>From: Linda Turner - turner@ligo.caltech.edu>

43 file boxes of paper documents were scanned and converted to PDF files.
Finished the layout for the move to the new sub-basement location for the DCC archive records currently in the East Bridge storage room. The layout should accommodate all current boxes, records, and equipment. Ordered 100+ bankers boxes to box all documents in the sub-basement in like sizes to best use the storage units being purchased by PMA. While re-boxing, we hope to get rid of those things no longer needed, duplicates, and do general cleanup so that the new storage room better organized.

>From: Cleveland Mak <mak_c@ligo.caltech.edu>

Finishing up on the processing of GWDAW presentations.
Scanning Update - Scanning of Travel Expense Reports is now complete. Scanning has begun on Chronological Files.

Document Management System (Upgrade)

>From: Linda Turner - turner@ligo.caltech.edu>

Continued to work with George on the current DCC system documentation. Nearly all is completed. The only remaining task is final organization of all pertinent 2006 emails. For the hardcopy version, divider labels remain to be printed and inserted.

>From: Phil Lindquist – Lindquist_p@ligo.caltech.edu>

George Stokes is very busy assembling a couple of GigaBytes of documentation on the current system as well as information on the conversion to FileHold. We are still looking for guidance as to whom this information could/should be provided. Linda is assembling a shelf for hardcopy.
Larry Oliver, the president of FileHold (company with which we were working on previous upgrade approach), has provided a proposal for a revised DCC implementation, which I will distribute with my comments when I have a chance to review it thoroughly.

Completed and sent out reports for the Outreach Award, the Visitor Award and various other monthly reports.
Prepared a schedule showing the allocation of the first installment of the FY2007 award and sent it to the Office of Sponsored Research.
Prepared and submitted three Intra Award Cost Transfers. Note that account number LIGO.HSAS/1 NSFLIGO.FY02ON should not be used. This account was created in error by Project Accounting, and the system will not allow the account to be closed. The correct account to use for the fabrication of the HAM SAS is LIGO.HSAS/1 FYO2CA. Care should be taken to select the correct Award number, to avoid having to submit Cost Transfers.
Prepared a subset of the monthly financial reports for Hanford and Livingston task managers. This new report will include just the data for the two sites and will be posted at a separate site on the network. Access to the site will be password protected. Creation of the site has been delayed because of problems with the cooling system at Caltech.

SUBCONTRACTS MANAGEMENT (Jasnow, Salone)

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

An addendum is being issued to the RFP for the Advanced LIGO Pathfinder Optics. This addendum will cover the option of LIGO providing infrastructure, the possibility of proposing alternative approaches, and a specific definition regarding curvature measurement. Proposals are still due on January 19.

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

On January 9, GariLynn Billingsley and Ed Jasnow met with representatives of General Optics at their facility in Moorpark, CA, to discuss their schedule slippage on the polishing of the test mass optic. They stated that the delay had been caused by their need to build special fixtures in order to handle an optic of this size and weight. They submitted a revised schedule showing delivery of the completely polished optic by February 28. This new schedule will be incorporated into the contract by Change Order.
A meeting is being held today with a representative of E-FAX Corporate to explore the possibility of bringing the capability of electronic faxes to LIGO. Under this system, faxes can be received via e-mail. This would be especially convenient for people on travel.
A teleconference was held among Carol Wilkinson, Rod Luna, Ed Jasnow, and representatives from the seismic isolation effort in the United Kingdom regarding possible customs duties. It was agreed that Carol would compose a letter describing the seismic system as part of a scientific instrument so as to avoid customs duties. Additionally, it was agreed that all shipments would go to MIT, and that any parts that required cleaning would be sent from there to Caltech.

PROPOSALS and REPORTS (Lindquist)

We are assembling the end-of-December report for the National Science Foundation.

As reported last week, we are beginning to discuss the preparation of the proposal for Continuing LIGO Operations (FY 2009 – FY 2013). We will follow the usual process: propose an outline, assign responsibilities, and prepare a schedule. The target will be to have a complete draft by mid-July. Concurrent activity will include preparation of the Annual Report for FY 2007.

The NSF notified us today that they are scheduling a Total Business Systems Review (TBSR) of LIGO and associated Caltech business systems at Caltech February 27 through March 2. The NSF team will be looking at our LIGO reporting and budgeting systems as well as Caltech’s procurement, payables, financial reporting, property, and human resources processes. We are not sure yet how many of staff will be affected.

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

Summary of S5 Activities at LIGO Hanford Observatory (compiled by M. Landry)

Extended periods of forty to sixty mph winds last weekend kept both IFOs from locking for long period. Duty factors were down, particularly on H2, with H1 up 71% of the time, H2 65% for the week. Ranges varied broadly as has been the case over much of the last two months, 10-15Mpc on H1 and 5-7+Mpc on H2.

We're gearing up for a ~1 week commissioning break starting on Jan 22. Key tasks are H1 PEPI, H1 higher power/WFS bandwidth increases, and line mitigation on both machines. We'll endeavor to resume science-mode or near-science-mode running in the late evenings after the commissioning day ends.

Some S5 highlights from the LHO elog are bulleted below:

summaries: Tuesday maintenance, CDS maintenance,most recent range & duty cycle weekly, IFO maintenance
after an 11-day reprieve from ETMY chargeup/mechanical hangups, we had another event on H2
H2's PMC transmission has been falling. Significant power was clawed back in a Tuesday alignment tuneup, from 6.5W to 8.5W. H2 had trouble getting into CM mode after the Tuesday work, so an old PD calibration of the transmitted light had to be restored temporarily
periods of excessive H2 glitchiness were observed

Outreach (D. Ingram)
Outreach recognizes LHO's Josh Myers for coaching a LEGO robotics team at Christ the King School this winter. Josh worked with a handful of students weekly over a couple of months. Remember, LIGO is not LEGO.

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

S5 Run (Valera Frolov):

The science data taking duty factor was 79% for the week ending Thursday. A 39 hour long lock was achieved by the L1 interferometer after the recycling mirror optical lever laser was replaced (we were also lucky not to have a big earthquake during this period). As in previous weeks the downtime was due to seasonally high micro-seismic activity coupled with daytime seismic noise. There was very little loss of uptime during the night time. The binary inspiral range varied between 12 and 14 Mpc depending on seismic motion. Other activities this week included investigation of the long term main laser power variation, reconfiguring the reflected port beam stabilization, calibration line on/off test, and magnetometer noise investigation

CDS Computing (Lisa Bogue):

Fixed the script that generates the FOM indices for the S5 pages. Deleted and regenerated all of the existing indices to clean up any errors.
On-going scirun support.

Safety & Security (Rich Riesen):

All LLO site emergency lighting units were checked for proper operation. All fixtures are operational.
All LLO site fire extinguishers were checked for proper tags and pressure. All units O.K.
During this reporting period's site safety rounds, two trip hazards were found. Corrective action was taken.
Found no laser safety concerns this period.
Working on the LLO FY07 property inventory.

Controls and Data Systems (Bork)

LIGO Activities:*

- In the process of building the Test Point manager (TPM) code for later
OS revisions, Alex found a memory leak problem, which may or may not
have been the cause of TPM problems noted at LHO a while back. The code
has been fixed and loaded at LHO. At some point, a decision needs to be
made if and when the new code should be loaded at LLO.

40m Lab Activities:*

- The equipment and software for the new alignment system is ready and
will be installed over the next few days.

Enhanced LIGO:*

- Jay has put together an integrated controls drawing (DC readout,
suspensions, seismic) for the OMC. We are working off of this toward
verifying a cost estimate. We will also have to take into account some
CDS infrastructure pieces that will be needed to support this, including
reflected memory network connections, timing system, etc.

40-Meter Interferometer (Weinstein)

IFO commissioning, Electronics, controls, computers:

Last Thursday, Steve vented the 40m (with no incident) in order to install the squeezer pickoff mirror and to search for clipping in the AS in-vac beamline.
Kirk, Osamu, Justin, Steve, and Rana started looking for the clipping. They locked the input MC in air and observed significant clipping on the TT-PZT1 sterring mirror in the BS chamber, just after the SRM. They also noted that the beam exiting the IFO is ~1.5 cm off from the center of SRM. This explains a lot: the AS beamline and TT-PZT mirrors were aligned using fiber-fed laser light from the OMC back to the IFO, under the assumption that the IFO beam is centered on the SRM. Since it isn't, the beam clips on TT-PZT1.
So, the crew moved the TT-PZT1 steering mirror to eliminate the clipping there and further downstream (at the OMC MMT). Steve set up a jig to make a parallel transport of the mirror; it was translated parallel to the mirror surface by ~1 cm.
Further searching for clipping downstream of the TT-PZT1 sterring mirror did not yield anything significant. They then were able to lock the OMC.
Osamu and Go swapped out the old, nearly immobile squeezer pickoff mirror with a new rotating version, which works much better and swings into place in 1-2 seconds.
After some effort, they rebalanced the optical table (which is on a single-leg stack) with some aluminum ballast, and completed all the alignment of the various beams (to the squeezer, the OMC, and the in-air AS RF beamline). They checked that when the pickoff is swung out of the way, it does not clip the beams going to the OMC or to the AS RF beamline. Rana and Justin checked that the beam was well centered on all the in-vac optics.
After a final check by Steve, Rob, Osamu, Go, Rana, and Justin, including the installation of some beam dumps in strategic places, they sealed up the vacuum envelope and began pumpdown on Tuesday afternoon.
They left the envelope at 0.9 torr overnight, to see if any static charge buildup on the mirrors would discharge via the Paschen effect. Results were inconclusive, but it doesn't look like the mirrors changed much overnight.
On Wed morning, Steve turned on the turbopump and completed the pumpdown with no incident.
Within hours, the input MC, arms, Michelson, and OMC were re-aligned and locking up.
Kirk is adding extra zero/pole filters to all the LSC whitening board channels.
Rolf and Alex have installed a new computer, networking, and software for the new IFO alignment system, and commissioning will take place over the next few days.
Royal made some new cables for the ETMY oplev readout electronics to replace some inadequate ones.
Justin has been busily fixing and improving our scripts for maintenance and control of the interferometer, including: autoBURT, PSLwatch, trianglewave, LIGOenv.pm, LIGOio.pm, ifoTest, and PERL5LIB.
Justin noticed that BURT wasn't taking any snapshots because we had run out of subdirectories for it to use after 2006. There was no 2007 directory. So we have no BURT snapshots for the first week in 2007. Rana wrote a script to generate subdirectories up to the year 2200. Meanwhile, Justin fixed the autoburt script so that it would make the directories it needed, automatically.
Rana, Justin, and Kirk have been working on the smooth PRFPMI locking.
Tobin and Kirk measured and adjusted the FSS and MC loop UGFs and gains.

Vacuum squeezing:

Now that the in-vacuum squeezer injection optics are installed, Go has designed the layout for the injection optics (including steering mirrors, faraday isolator, mode matching telescope, QPDs and DC PD), and the alignment procedure.

Lab Infrastructure, Bake lab:

Larry and company installed a new network wireless transmitter in the lab with much more power, so we can hope to access medm on our laptops down the arms.

Thermal Noise Interferometer (Black)

We are currently waiting for the new mirrors with aperiodic coatings. Innocenzo reports a delay with the mirrors, which Nazario thinks may be due to a deficiency in the cap layer. The people at LMA are running some tests now, and they expect to have more information in the next few days.

In the mean time, we are performing some basic lab maintenance, including tool and safety inventories, cleaning the HEPA prefilters, etc. Sebastjan Meznaric, a Caltech undergraduate, has joined the TNI team, and we are getting him started with readings and safety orientation.

Greg Ogin is working on the spot size measurement.

LASTI (Ottaway)

Initial LIGO Suspension Thermal Noise Testing (Contributed by Gregg Harry)

Visitor Steve Penn and I got the initial LIGO suspension thermal noise experiment operating again. This time a clamp inspired by Virgo is being used. This clamp system uses harder tool steel to clamp the wire, and larger screws to allow for higher torques. It performed well in single wire tests at Hobart and William Smith.

The clamp was installed and the experiment pumped down to vacuum. Finding and measuring Q's on wire modes is the next step.

HAM SAS Installation

This week we used the HAM SAS elevator to succesfully extract the optics table and the old support table from the Yend HAM. The HAS SAS unit minus the optics table is now positioned on the elevator and ready for installation into the HAM chamber. Virginnio and Alberto are currently testing and calibrating the LVTDs and actuators. In addition to this the in-vacuum HAM SAS wiring is being installed.

Over the weekend we are hoping to do a fit check of the HAM SAS in the Yend Chamber

ISI

We have installed an optical lever to independent check the off- diagonal terms of the stiffness matrix. Stay tuned for the results.

Followed-up with Globus XIO team regarding LDAS managerAPI coredumps when using Globus threaded libraries.John Bresnahan (XIO programmer) thinks there is some race condition occurring, but not sure from Globus code or LDAS code. Action item: Michael Samidi will re-run LDAS managerAPI on one of Tandem systems with valgrind once the cooling problem is resolved.
Filed Globus PR related to GSI authentication failure on Opteron systems. No response so far.

GRID APPLICATION DEVELOPMENT:

Still running 3 full HIPE workflows with local cache and clustering at UCSD for meeting the first OSG milestone which is using 25 slots at UCSD continuously in one week. The first workflow has completed 93% (a total of 1571 jobs). The second workflow has completed 40%. The third workflow has completed 1%. From Jan 2, 2007 to Jan 10, 2007, the workflow has been running continuously even though at some points it is using less than 10 slots. Discovered Pegasus parsing problem when running nano HIPE using SRM/dcache at UCSD. Pegasus kickstart program doesn't parse correctly SRM URL format with the ? sign in front of SFN. Discovered Pegasus limitation when using vds.transfer.links property to run full HIPE at LDG CIT cluster. With this property, symlinks are created instead of physically transferring input GWFs from CIT repository. However, all third party transfers (LALapps executables and GWF calibration files) have to be copied manually from submit host to remote workdir. Met with Kent Blackburn and David Meyers to discuss some suggestions to improve the conference paper co-written with Ewa Deelman et.al. (ISI). The paper talks about the issue of optimizing disk usage and of scheduling large-scale scientific workflows such as full HIPE with limited storage resources such as OSG resources.
On Friday, Jan 12, 2007, Michael Samidi will visit ISI and meet with Pegasus team (Karan Vahi and Gaurang Mehta) to resolve item #2, #3 and job clustering problems.

Patrick Sutton

LIGO-Virgo Project IIB (joint analysis with real data exchange): I created segment and data quality veto lists for the LIGO detectors during the period of Virgo weekend science run 1 (WSR1), 2006 Sep 8-11. I also created copies of h(t) frames with a "secret" time shift for each site, as desired by the LIGO-Virgo joint burst group. Details are available at http://ldas-jobs.ligo.caltech.edu/~psutton/ligovirgo/project2b/data/ and from the LIGO-Virgo elog.
Coherent analyses: I've started drafting a paper with Stephen Poprocki comparing various coherent burst detection statistics. I've also spent a lot of time working with Poprocki (who's visiting Caltech) as he develops a technique for source position estimation based on comparing measured all-sky likelihood maps to maps one would expect to get under different assumptionsof true source position, polarization, and other properties.

Hanford:
(Christine)
- Spent the weekend rack mounting all the new equipment in the server
room. In the end I was unable to power up most of the new equipment
because the new CDS UPS is not functioning yet and until that is working
I can't use the old CDS UPS.
- Set up two more laptops for Operators, a MAC and a WinXP.
- Finished some paper work from past purchases for Ruth for an audit.
- I've received two checks from a class action settlement against Dell
for over charging on taxes. Ruth told me how to send the checks to the
Caltech cashier for deposit to the Hanford Data/Computing account.
Spent time filling out paper work for that.
- Helped a user with a quarantined inbox. Helped another user whose
mapped network drive was no longer visible.
- Re-mounted the ldas and application server file systems to several
Solaris machines and to the Control Room Linux machine. After the power
outage on Christmas night these file systems were not re-mounted. These

-Continual work on procurement and licensing issues.
Tracked down some problems with the Dell orders and have resolved them.
Still working the the mathematica license renewal with campus.
Distributed a few more matlab licenses.
Procured a number of items to help keep some of the computers running
during the air-conditioning problem.
Procured misc. items for different groups.
-Assisted PMA in working out issues on the different moves for offices
and labs.
Worked on some of the physical moving of equipment in preparation for
the office changes.
-Worked a number of cabling items at different locations.
-Spent time keeping things going during the power outage and the
air-conditioning problem. The air-conditioning issue will continue for
another week. We do have the core items on the GC server room running.
Thanks to all those that have helped and are helping monitor things
(Mike, Christian, Veronica, Erik, Dan and Phil). With the cooler weather
and some chilled water to our local unit we are now able to keep things
physically secure without someone being here all the time to watch over
the equipment. We still have to extend the schedule for people but it is
working out.
-Working on the 40M computer replacement. I will probably move the unit
over to the 40M and finish working on it over there.
-Assisted the DCC with a number of small issues.
-Working on the new mail server and home account system. I've discovered
a few gotchas and should have them worked out pretty soon(depending on
jury duty).
The samba system will have to be changed but the testing of the new
system has shown a good improvement in performance.
Still have a number of tests to run on the mail servers but it appears
all of the show stoppers have been taken care of.
-Installed a number of h/w items, with Mike, into the racks. The
shuffling of equipment has started.
-Added a number of new accounts and cleaned out a couple of old accounts.
-Worked a couple of backup issues. Still need to do some testing to make
sure things are working properly.
-Worked the spam filters with Mike and Christian.
We are still filtering out over 10K messages/day on the main mail server.
-Regular assistance with minor items such as printer jams, restarting
processes on end user boxes and clearing out tables.

Advanced LIGO SystemsCDS

CDS Infrastructure:

From: Rolf Bork rolf@ligo.caltech.edu

Continued work on design req. document. Met by telecon today with several people at the sites to get their input for functional requirements. I'm tentatively planning on visiting the sites the week of Feb. 5 to flush out this document and the resulting Conceptual Design Doc. with people there.
Alex has continued work on our Simulink to CDS code generator. Subsystem parts may now be built/nested to any level (previously only supported one level). Also, work is in progress to allow a different code model to run on each CPU of a multi-CPU computer. As a test, Alex was able to run the MIT vacuum squeezing code at 32KHz on one CPU and the HAM SAS code on another CPU at 2KHz concurrently, sharing the ADC/DAC I/O resources. The data acquisition and GDS parts still need to be checked out.

Seismic:

Several of us will be traveling to MIT over the next two weeks to finish installation of the HAM SAS controls and the triple suspension system controls.

ISC:

Work has progressed on the development of an in-vacuum DC Readout Diode and a Thermal Actuator to be used in the mLIGO Output Modecleaner System. A schematic for the prototype detector has been prepared and the associated PCB is being designed. Due to size and weight constraints, the DC detector circuit board is being made as small as possible. The DC diode is to live in a small laser welded vacuum tight enclosure containing a trace gas for leak detection. The diode electronics enclosure also serves as a mount for the diode element as well as providing a beam dump and stray light baffle.The thermal actuator consists of a custom designed vacuum compatible aluminum nitride heater element that provides about 2 watts of heating capability. The heat flows uniformly and symmetrically into an aluminum optic holder to accomplish the length actuation.It is a desire for the system components to maximize radiative cooling to avoid thermal distortion in other system components. With this in mind, a company has been selected to try some experimental vacuum-compatible coatings to the aluminum surfaces of devices to be cooled. The emissivity of the surfaces can be increased by a factor of ~8 beyond bare aluminum. A small vacuum test chamber will be used to verify the effectiveness of the coatings prior to design completion. Estimates for heating and cooling times have been made as well as conductive heat transfer modes into the output modecleaner bread-board.Another new aspect to this development is the use of "disposable" electronics modules to enhance modularity and vacuum compatibility. The laser welding, coatings, and leak checking will be done by a list of outside vendors that have been selected based on their expertise in these areas. It is believed this will help reduce cost and increase reliability overall. The same techniques can be used for other in-vacuum electronics in the ISC system and other applications.

Prestabilized Laser

From: Peter King <pking@ligo.caltech.edu>

I spoke with Benno about the interface that will be provided with the front-end laser. The laser will be under control using the Beckhoff automation interface. I have obtained the Beckhoff hardware and software information from Christian and have a call into Beckhoff HQ for pricing and other information. Then the aim will be to test communications between EPICS and the Beckhoff software.A Ge photodiode was installed in a general purpose photodetector board and the circuit is being debugged.

Seismic Isolation

Announcements

HAM contract status

HPD will probably choose the 3 post design,
PDR is Thursday, Jan 11, 8:30 - 4 at HPD in Boulder, CO. It will not be phone-cast.

Ken is inclined to keep the table flatness at .010" , and will email HPD as such. He will include info from Arland tool that tolerance for a machine cut for BSC table (front and back) is not too hard. Dennis will see if specs from Initial LIGO shed light on req's.

Progress on the BSC

cap sensors working better
power supplies fixed
new compliance matrix measured, seems better
radius moved from 8 m to 100 m (want 500) one corner comes out different than others in shim size and in mechanical response (seems well damped, which indicates rubbing is likely)
ASI code predicts shim changes for good corners of about .05" (about a mm) -- load change can not explain this

Possible culprits:
- could still be interference;
- disp sensors could still be off ;
- could be something goofy in the plan
- -- but interferance is most likely.

Rich will do a few more test, and then remove 2 actuators from interfering corner and inspect them. Maybe use a sticky thing to remove contaminants from inner gaps? Suggestions for changes to the actuators for Advanced LIGO and single stage HAM:

open up the gaps on the actuators in non-magnet transverse direction to something like 5 or 8 mm.increase throw distance a bit
replace the interior gap which is now 2 flat plates 45 mils apart to a larger typical gap with 4 Aluminum nubs at the corners with the 45 mil gap so that (a) reduce the places where contamination might be to be able to cause problems and (b) make it possible to visually inspect the 4 close points. Once the system has been made to stop rubbing, and the compliance matrix measured, we need to get the new shims made.

additional cap sensors?

Brian will send email to Ben Abbott and also ask for a few more 1m cables

pods at LLO - clamps/ lockers

Brian O will check up with Joe Hanson, the new clamps should be done soon. Not sure about status of the locker/ unlocker program which Shyang is working on.Rich M to check the boards and cables for the GS13 to be sure that LASTI has all the parts needed to fix the GS-13s when they come off at the clamp replacement

cleaning

Ken got quotes back and is talking with Dennis about options (this is contract sensitive)Feedforward at Stanford

additional measurements needed before venting.
Brian L wants to get a new Advanced LIGO style control computer running at Stanford

Subject: minutes of the HAM-SAS weekly meeting, 1/10/2007

minutes of the HAM-SAS weekly meeting, 1/10/2007
David S., Ben, Dave O., Ric, Alberto, Virginio, Dennis

1) LASTI

old optics table & support table are out -- major interference, but worked around this problem
HAM-SAS being installed on the elevator -- to attach to elevator, need to attach with shims between HAM-SAS & elevator (planned) -- need 16 longer bolts (class B), because incorrect holes were selected in design -- ordering for overnight delivery & then overnight air bake
alternatively machine proper holes in shim plate since cables arrive late

Cables out of the bake oven in two batches (Fri & Mon) -- slip of ~3 days

Missing (class B) bracket being remanufactured & cleaned & air-baked by G&M

2) Electronics

Virginio mounted LVDT boards into rack -- will make a special cable for vacuum feedthru pin flip & will then test -- EPICs channels seem to give correct results -- need more D25 cables

Baking of accuglass cables -- batch out of vacuum oven Thu (at LASTI friday) -- cables for stepper motor out Mon (at LASTI Tue)
stepper motor drivers received
quad photodiode IF bds completedGuralp IF bds completed
everything is on track to support the CDS install/test trips
Jay & Rolf next week, Ben the week after

3 coil drivers are in the NIM crate -- 2 more coil drivers modules have been(?) shipped from Italy (Marwan); these units need to be put into a NIM module (need 4 plus 1 spare) triple: will only use M1 stage (issue with supporting the lower stages with the current infrastructure) -- this is deemed acceptable

Suspensions

From: Janeen Romie <janeen@ligo-la.caltech.edu>Enhanced/Advanced LIGO

Working with Chris & Calum on OMC design. Calum's found spare IMC intermediate blades for this first OMC prototype.

From: k mailand kmailand@ligo.caltech.edu

I will be meeting with Calum and Ian this week on the progress on installation tooling, and also to set priorities. I did a cost estimate on the baked stainless baffles for Mike and availability of alt. material gages; also a follow-up on the ESD mask progress, currently in final lapping after EDM and a stress relieving bake cycle.The CES shop is continuing work on the arm style, and LASTI conveyor style, installation tooling,also the elevator mechanism for the lower quad, and the fixture modifications for the tooling interface.
Most of the final shop drawing details for the initial assemblies will be complete 1-12.

Core Optics

From: GariLynn Billingsley <Billingsley_G@ligo.caltech.edu>

We have received two quotes out of 9 RFQs for the LASTI compensation plate. Looking into acquiring inexpensive but suitable glass for this effort.

We are answering some questions about the pathfinder procurement, nothing surprising yet.

Ed Jasnow and GariLynn Billingsley visited General Optics on the 9th, to check up on the progress of the polishing of the LASTI TM. GO estimates an end of February delivery, putting the TM (with ears bonded) at MIT around the beginning of May, ready to hang by the end of June, after the bonds cure. Helena is working to be sure that LMA is ready to receive and coat the LASTI TM as soon as possible upon receipt. We will modify the contract with GO to reflect the new promised delivery date.

From: Helena Armandula ahelena@ligo.caltech.edu

Advanced LIGO Coatings - First ContactStarted testing methods to apply and remove First Contact on a large mirror. I am using an old pathfinder LIGO I substrate. The results are good but not perfect; the techniques and the tools I am using need to be refined.

Auxiliary Optics

From: Michael Smith smith@ligo.caltech.edu

SLCI compared Peter Fritschel's scattered light analysis in the AS port with my analysis (see http://www.ligo.caltech.edu/~smith/AOS/SLC/T070003-00_AOS-P.F.-comparison.pdf . The two different approaches are equivalent. The biggest difference between the magnitudes of our scattered light calculations is the value used for the BRDF of the Brewster's window surface. I have contacted Newport Corp and TMA Technologies; they will try to give me some information on the back-scattered BRDF of uncoated superpolished windows.

INITIAL ALIGNMENT

I am in the process of writing the Initial Alignment Conceptual Design Requirements document.

COST UPDATE

I am in the process of updating the cost estimates for ADLIGO AOS.

Enhanced LIGO

I made a layout of the OMC in ZEMAX for Sam Waldman.
