STATUS OF LSC MOUs (Lloyd)
Andrews, Montana and Rochester MOUs were resubmitted with the revisions requested by the review panel. These revised MOUs were posted for review by the panel.
DOCUMENT CONTROL CENTER (Turner, Mak)
FINANCIAL SYSTEMS (Funaro, Brambila, Kaufman)
>From: "Funaro, Catherine" <Catherine.Funaro@caltech.edu>
>From: "Brambila, Ruth" <Ruth.Brambila@caltech.edu>
- Completed several change orders on purchase orders and submitted to vendors.
- Responded to inquiries from vendors, staff, and researchers and provided assistance and answers on orders.
- Re-directed mis-delivered order to the appropriate department on campus.
- Completed change order #11 to Corning and submitted to vendor.
- Completed the change order to Praxair that was done in my absence.
- Placed the SRS order for Rana, and followed up on the delivery of the second optical table, which arrived on campus last week.
>From: Florence Kaufman <fkaufman>
- Completed and posted the monthly report for operations as of the end of August on the network.
- Started work on training my replacement Karl Oracion.
- Worked with Karl and sent out reports for three Discretionary Accounts, Outreach Award, Award form University of Wisconsin, Low Noise and I2U2 Awards.
- Financial reports can be found at: http://docuserv.ligo.caltech.edu/~fireport. (For passwords contact Florence)
SUBCONTRACTS MANAGEMENT (Jasnow, Salone)
>From: Gina Salone <gsalone@ligo.caltech.edu>
- Modification No. 18 was issued to the Praxair contract for LN2 at LHO. This extension was to carry the contract to the end of S5, so that an RFP for a new contract for LN2 can be issued with no restrictions on deliveries.
>From: Ed Jasnow <jasnow@ligo.caltech.edu>
- A teleconference was held yesterday on the subject of customs requirements for material expected to be received from overseas for Advanced LIGO. Participating were Carol Wilkinson, David Shoemaker, Ann Margaret Chrisney, Gina Salone, Cleveland Mak, and Ed Jasnow. Among the issues discussed was the usage of the correct import brokers and the issuance of Caltech powers of attorney. It was agreed that the current powers of attorney would be extended to five years for the brokers in Los Angeles and New Orleans, since they had performed effectively in the past. David Shoemaker agreed to research the name of MIT's preferred broker, since it appears we did not use that one on the test mass from Glasgow. Additionally, upon his return from medical leave, Rod Luna will research the names of potential brokers in both Seattle and Portland. Also, a draft of a cover letter to obtain a blanket waiver from U.S. Customs on scientific instruments has been distributed to all attendees of the teleconference, plus Ann Bussone of OGC.
PROPOSALS and REPORTS (Lindquist)
Completing the proposal for continuing operations (FY 2009 FY 2013). The proposal budgets have been sent to the Office of Sponsored Research. OSR had a number of suggestions that we will be addressing over the next few days. Rana proposed some revisions concerning QND section which Dave Beckett is assessing for impact, and Dave will provide before and after images to be considered for inclusion in this next go around. All such proposed changes will be carefully controlled and provided to the Director’s Office for blessing.
The Annual Report for current Operations has been sent to the NSF as an “interim Report on FastLane. We used the “Interim Report” category because FastLane does not currently have a place for us to submit an Annual Report for FY2007 (this appears to be a bug in FastLane...).
The LIGO Visitors program was officially over July 31, 2007 (subsequent visitors are covered under Operations), and a Final Report has been prepared by Stan Whitcomb. This reports was sent to the NSF via FastLane this week.
I have sent out a reminder to all the usual suspects concerning the monthly report for the end of August. Inputs are requested by Wednesday, September 12. We will submit the report by the end of next week.
I have begun preparing the budgets for Operations in FY 2008. I am trying to reconstruct all the “wish list” items beginning with last years budget version 4.0. These budgets will be used to prepare the Work Plan for FY 2008 to be submitted to the NSF at the end of this month.
CHANGE CONTROL/CONTINGENCY MANAGEMENT (Lindquist)
- CR-070007 requests funding to cover increased design and fabrication costs for SEI HAM Prototypes. Need to first perform an assessment of year-to-date budget and wish list coverage. A revision to the request is expected.
HUMAN RESOURCES (Akutagawa)
>From: Cindy Akutagawa <cindy@ligo.caltech.edu>
- No report -- Cindy is out.
Quality/Safety (Tyler)
>From: Bill Tyler tyler@ligo.caltech.edu
Nothing significant to report this week.
LIGO
Hanford
Observatory (LHO) and Interferometer Operations (Raab)
Summary of S5 Activities at LIGO Hanford Observatory (compiled by K. Kawabe)
Very good week as the stat shows. The duty cycle of H1 and H2 (from Thu. 30/Aug/2007 to Wed. 5/Sep/2007) were 88.8 and 88.7 percent, typically with 15.5 to 16 Mpc and 6.5 Mpc binary range, respectively.
Summaries: Range and Duty Cycle update. Tuesday maintenance summary.
Highlights from the LHO elog:
LIGO
Livingston
Observatory (LLO) and Interferometer Operations (Giaime)
S5 run (Valera Frolov):
- The S5 data taking duty cycle for this week was 73%. The bns range was around 15 Mpc during the quiet time and 13-14 Mpc during the daytime, when power was reduced from 8 W to 5-6 W. One of the piezo actuators of the reflected beam stabiliztion system failed on thursday night and was replaced on Friday. There was sum check error on one of the frame builders which was found during the weekend and resolved by rebooting the machine. There was no loss of science data due this episode.
- During the Tuesday maintenance the interferometer input beam mode was characterized at different power levels. It was found that beam shape becomes significantly distorted at high power possibly due to the thermal effects in the Faraday isolator. This is a continuing study of the mode matching into the interferometer.
CDS Computing (Lisa Bogue)
- Submitted 2 documents to the DCC. T070215-00-D, Recovering LLO CDS Computing from a Partial Power Outage and T070216-00-D, Recovering LLO CDS Computing from a Full Power Outage.
- FY'08 budget planning.
- Working with the t1000 hardware.
- Fine tuning sol10 jumpstart server.
Livingston Outreach (John Thacker):
- Made preparations for and conducted docent training on 4 exhibits.
- Revised Docent Manual.
- Drafted procedures for scheduling field trips, professional development programs and public tours.
- Sent confirmations to field trip and professional development requests.
- Updated calendar.
- Developed a light activity using card stock (eye glasses) and fiters of different types.
- Worked on transferring information to the SEC shared folder.
- Established research dates in exhibit hall for Tulane volunteer (Psych. Tulane).
- Next Phase committee work; update of committee document.

40-Meter Interferometer (Weinstein)
- We had two (unrelated) computer failures this week, both of which brought down the suspension controllers. Alex traced the first, on Friday, to a power supply failure on the c1dcuepics computer; he replaced the supply and the systems came back to life. The second was on Tuesday, and Alex traced it to a failed disk on c1iscepics. He pulled out that computer, transferred the iscepics process from it to c1dcuepics, and brought it back up. Rana did a BURT restore to get everything working again. Alan got the nightly disk backup working; the second time, we needed help from Dan Kozak.
- Rana is exploring the origin of the RFAM that we now know is present after the Mach Zehnder (and presumably caused by it). We now have a reasonably reliable monitor of it in the MC reflected beamline.
- Elena and Andrey are working on understanding the coherence between accelerometers on the floor and the suspended optic motion, in order to implement some feed-forward noise cancelling.
- Steve is diagnosing problems with the vacuum N2 readback, which should trigger an interlock if it falls too low, but doesn't.
- SURF Elena Gaspari and grad student Andrey Rodionov went through the 40m safety training with Steve.
- Valera is coming on Monday to work on the autoalignment system and the OMC.
- Bram is coming to work on the tip-tilt mirrors for eLIGO.
- Rob and Tobin are back.
Thermal Noise Interferometer (Black)
- Reinstallation of the optics continues after the move. All of the steering mirrors outside the vacuum and a few of the steering mirrors inside the chamber have been installed, and two of the mode-cleaner mirrors have been suspended. So far, the only problem has been the discovery that the table on top of the in-vacuum stack is not level, but we didn't expect to preserve that anyway. It's an easy thing to fix.
- The south retaining wall has also been installed, greatly improving laser safety over the old curtain arrangement on that side.
LASTI (Mittleman)
BSC ISI
- This week we had both stages floating long enough to balance both stages and install both sets of locators/lockers. All of the lockers were then engaged and we have moved onto installing the actuators. All of the small actuators have been installed. We then installed the vertical GS-13 pods, finishing the installation of the seismometers.

Laboratory Computing (Anderson)
FROM LAST WEEK's REPORT ....
LDAS Software Systems (Lei)
- (ML) cmonClient - working on PR 3190 - new page to support cleanup of ldas jobs and logs and updating of these resources.
- (ML) cntlmonAPI - PR 3190 - added some code to return log, purge and cleanup info and execute client commands to update these vars.
- (ML) Testing:
- no system test and weekend test due to power shutdown making /scratch not available.
- filed PR 3203 against dbaccess as it complains of gds_trigger non-unique process_id but process_id in gds_trigger is not a unique key field. But John Zweizig claims this is a dmt error.
- updated diskcache resource STAT_TIMEOUT from 5 to 30 in memory per Igor's changes.
- /ldas/bin/cmonClient does not work in a 64 bit environment as wish was not compiled with 64 bit ? And of course /ldcg/bin/wish cannot load 64 bit tclglobus so use of globus is out. I remember Ed said cmonClient can only be run on the user's desktop after 64 bit build but I need to confirm with Ed. A PR has been filed for this issue.
LDAS System Administration (Anderson)
Caltech
(Dan Kozak)
- Did work to support power test and chilled water outage in Powell-Booth (moved export-dev T3 to UPS power, shutdown and restarted tape drives and silo).
- Talked with Xavi about h(t) situation, am now waiting on list of files from him.
- Did lots of 6140 work. Final(?!) filesystems now built.
- Replaced bad frames on node153 & node154.
- Called in opterondata-cit crash to Sun.
- Did tape lists for shelf storage at LHO/LLO.
(Phil Ehrens)
- Ongoing support of MOU Review Website.
- General certificate management tasks.
- Contacted JMC fans regarding purchase of replacement fans for cluster nodes. No reply from them so far.
- Researched readily available materials appropriate for use as cluster node air filters. Best candidate so far is "white ScotchBrite", which has good mechanical characteristics (free-standing) and good anecdotal reports of use in this application.
MIT
(Fred Donovan)
- Some nfs (v4, security) problems on osg-ligo cluster -- /etc/hosts related (?); purchase some disks; with Murali got condor & condor_probe reporting working again osg-ligo.
Livingston
(Igor Yakushin)
- Restarted failed segment replication at CIT.
- Changed ::STAT_TIMEOUT to 30 seconds in the /ldas_outgoing/diskcacheAPI/LDASdiskcache.rsc to deal with "Could not execute lstat()" error. An attempt to do it in cmonClient crashed it.
- Working on moving version 1 DQ segments to version 0 since version 1 is reserved for coalesced segments.
(Dwayne Giardina)
No report
Hanford
(Greg Mendell)
- The S5 SFTs generated from C03 hoft data for the first year of the run are on the nodes and published into the archive at CIT. These SFTs are available via LDR, and instruction have been sent to the CW group on how to find the files at CIT, how how to transfer them, for example to AEI.
(Ben Johnson)
- Replaced batteries in a 2kVA UPS (powering the 4600) and in a 5kVA UPS (powering 6 T3s). The 2kVA is ok, but the 5kVA is still has blinking battery fill lights. The latter is powering the T3s though, and it does "test".
- Getting Solaris 10 installed on the X4500 has been very difficult, either with SOl 10 U3 install CD or the OpenSolaris n70 installer (I'll ultimately go with Sol 10 U3). Apparently, ZFS really takes over a disk and completely eliminating the EFI partitions it creates is a chore. I've had to manually "format->fdisk" the drive, and manually create a UFS filesystem on it.
- Participated in the CDS Cybersecurity review as a reviewer and as the secretary.
- All h(t) data from Livingston to Hanford has caught up with real time (minus publishing and LDR latency). Still waiting to start h(t) transfer from CIT.
General Computing (Wallace)

- Reconfigured the IDS system at LLO to account for the new mirror ports on the core switch.
Hanford
(Christine)
- Worked a little with Mike to learn about the Primavera/Prism/VPN server that he set up for the Advanced LIGO group.
- Re-built a laptop for one of the Advanced LIGO contractors. The laptop was having problems and most of the application software needed upgrading anyway.
- Helped a user with email problems. There was a poorly formatted message in his Inbox and Thunderbird couldn't download the message.
- Worked with Technical Support at Symantec to fix the Veritas backup software. No fix yet, I just sent all the core dump and messages files to the support person.
- Ordered another Sun V125 server to use as a back up application/license server.
Caltech
(Mike)
- Christian and I worked on assembling a server rack mount unit to add to B/A server room 18. We also installed a new UPS plus transformer in this unit as well.
- Worked in B/A server room 19 started swapping out servers into another rack mount unit to install another new UPS plus transformer. This is a continuous project.
- Worked up at LHO with Christine to help setup and configure a server for ADVLIGO Carol’s group. This also consisted of setting users workstation to connect to the new server. I also setup a VPN server to grant users from the ADVLIGO team an offsite connection to the Hanford network.
- Worked with Larry in trouble-shooting the backup mail server.
(Christian)
- Helena - Created a backup of Helena¹s laptop.
- Julie Hiroto- Created a backup of Julie¹s workstation and installed new Thunderbird mail client.

(Larry)
- Working a number of procurement items. Presently, waiting on some final quotes for the SUN systems. Placed orders for workstations, edge-switches, UPS units, print and a plotter, and other misc. items. Delivered items that have arrived.
- Did the close out of a number of visitors and students that have left.
- Worked/working with Mike on the UPS installation and equipment swap in room 19.
- Spent time getting the backup mail-server on-line. Fortunately, Mike had a spare card that worked as a replacement for the one that had failed on the unit. Stuart is taking care of the replacement and will supply us with a new card matching the one removed.
- Modified a number of accounts and mail aliases to accommodate different user requirements.
- Installed more application s/w on the sandbox units.
- Worked on some plotter issues. The main problem is that the unit just doesn't have enough memory to handle some of the jobs being sent to it. Christian is working on getting more memory installed and a newer unit has been ordered.
- Working on a couple of replacement installations.
- Regular end user support.
AND THIS WEEK's REPORT ...
LDAS Software Systems (Maros/Lei)
- Starting to investigate what it would take to split the tclGlobus package into client and server packages to facilitate client applications which need to do certificate based authentication.
- Continuing work on integrating tests into the distribution. Currently working on integrating complex_data.tcl, database exception and putStandalone system tests.
- The changes for allowing cleanup to happen immediately via cmonClient (PR#3190) have been committed to CVS.
- Version 1.9.39 was used for system testing. It was observed that the fracc6.tcl system test did not run. Examination revealed that the script was run in a directory for which the ldas user did not have read access. A new option has been added allowing the temporary directory to be specified on the command line.
- Modified some of the system tests to improve reliability.
- (ML) cmonClient - working on PR 3190 - new page to support cleanup of ldas jobs and logs and updating of these resources.
- (ML) cntlmonAPI - PR 3190 - added some code to return log, purge and cleanup info and execute client commands to update these vars.

- Working on moving version 1 DQ segments to version 0 since version 1 is reserved for coalesced segments.
- Disk id 9 in 3511-3 failed on Monday morning. For some unknown reason the rebuilding of the array on the hot spare takes an unreasonable amount of time: it started on Monday at 10am and is only 90% complete by now (normally it should take ~3 hours). Received the replacement disk from SUN. Waiting for rebuilding to complete before replacing the bad drive.
- Working on coalescing segments in the segment database.
- During weekends disk2disk stopped archiving fb1's raw frames since they failed FrCheck. That suspended createRDS, segment publishing, online jobs until disk2disk was reconfigured to take fb0 data instead. After daq process on fb1 was restarted, fb1 started producing good frames again.
(Dwayne Giardina)
- Tape eject for shipment to CIT.
- Tape storage eject.
- fb1 /frames problems over the holiday weekend. files from fb1 failed FrCheck. we temporarily reconfigured disk2disk to use fb0. after Lisa restarted the DAQ process on fb1, the files passed FrCheck.

Hanford
(Christine)
- Worked a little with Mike to learn about the Primavera/Prism/VPN server that he set up for the Advanced LIGO group.
- Re-built a laptop for one of the Advanced LIGO contractors. The laptop was having problems and most of the application software needed upgrading anyway.
- Helped a user with email problems. There was a poorly formatted message in his Inbox and Thunderbird couldn't download the message.
- Worked with Technical Support at Symantec to fix the Veritas backup software. No fix yet, I just sent all the core dump and messages files to the support person.
- Ordered another Sun V125 server to use as a back up application/license server.
- Put together some information for Larry to present at the LIGO Cybersecurity review.
- Worked most of the week on getting a new laptop set up for an Advanced LIGO contractor. Getting Primavera and Caltech's Discoverer working is not easy. The fix for Primavera turned out to be pinging the server some how caused the client software to finally connect. Still working on getting information to set up Caltech's Discoverer.
- Tried to re-build a laptop that had started acting flaky, but have been unable to re-format the disk or to re-install Windows. Will try replacing the hard drive to see if that is the problem.
- Still providing information to Veritas support trying to get the tape backup software working. I've had to download and install some software from Veritas that does debugging.
- Beginning Mon. Sept. 10, I will start blocking off-site access to the un-secure POP mail ports. This will require every one to use SSH to access their email from off-site.
- Other misc. user support.
Caltech
(Mike)
- Christian and I worked on assembling a server rack mount unit to add to B/A server room 18. We also installed a new UPS plus transformer in this unit as well.
- Worked in B/A server room 19 started swapping out servers into another rack mount unit to install another new UPS plus transformer. This is a continuous project.
- Worked up at LHO with Christine to help setup and configure a server for ADVLIGO Carol’s group. This also consisted of setting users workstation to connect to the new server. I also setup a VPN server to grant users from the ADVLIGO team an offsite connection to the Hanford network.
- Worked with Larry in trouble-shooting the backup mail server.
- Worked with our group on moving equipment from one rack too another to swap out an existing UPS with a new UPS that has much more amperage to handle new up coming servers. This is an on going project.
- Working with Dwight and Christine @ LHO on Primavera installations, plus changes in the configuration on the VPN server that I setup in Hanford. Things seem to be working ok for now.

Advanced LIGO and Supporting R&D (Shoemaker)
Advanced LIGO Management
From: Carol Wilkinson <wilkinson@ligo-wa.caltech.edu>

Advanced LIGO Systems
Modeling and Simulation
From: Sanichiro Yoshida <syoshida@selu.edu>
I put together our group's weekly for Hiro.
Modeling and simulation (Sany Yoshida)
- Based on Mark Barton's most updated mathematica model, Richard created a state space matrix in the e2e format. This model simulates the Adv LIGO quad suspension taking the violin dynamics into account. We tested the model by including the state space matrix in our e2e quad sus code. For the position (translational motion normal to the mirror surface) DOF, the resultant power spectrum shows a peak around 420 Hz, as expected.
e2e Weekly meeting
Attendees: Osamu Miyakawa, Richard Williams (SLU undergraduate student) and Sany Yoshida
We discussed the progress on e2e modeling of the Advanced LIGO baseline HAM seismic isolation. The Southeastern team has made an e2e model based on a matlab model provided by the SWG. The computed table top motion seems to be reasonable, but needs to be verified by the SWG. Osamu confirmed that he could still use the simplified HAM seismic isolation model for his e2e Advanced LIGO optics simulation so that the Southeastern team would have some time to verify the HAM seismic isolation model. We also discussed possible Southeastern student's visit to Tama next summer.
Static IFO simulation (Hiro)
Hiro was on vacation.
Modeler : e2e simulation engine and ALFI : e2e front end (Hiro, Bruce, Melody)
(Melody Araya)
ALFI
- Worked on the draft for the Use of User-Defined Primitives in ALFI. Integrated Bruce's changes into the document.
- Installed a standalone version of ALFI 6.6.2 in Hiro's laptop.
CDS Prestabilized Laser
From: Peter King <pking@ligo.caltech.edu>
- In going over the requirements for the laser diode enclosure, I found that the interface document was sadly out of date - it dates from when the laser still had an injection-locked front end. I have been updating the interface and signals, keeping in mind the division between local control by the Beckhoff Automation hardware and EPICS.
- I finally finished laying out the circuit board for a quadrant photodetector. Parts for said board arrived from Digi-Key.
- Benno has started drafting a testing plan. It's in point form at the moment as we are deciding which tests to include (and where).
Seismic Isolation
From: Ken Mason kmason@ligo.mit.edu
BSC Seismic Isolation Assembly and Test
- Both stages are now floating and the locater/locks are installed. We have begun installing the actuators and cabling.
- Balancing of stage 1 has been difficult with over 100 lbs needed in two of the three corners. We believe this is due to tolerance buildup in the spring mounts and shims and are looking at ways to accommodate this amount of trim mass.
Single Stage HAM Procurement and Test
- Bob Taylor has completed the cleaning of the actuator bobbins and shipped them back to PSI. They will be winding the coils next week. Andy has completed the design of the coil wire termination using peek terminal blocks supplied by Accu-Glass. All parts have been ordered and received. They will be cleaned and sent to PSI for integration into the enhanced LIGO actuators. This eliminates the use of epoxy in the actuator.
- To prevent escalating costs from HPD, we have instructed them to "red-line" drawings instead of creating an ECO for each minor change. We will update drawings after completion of the prototype assembly and create an "as-built" drawing package.
Suspensions
From: Norna Robertson <nroberts@ligo.caltech.edu>
- Attended ALUK PAG (Advanced LIGO UK program advisory group) meeting in Glasgow.
- Chaired schedule update review for enhanced LIGO at ExComm telecon on 4th Sept. Mike Zucker presented the current schedule and plans. General summary: timing of end of S5 and post S5 calibration period is pacing item in schedule. Various issues being closely watched (septum delivery date, HAM ISI progress - no longer pacing item, Faraday isolators - installation logistics and manpower, EQ stops - procurement/fab, cleaning and baking organisation - now in hands of Stephanie Foley at MIT, and site assembly space - competing with maintenance needs). Short report being prepared by NAR.
- Checked eddy current damping (ECD) level and associated thermal noise for current beamsplitter triple pendulum design for longitudinal and vertical directions assuming the same ECD units as used in the quad design are applied. Damping is good enough for acquisition mode (damping time ~ 12 secs or less) and thermal noise is less than technical noise requirement at 10 Hz (1/10th of fundamental noise requirement). All good news. Other degrees of freedom to be checked, expected to be OK.
- Got guided tour and demo of ribbon pulling machine, bounce tester and profiler in the lab in Glasgow, all of which will be heading to LASTI later this year.
From: Janeen Romie <janeen@ligo-la.caltech.edu>

From: k mailand kmailand@ligo.caltech.edu
Adv. LIGO
- I have taken apart the suspension in the 056 lab for Mike Gerfin to modify, and set up the test faraday 4 wire style damper test in Phil Willems lab.
- The preliminary assembly of the installation arm tool is in progress, also work on a test setup has started.
From: Chris Echols cechols@ligo.caltech.edu
No report
From: Helena Armandula ahelena@ligo.caltech.edu
Adv. LIGO SUS
- Ears are bonded in LASTI's penultimate mass and ETM optic. The bonds look good and they are curing at this time.
- Bonding of ears on a second penultimate mass will take place sometime in October.
Core Optic
From: GariLynn Billingsley <Billingsley_G@ligo.caltech.edu>
- I attended the SPIE exhibition and was able to look two of our possible polishing pathfinder vendors in the eye and say "you've got our RFP?" The answer in both cases was affirmative, they also indicate that they will be submitting proposals.
- The main purpose of the visit to SPIE was to meet with Ted Mooney from QED. We went over the status of the pathfinder optic at QED. The final conclusion "it will be in spec but it may not be what you really want" For more detail see the QED weekly report at LIGO-C070158-00. This is one of the purposes of the pathfinder, to discover if our specification really covers what we want. QED has presented a possible remedial step. We will discuss this further at the final review, scheduled for October 5th at QED. Rochester NY.
Auxiliary Optics
From: Michael Smith smith@ligo.caltech.edu
STABLE RECYCLING CAVITY
- Mike modeled the diffraction loss due to the clipping of the beam by the beamsplitter and the MMT3 mirror, with and without an elliptical baffle, using ZEMAX. One elliptical baffle is placed in front of the MMT3 mirror to block the portion of the beam that spills over the tilted BS. Two other elliptical baffles are placed in front of each ITM, to block the beam from the arm cavity that spills over the tilted BS from the ITM direction.
- With an input beam size w=2.23 mm and wavefront curvature of 76460 mm at the MMT1 mirror, the cummulative round trip loss without an elliptical baffle is 720 ppm; and 880 ppm with the elliptical baffle. A power point presentation describing the results is found at http://www.ligo.caltech.edu/~smith/G070614-01_stable-recycling-cavity-loss-ZEMAXL.pdf .
Input Optics
From: David tanner@phys.ufl.edu
Rodica Martin and Luke Williams:
- Cleaning, baking and helping on measurements on the e-LIGO Faraday magnet. Measurements of the separation angle of the e-LIGO calcite polarizers. Packed parts and shipped them for vacuum bake for e-LIGO
Muzammil Arain:
- Tested Silicon Carbide in vacuum for baffle material testing process. An e-LIGO size and power beam was incident at SiC. No visible damage or glow was observed. The test lasted three hours. There was some outgassing but pressure stabilized in 20 minutes.
- Antonio and Valera measured the back reflected beam with recycling mirror misaligned. The low-power data shows that the beam has changed since the last known measurements, made in 2003. This could be due to some shift in the position of MMT2 or could be due to some thermal lens in the Faraday isolator. Further investigations are underway.
David Tanner, Guido Mueller, Dave Reitze:
- Made strawaman staffing assignments for the e-LIGO assembly/installaton of Faraday isolators and EOMs, based on Mike Zucker's latest schedule. No one has to be two places at once.
Other R&D
From: Riccardo DeSalvo <desalvo@ligo.caltech.edu>
Arianna:
- I'm working with labview to build a program to find the working point of my system, by doing a scan in amplitude.
- A program for synusoidal excitation scans is already done (by John) and i'll use it to take data by changing the frequency of the input sinusoidal signal. I hope to find the way to do everything as soon as possible.
Maria:
- back to high school; made some manual hysteresis measurements, with interesting results, showing hysteresis for different axcitation amplitudes and pointing out the importance of thermal corrections.
- Writing a report, but will continue showing up in the lab in her free time.
Andrea:
- I'm studying the schematic top view of the arm interferometer, in order to calculate the angles at which we can physically put our scatterometer photodiodes.
- Thanks to the BRDF vs angle curves, I can infer the power scattered at the selected angles and from the responsivity information of the photodiode, I can find the current produced. An I'm going to compare this current with the noise measured.
- Made measurements of signal to noise with light fluence similar to what expected in the beam line. Tomorrow I'll go to talk to Rich about my electronic work, I Found some mistake with the electronics, and I'll perform the measurements without any resistance in parallel to the photodiode.
- Just right now, I'm going to correct the first part of the report, and I'll add the new measurements. Preparing to leave.
Alberto:
- Left from MIT, visiting Caltech, given HAM SAS presentation in Caltech, working on the paper during forthcoming shifts before returning to Italy for graduate school applications.
Zeb: Out for a break, will continue the work on polyhymide resin when Caltech resumes.
Sachin: Back to high school.
Zeb and Sachin:
- Completed a polyhimide resin curing without visible bubbles, must section to inspect interior.
John:
- Waiting for the lab to be rehabilitated.
- Written two reports for the Grlasgow doctoral school.
- Assisting Arianna.
- Measuring mirror losses to verify the Mexican Hat power recycled design.
