LIGO
Hanford
Observatory (LHO) and Interferometer Operations (Raab)
Summary of Activities at LIGO Hanford Observatory (compiled by M. Landry)
- Progress in DC readout is captured in these displacement spectra, comparing RF and DC locking at 3.7W into the modecleaner. The broadband performance of DC readout is better than RF above 150Hz (there is a lump at low f that is worse however). Limited central TCS heating was employed for this measurement.
- Power up is the next major step in eLIGO commissioning. Power budgets in the WFS paths were borderline, so the power on ISCT1 (WFS3 and 4) and ISCT4 (WFS2 and POX) were reduced by a factor of 5, via appropriate splitter placement. The IFO currently likes about 6W, but falls out of lock within a minute with 7W of input power. In the process of reviewing REFL paths, the beam was found to be too large on WFS3, so a realignment (with lens swap and repositioning of table components) of the H1 REFL table was made. Power up locking was restored and further measurements ensued.
- The tip/tilt hardware shutter to protect OMC photodiodes, previously slower than the redundant software shutter, is now reinstalled, recommissioned, and faster than the ~1ms software at 700us.
Astrowatch (A. Mullavey)
- The uptime for H2 over the last week was 52.0%. It was in science mode 16.6% of the time
- The week started with H2 up 60-70% of the time, however high winds around the Hanford area and more computer problems over the last few days has brought this number down
LIGO
Livingston Observatory (LLO) and Interferometer
Operations (Giaime)
General Operations (Rusyl Wooley)
- We received the final drawings from the architect for additional office space in the staging building as well as relocation of the LDAS tape robot. A P.O. was issued to Cangelosi - Ward for the aLIGO facility modifications. We put HAM2 and HAM3 annulus spaces back on their ion pumps and began pump down of the HAM5 and HAM6 annulus space. Mike Fyffe and Carl Adams have been working with Peter King to build us a spare ISS board. David Kinzel is working on a back up power proposal as part of our emergency preparedness plan. Pending a certificate of insurance from the waterproofing contractor, we will be issuing a P.O. number in order to begin Beam Tube Enclosure joint repairs. We have been interviewing SolidWorks drafters this week and have chosen who we want. I am in final negotiations with the recruiter with hopes of having someone on board within the next two weeks.

LIGO
40-Meter Interferometer (Adhikari)
- The Ranger seismometer had a bad connection to the DAQ. This was repaired.
- The performance of MISO Wiener subtraction for removing seismic noise from the Mode Cleaner was evaluated. It seems that this feedforward system would not need to be adaptive. There is no observed degradation in the residual noise spectrum over ~5 hours with a static set of FIR filters.
- The prototype LM34 based BSC temperature sensor was installed on the MC1/MC3 table. We will now start monitoring the trends and also the drumhead frequencies of the MC optics to make a long term absorption sensor. If this seems OK, we will fabricate more of these to install at the sites for the science run; one for each test mass chamber.
Thermal Noise Interferometer (Black)
- A short has developed in the interlock of the phothermal probe laser (800mW NPRO), and after determining that the problem was on the circuit board and not in a more accessible connector or line, Greg contacted the manufacturer and is sending it back to be repaired.
- We met with the TNI advisory board on Wednesday and discussed plans beyond the upcoming doped-optimized coating measurement.

Laboratory Computing (Anderson)
LDAS Software Systems (Maros)
- Progress has been made in two important areas this week. First has been in the area of creating an RPM to ease the installation process of lsync. Although incomplete, substantial progress has been made and an RPM is expected to be made available early next week.
- The second area is with implementing the Version 8 Frame Specification. The core infrastructure has been proven to work. The effort now is in implementing the differences between this version and version 7.
- System testing of LDAS was done using version 1.11.21. Lsync failed. Current speculation is that there is an error in the test script. It is being investigated. Also, 8 of the regression tests failed. This has not yet been investigated.

Advanced LIGO and Supporting R&D (Shoemaker)
Advanced LIGO Management
From Carol Wilkinson
Project Controls
- The project office has created a form for Level II change requests in addition to the Level I form already in use. These forms are used for minor budget and schedule adjustments within a single subsystem. They cannot be used to request contingency or if other subsystems will be impacted.
- Advanced LIGO Change Requests (ACR) in process:
- The ACR for delay in PSL delivery schedule of 200 W lasers by 6 months will be processed and implemented in December. Uses schedule float and does not impact project schedule for installed units. Spares will be delivered after the install date.
- An ACR to add HEPI units to the output readout HAMs per request by the ISC subsystem is in preparation, pending a RODA that HEPI is the isolation of choice. Budget in ISC for seismic isolation of these chambers will be transferred from ISC to SEI HEPI. No significant change in budget or schedule milestones anticipated.
- ACR to consolidate the clean and bake activities in the assembly staging activity in Facility Mods. and Prep is in preparation, with expected implementation in November. Labor in the individual subsystems will be collected and moved to FMP. Expectation that more labor hours will be needed.
- ACR to increase staff at the various sites to help technical leads with procurement and documentation preparation is being prepared. The intention is to bring some site assembly folks on early and to hire temporary drafters at each of the four sites. Project contingency will be used where appropriate. Some of the drafters will also help with development activities paid from operations accounts.
- An ACR to add optical tables to the SUS assembly tooling has been prepared and will be circulated to the subsystems leads for discussion and comment at the next Monday meeting. Tables at an estimated cost of $80K were left out of both FMP and SUS budgets.
Staffing
- Ads/job descriptions are out for draftspersons at LLO, CIT, and MIT to help with AOS, SUS, and SEI drawings. These are temporary contractors. LLO has identified a candidate and will proceed with negotiations.
- Ads are also out for an optical scientist and a technician. Both contract and term CIT employee options are being explored.

Facilities Modifications and Preparations
From: John Worden <worden_j@ligo-wa.caltech.edu>
- LHO - Bids for the Staging Building Modifications were opened on Tuesday. Three bids were presented and the low bid was from Apollo Sheet Metal, Inc at a value that which was acceptable. Apollo is very familiar with our site as they did all the mechanical work on our original buildings. The also provided craft labor for the PSI Vacuum work.
- LLO - The Warehouse Renovation contract has been approved by the NSF.
Seismic Isolation
From: Ken Mason kmason@ligo.mit.edu
SEI Project Activities
- Brian O'Reilly and Joe Hanson visited PSI to witness the winding of the actuator bobbins. They are inspecting the quality of the bobbins with the new polyimide coating and talking to them about their testing procedures.
- The STS2 Interface, DAC Interface, and 8 channel Valve Driver are ready for order. The schematics, PCB, bill of materials, etc. are in a file repository, waiting for my go-ahead for the order placement. The Pier Interface has been re-designed (again). This time, to incorporate the Inductive Position Sensor inputs and their passthrough electronics. It is also in the file repository, ready for order, but I want to take one last look at it next week before I'm confident about its suitability. This now leaves the Pump Servo to be designed, and a small Anti Alias Interface board to be drawn up, and the electronics will be ready for order.

Suspensions
From Janeen Romie and Norna Robertson
(romie_j@ligo-la.caltech.edu, nroberts@ligo.caltech.edu)
Operations Work
HAM Suspensions for Advanced & Enhanced LIGO:
- Documentation completed for large and small triple PDR (thanks to various SUS team members) and posted to wiki site.
- Worked on budget needed to complete R&D work for HAM suspensions.
- Nickel plating update - Test small blades came out looking mottled on the first attempt. For the large blades, they are going to try to scrub the blade surfaces before they go through the cleaning process and see if it helps. The vendor suspects that there might have been some build-up on the surface of the blades that the cleaning process didn't remove.
BSC Suspensions for Advanced LIGO:
- Draft of BOSEM report summarizing the resolution of outstanding items from the final design review was circulated for comment.
- Alastair Heptonstall is back at LASTI working on fibre pulling machine and associated hardware and on welding tests.
Project-Funded Activities
- Monthly variance report completed.
- Prepared list of key dates in the quad schedule leading to first monolithic installation.
Core Optics
From: GariLynn Billingsley <Billingsley_G@ligo.caltech.edu>
- Polishing specifications are in final review. I hope to go out with an RFP next week.
Auxiliary Optics
From: Michael Smith <smith@ligo.caltech.edu>
ADLIGO
Work Under Project Budget
- OPTICAL LAYOUT: Luke is working on the optical layout for the folded IFO.
Work Under Operations Budget
TCS:
- Muzammil investigated several IR cameras for use in calibrating the TCS system. TCS needs to purchase an IR camera to have on hand at the LLO site. This item is not in the TCS budget.
ETM TELESCOPE SUS:
- Ken has completed the design for the ETM Telescope suspension test prototype. Some of the parts have been fabricated and the remaining parts for the assembly are expected to be fabricated by 11/21/08.
- Mike is trying to design a broadband achromatic refractive ETM Telescope that works with 532 and 1064 nm wavelength. An off-axis parabolic mirror reflective design similar to the initial LIGO PO telescopes may be the simplest solution.
- Aidan and Phil will determine the thermal defocus stability requirements of the telescope for the ETM Hartmann beam. Mike is looking into transmitting the reflection from the ETM AR surface through the ETM telescope as a reference surface for calibrating the ETM Hartmann beam.
OPT LEV:
- Eric B. analyzed the servo system requirements for damping the IFO using the optical lever beams to read the orientation of the penultimate mass. The voltage noise requirement of the optlev QPD signal appears to be only one order of magnitude lower than the currently obtainable voltage noise of the LHO QPDs. It should be possible to redesign the QPD electronic circuit by biasing the QPD (rather than operating in photovoltaic mode) and reduce the voltage noise by at least a factor 10. However, at the moment it does not appear possible to place an optical lever beam on the penultimate mass through existing viewports without using additional steering mirrors within the BSC chambers.
MEZZANINE LAB:
- The accelerometers for the SUS mezzanine Lab have arrived. Ken ordered tools thru tech-mart. He is creating signs, lighting, and is moving equipment to prepare the mezzanine Lab.
Input Optics
From: Rodica Martin <rmartin@phys.ufl.edu>
ELIGO Commissioning (LLO)
- PSL power measurements and ISS checkout. (Antonio)
Preparation for high power in the IFO: (Kate)
- Found best TCS settings for input powers of 6, 7, and 8 W.
- Improved RBS servo with new sensing and control matrices.
- Measured power budget of POX path in preparation for high power.
- Measured ASC sensing matrices at 7W; implemented new control matrices.
- Set AS_I phases.
- Re-phased WFS.
- Fixed pointing into MC.
- Installed Delrin riser blocks on REFL1 PD to provide RF insulation.
ALIGO Design
- We have developed a solution for the coupled cavity Eigen-values in the modal model picture. We think that this modal model will help in evaluating the performance of the Advanced LIGO cavities. A technical note about this would soon be posted. (Muzammil)
- We have tested a low cost (less than 5,000 US$, Fluke Ti25) IR thermal imaging camera and it looks like a very nice tool to have. It would help a great deal is checking various windows and components for thermal problems. (Muzammil)
- Measurement analysis of thermal lensing in AdvLIGO modulators. (Volker)
- Work on parallel modulation MZ experiment. (Volker)
- Working on folded aligo layout. (Luke)
- Modifying the drawings according to recommendations from SUS for asymmetrical wedge. (Luke)
- Tweaking specifications for AdvLIGO IO substrates. (Rodica)
- Writing a technical document on light scattering in the Input Mode Cleaner. Reading about feedback loops and control electronics in AdvLIGO. (Rodica)
ALIGO Acquisition
- Adjustments
on the bid package for mirror polishing so it includes instructions and notes to clarify and expedite the acquisition process. We expect RFQ for the first batch of substrates go out in about a week. (Rodica)
Prestabilized
Laser
From: Peter King <pking@ligo.caltech.edu>
Operations
- Nothing significant to report.
Project
- The spare ISS at LLO has been modified to be the same as the unit actually operating on the table. There was some initial confusion because the board revision because the spare unit is a different board revision than the unit on the table. Documentation was generated to bring the previous revision board to the current version of the servo.

- Rebuilt the OMC/ISI front end code against the latest CDS software versions.
- Loaded new libtestpoint.so software, as modified last month at LHO. Since the update, the ISI multiple, long awgstream sessions have been running through to completion (was a problem before the update).
AdvLigo DAQ:
- In process of laying out the details for the site test systems. To be documented in a brief tech note, which should be ready for circulation in a week or so.
- Also preparing a document on the ADC/DAC timing and diagnostics details.
Timing:
- Received the revB DuoTone interface boards, tested the boards and related test document. Received revB Master/Fanouts, test in progress. This provides most of the hardware needed for the 40m installation. Converging on iterating timing design for the 40m installation. Converging on the "Quick-start Guides" to accompany the hardware.
