Subsystem Level

Carol Wilkinson:

• No report this week.

Hanford Site

Mike Landry:

• The first of the two BSCs of the single arm was sealed up for pump down - the dome and door were restored to BSC8 (which houses ITMY/FMY). A series of closeout operations were performed, including removal, repainting and removal of First Contact on ITM high-reflectivity surface, arm-cavity baffle hardware removal, photographs and inspections of the entire chamber, and the placing of witness plates for contamination assessment.
• Progress at BSC6 includes adjustments in height (1mm) and lateral position (2-3mm) of the ETMY reaction chain. The IAS crew then made alignment checks of position, pitch, yaw and ETM/RM gap. In the EY optics lab the TMS was split into SUS cube and ISC table/telescope parts, for independent transport to the VEA and attachment to the ISI next week.
• The H1 output mode cleaner tube was extracted and removed from the LVEA, as was the eLIGO HAM6 septum plate. Ion pumps removed from the H1 MC tube were set on the H2 MC tubes. The HAM9 temporary septum was installed.
• Drywall installation was completed at the H1 PSL enclosure and the addition of insulation is underway.
• External SEI buildups are being made at HAMs 11, 12 and 3. We have to sort a problem in that temporary H2 HEPI plumbing lines interfere with the H1 output mode cleaner tubes; these pipes have to move.

Livingston Site

Brian O’Reilly:

• We removed the isolation stack from BSC3 on Tuesday. A couple of minor issues were identified with the rigging, that will be addressed before we do the next stack (BSC2). We are ordering some new rigging to allow us to keep the clean room level when we move it, and we are getting some new scaffolding to make it easier for people who are working at the top of the BSC. We expect to get to BSC2 in the middle of next week.
• We received the I-beams that will be used for storing the large vacuum ion pumps. Work can now proceed on removing them from the vacuum system.
• The scrap metal container was delivered Thursday.
• Work on the PSL acoustic enclosure is proceeding well. There are some hold ups due to material delivery and the inclement weather. After some trial and error we believe we have a good system in place for hanging the floating outer wall. The construction is being inspected at each step to ensure compliance with design.
• We had a group of visitors in this week to work on the aLIGO DAQ. This included giving a tutorial on the system to some locals. Preparations are underway to test a rack at the X-end station. Currently the rack is in the electronic's high bay awaiting some remaining fiber connections.
• Both end station labs are now empty. Refurbishment will begin next week.

Advanced LIGO Systems

From: Calum Torrie ctorrie@ligo.caltech.ed

• Cables: 247 in-vacuum (priority) cables will be winging there way to LLO and LHO tonight. This is thanks to the effort primarily of Kate and Daphen with massive help from Sam, Chubb, Nicki, Chris and a wee bit of help from me. Thanks also to George and Erik.
• Cable Station: Following closely behind them will be a dedicated "cabling station" for each site. This will include already cleaned and baked spare fasteners, heli-coil's and clamps, specialty tools like band-it-clamp tool, custom snips, hel-coil insertion tool, tapping stand as well as go no-go gages and STI taps.
• Layouts: Layout effort is progressing well. We now have laser beam (or are working on adding laser beam) to top level LHAM2, LHAM3, LHAM4 and LHAM5.
• FMP Tooling: Working on preparing the last batch of FMP tooling for delivery essentially balance of HAM tooling to LHO and balance of BSC tooling to LLO.
• RODA's:
  • Working with TCS, SUS and SLC amoung others to get RODA out to freeze LHAM4 and LHAM5 layouts.
  • Working with TMS and ISC to freeze payload for TMS telescope and top mass.

Modeling and Simulation

From: Hiroaki Yamamoto hiro@ligo.caltech.ed

Static IFO Smulation:

• Operation activity : Jan, Eric, Bill and I had a meeting discussing about the optical in Filter Cavity to discuss about the realistic estimation based on existing data and simulation results. I explained how to use the simulation and generated loss functions and higher order mode content in the cavity due to aberration

e2e:

• Not my work activity : A mail circulated in Virgo says that our time domain simulation tool e2e executable code is installed on Virgo computer. The mail explained how to setup the environment variables to use e2e, amazingly correct.
• Two visitors from Virgo will come to Caltech for a week in the middle of March to learn more about the nuts and bolts of e2e.

KAGR, aka LCGT:

• Operation activity : I am at ICRR, Japan, to help the COC group of KAGRA for the design of optics specification, from January 31st to February 21st. There is a f2f meeting going on from Feb.2nd to 4th.
• I summarize the meeting about next generation LIGO strawman held at Caltech on January 9 to 11.

Suspension

From Janeen Romie and Norna Robertson (romie_j@ligo-la.caltech.edu, nroberts@ligo.caltech.edu)

Reporting on the work of the SUS team: Carl Adams, Anna Aitken, Anamaria Effler, Stuart Aston, Jeff Bartlett, Mark Barton, Betsy Bland, Derek Bridges, Virginia Brocato, Doug Cook, Jay Copti, Phillip Croxton, David Feldbaum, Jeff Garcia, Jesse Garner, Robert Giglio, Kate Gushwa, Jay Heefner, Matt Heintze, Jeff Kissel, Ed Merrill, Mike Meyer, Ralph Moffatt, Gerardo Moreno, Bobby Moore, Andres Ramirez, Janeen Romie, Norna Robertson, Travis Sadecki, Danny Sellers, Gary Traylor, Gene Winton.

LHO:

• Jeff B. adjusted the ETM Quad-3 cabling to remove the stiffness introduced by the lacing of the cables. The Quad will be undergoing additional testing after Suspension testing for the one arm test is finished.
• They have received all of the HAM Triples blades from LLO. The blades have been inventoried and paired per T0900559, and are stored in the desiccant cabinet.
• The assembly of the HLTS Upper Mass has stopped waiting for the assembly tooling to arrive from LLO. While waiting, they have built and installed the Rotational Adjusters and Top Blades in the structure.
• The building up of the Magnet/Flag Assemblies is also under way.            

• BSC8 Install: More work on chamber closeout tasks, including setting OSEMs and EQ stops for final times.  Worked with Lisa on pulling ACB back to facilitate this work.  Reapplied FirstContact to ITMy-HR and ERM-AR for final cleaning.  Removed ERM-AR FC today and observed particulate still.  Closed the ring heater.  Paused for dome replacement scheduled for Thur, before pulling ITMy-HR FC.
• BSC6 Install: Worked on more DOF tuning of the reaction chain, focusing on side-shift, height, and pitch this week.  Waiting for IAS to tell them more about the X,Y position of structure on the ISI table and the gap dimension of the chains at the test mass.  The measurements could tell them what they need to translate the QUAD structure and/or the chains.  The TMS crew is waiting to bring the TMS into the cleanroom and mate to the cartridge.  They need to get the 6 DOF adjustments of the QUAD, and some initial BOSEM health checks, out of the way before they connect to the ISI blocking much of our adjustment access.  Spent some time talking through the TMS transport choreography with the team.  Also worked on clearing a path through the high bays for them (thanks Apollo for the help there).

From Mark:

• Mark did some explorations with the asymmetrical HSTS model to see how accurately they need to position the prisms on the optic. A 0.1 mm position error gives 8 mrad of pitch at the optic and if this is to be corrected with trim mass at the IM, the IM needs to sit at an angle of about 3 mrad due to the large pitch compliance of the bottom wires (in turn due to the narrow front-back spacing). So they should definitely shoot for 0.1 mm precision, which is probably the best achievable with the existing jig augmented by a travelling microscope.
• While working with the asymmetrical model, Mark investigated a discrepancy between pitch angles estimated from the transfer function at DC and from the equilibrium position found from minimizing the potential. The code had a bug, being corrected.
• He translated Jeff K's latest Matlab parameter set for the production HLTS into Mathematica and used it to generate data for buoyancy correction estimates which will be added to T1100616.

LLO:

HLTS/HSTS Production

• MC2 (HSTS) blades are currently undergoing creep bake.
• PR2 (HSTS) now being reassembled after creep bake.
• Disassembled MC1 (HSTS) in preparation for creep baking.
• All PFA/PTFE fixture parts are cleaned and baked.  Some metal fixture parts were modified and were recleaned and rebaked.
• Testing out prism fixtures and magnet fixtures.  So far, they have 1 HLTS sapphire prism glued on a metal dummy mass and 4 magnet/dumbbell assemblies.  Danny and Betsy have given suggestions for optimizing the prism fixtures.
• Assembled new HLTS bridge earthquake stops.  These will be installed on PR3 on Thursday, to be followed by the assembly and installation of the optic protection assemblies (catch pans, face shields) for form, fit & function tests.
• Ralph is almost finished with incorporating Virginia's helpful write-up of the sequencing of overall steps. He is also documenting the locations of the BOSEMs on every suspension, in light of the “sign mystery” issue, resolved as below.
• Checking of angled clamps ongoing.

Testing:

• Solved the PR3 "sign mystery" with Joe B. and Stuart.  The problem was a sign flip due to the fact that the side BOSEM on PR3 is actually on the opposite side from originally noted, which comes with a magnet flip as well. It is positioned as such due to the tight real estate constraints in the HAM2 chamber.

• Updated/Added to Ideal QUAD Testing Order.

Core Optics

From: GariLynn Billingsley Billingsley_G@ligo.caltech.edu

From: Patrick Murphy:

• Completed generating documents for DCC and updated Mass in grams of ERM's at CIT.
• Updated Nebula Document.
• Received Scratch and Dig Stds Modifying procedure E1100768 V4.
• Inventory IO optics at CIT will forward to Rodica for clarification and verification of Physical Inventory.

• Attended COC optics meeting Tuesday
• Verify consumables and quantities in CIT cleanrooms for LIGO.
• Shipped FTIR Samples to JPL for analysis.
• Assisted GariLynn with Optics handling and testing remote piezo controls for alignments on Zygo.
• Completed procurement for mount and optics handling modifications.
• Completed sketch for modifications and sourced to Machine Shop with hardware.
• Procured tripod for SUS group.
• Supporting demolition in adjacent labs to limit impact on our labs.
• Reviewed all COC upgrades to Cleaning methods and materials generated by Margot recently.
• Arranged to re-establish permissions lost and cancelled due to short term contract balance.

From Hiro Yamamoto:

• The effect of the LMA coating on the ETM05 substrate was analyzed using the phasemap measurement done by Gari.
• When the map is used for ITM, the diffractive loss is ~5ppm and the higher order mode in the cavity is ~22ppm and very good.
• When it is used for ETM, by doubling the phase map values (about twice thick on ETM than ITM due to the difference of coating), the loss is ~22ppm  and the higher order mode content is ~260ppm. The loss is around four times of that for ITM, which can be easily understood, loss ~ rms^2. The higher order mode content is larger than four times of 22mm. This is probably because the nominal curvature of ETM, 2245m, is larger than that of ITM, 1934m, i.e., ETM is flatter than ITM, and the same bump on ETM induces more disturbance than on ITM.
• This needs to be taken into account for the final decision about the ETM coating.

From: Margot Phelps:

• Compiled Total Integrated Scatter data and Transmission data for the following Input Optics: PRM01 PRM02 SR203 SR204 SRM05 SRM08.
• It is now all on the dcc: TIS data, E1200101. Transmission data, E1200100.
• Will finish all the absorption data for the above optics later today, and be ready to take absorption scans on the beam splitters that are due to arrive tomorrow.

• Sending C3 crashmat covers, lens tissue, spectroscopic methanol/acetone/isopropanol to sites. Testing a new first contact brush today, will order them in bulk as soon as I get a quote from Gordon brush. Received lenscaps from Kurt and tested the recommended cleaning procedure for these.
• Corresponded with Sys, IO and ISC to come up with an acceptable optics mount design to hold all sizes and widths of ground glass optics in an airbake oven.

From Liyuan Zhang:

• Set up absorption measurement at RTS for IO mirrors, 6 IO mirrors are being scanned by Margot, and they should be done by end of the week. One BS is coming from CSIRO, we will go though the absorption, transmission and TIS for it next week.
• Finished transmission data treatment of recently measured IO mirrors, all of them are within spec expect for SR2-04. The average T of SR2-04 is ~18 ppm, slightly higher than the spec of <15 ppm. Although it's not significant, Rodica is going to contact the vendor and we'll check SR2-01 which was coated in the same run.

From GariLynn Billingsley:

• We have received ETM05 from LMA, preliminary analysis of the coating uniformity as well as data maps can be found at LIGO-E1200093.
• We have all elements in place to implement change order 3 with CSIRO.
• We are scheduled to receive 2 BS and 1 CP by February 3.
