teaching Sharon about web pages.
- Did monthly backups.
- Spent time cleaning up the home disks.
- Misc. user support.

Advanced LIGO Seismic Structure
SEI Structure:
A meeting was held with ASI on 10/12 with discussion as shown below:
ASI has now decided to include all of the remaining task of the current
cost-plus contract, in their proposal for a fixed price contract. They expect
to present the proposal on about October 22. ASI expects to present an estimate
of cost and schedule for completion under the current contract at the same
time. They gave a bounding of schedule slippage of "a few weeks to six
months", to which LIGO objected. They will attempt to minimize slippage,
and possibly offer an option for a tighter schedule. VanderZyl has stopped most
of the work on this task until better planning and cost control tools are in
place; at that time (near the end of Oct), the contracting mode will likely
have been determined. He is developing other proposals for cost savings,
including LIGO's direct purchase of some items (to save ASI's G&A charges)
and possible changes in ASI's methods.
ASI presented their Contract document markups, covering the latest changes;
this will be reviewed by LIGO and implemented.
ASI has completed their shear slip analyses and made the necessary design
changes.
ASI has completed the global tolerance policy document and has begun
implementing that policy.
ASI presented a "weekly" report as of 11 Oct (their first in four
weeks), and has committed to posting these on their LIGO web site weekly in the
future.
ASI has released several drawings in the last month, but did not post them on
their web site as they had previously agreed. They will return to that policy.
Ken Smith's writeup on the tilt effects of side and end loads on a curved blade
is now nearly complete; submittal is expected this week.
ASI significantly reduced the size of the "Parts Count Increase" lien
by restricting it to costs associated with the spring redesign and the pod
splitting, and LIGO accepted this. Only one minor lien now remains.
Actuators:
Nothing new.
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:
Nothing new.
Galling/Dusting Test:
Nothing new.
Other:
Ken Mailand and Larry Jones met with Jerry Knepper of 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.
Several problems exist having to do with size and processing/handling, which
are not insurmountable. Jerry is developing a ROM (rough order of magnitude)
cost for our budgeting purposes for both this task and a pathfinder cleaning
development task that we've planned.
Accu-Glass is developing quotes for our in-vacuum cabling needs.

AdLIGO Suspensions
Working on quad structure design and analysis with Calum and Tim.

1. We (Liyuan Zhang) have now interesting results on lab measurements of the
"LIGO I" HR point scatter. The measurements are quite clean, but we
must interpret !
2. I have refined a calculation of what the intensity noise induced by BS
motion through the RC standing wave field means for AdL. Infact
this may have been measured (at LHO). The up conversion only significantly goes
up a few 10s of Hz. This might be noticeable on AdL. More exact numbers need to
be used.l
3. Got around to enhancing (updating) my model of mode duality for distorted
"arm" cavities ( practically applied to the "mexican" hat
scheme for far advanced configurations). This is being tossed around those
specializing in this matter.

AdvLIGO PSL
===========
The mode matching from the master laser to the slave was
optimized and the high power laser was run in its injection-locked
configuration. The output power was 185 W. The output beam will be
studied with a pre-modecleaner. Part of the preparation for that included
development of an auto-alignment system.

I have finished the preliminary study about thermal noise with finite size
mirrors, and the optimization of the mirrors dimensions and beam size for
Advanced-LIGO (draft available in ligo.caltech.edu/~jagresti as
optimization.doc). Now I am working to include in this analysis the
thermoelastic coating noise and repeating all the calculations for the Flat-Top
Beam Profile. Moreover I am extending the equivalence relation between non
spherical cavities to the case of a cavity with non-equal mirrors.
