Vent Work Plan for the Week:
HAM5 OFI Update
Reinstall doors on HAM5, and HAM6 North
Move HAM4 cleanroom for vacuum work
Install NAG pump on output tube
Replace Ion Pump with valve on HAM4
Viewport install on HAM5
Replace HAM6 feedthrough
Closeout work in BSC1, 2, & 3
- All dog clamps holding the OFI spacer
were re-torqued, due to finding one dog clamp loose.
- AOSEMs were set on brackets and
positioned to be close to center (per MEDM screen), all
fastening components were tighten, set screws and adjustment
collar screw, to hold them in place.
- Transfer functions look great:
Suspension looks free, resonances are in the same place as
they were before, DC gain looks the same and Qs of resonances
are only slightly reduced, no danger of over-damping.
ITMX/Y ESD Feedthru Retrofit
- Both feedthroughs were removed and replaced while all door
covers were on. We removed the old style feedthroughs and
installed the new type (Accuglass PN100520) on BSC1 and BSC3
(flange F2, subflange 3 for both BSCs).
Corner station closeout progress
- ITMy had its “pizza crust” FirstContact painted on the
perimeter of the FC spray sheet that was applied last week.

pinch point in the Top Mass. The cable was moved out of the
pinch point and the short was alleviated.
- BSC1, 2, 3 SUS ESD and cable ground work finished
Electronics, Control and Data Systems Operations
F. Clara, C. Perez, M. Pirello, Ed Merilh, G. Moreno
- Finished ESD feed through work on the ITM chambers. Had some problems Hi-Potting the cables as one connection in chambers kept showing a short. This was overcome by repositioning the center pin on the connector and putting everything back together.
- Assisted with the close out BSC chambers by testing grounds on suspensions. Have a couple of cables on the exterior that needed some work to isolate the shell from pin 13s shield. All chambers have been completed. br>

Detector Engineering weekly summary for Stuart Aston, Matt Heintze, Adam Mullavey & Arnaud Pele
The Post O2 Vent work is winding down for the LVEA. At this point, only the HAM 5 & 6 work is ongoing, specifically finishing off the OFI actuation installation and checking the squeezer alignment. BSC1 is open and installation of the four elliptical baffles (ITMs and BSs) and their associated alignments was started this week and will go into next week.
HAM4 was closed this week. Work in HAM 4 accomplished this week includes ground loop hunting with Carl A, B&K measurements of the baffles and SR2 TFs look clear after First Contact removal, see alog 37047.
HAM5 work this week included ZM2 HTTS OSEM centering and taking Phase 3a (in-air) undamped TFs - show no rubbing, and appear consistent with those taken when unit was installed back in May 2016, also verify no issues with the new dedicated electronics chain, see alog 37095.
Also, HAM5 OFI Actuation installation of actuator parts. The UPS-delayed shipment finally arrived yesterday, three weeks after it was sent. See alog 37066.
HAM5 B&K measurements have been completed for new baffles and suspension structures, see alog 37078.
HAM6 ZM1 HTTS Phase 3a (in-air) undamped first TFs were taken and show no rubbing, or obvious mechanical issues, see algo 37062.
Setting-up B&K test of new Vibration Absorbers uncovered an assembly issue, which has now been resolved. 3 units of 13 tested, 2 units of which are to be installed imminently in BSC2 on the TCS Mirror Assemblies. Some will be sent to LHO, after the holidays so as to avoid shipping snafus.

Facilities Weekly Completed FRS report:
Facilities Weekly Accomplishments / Enhancements:
- Facilities is providing 2-a-day cleaning for 4 open chambers (HAM 3, 4, 5, 6) while also completing our routine technical cleaning and FRS work.
- In an effort to reduce noise and vibration in the Corner Building LVEA, the condensing unit located inside the building on top of chiller/diode room adjacent to the LVEA has been relocated to outside of building per work permit 4373. This work was completed by LLO staff saving hundreds of dollars and reducing down time.
- 4 team members from Facilities along with 2 other staff members from the Operator’s group completed the required hazardous material shipping certification course this week. The certification is needed in order to package and ship as well as receive hazardous material.
- Facilities continues routine PMs on all HVAC equipment including Corner Building, Staging /SEC Building, VPW, Mid Stations, and End Stations.
- Facilities continues to complete all called in requests timely with in house staff saving time and money.
Education and Outreach
- Conducted one public tour. Facilitated by William Katzman.
- Conducted 3 field trips. Facilitated by Kathy Holt, William Katzman & Tien Huynh-Dinh.
- Conducted 4 tours in conjunction with the American Geophysical Union’s conference. Facilitated by Keith Thorne, Kathy Holt, William Katzman, Tien Huynh-Dinh, Richard Oram with input and assistance from other scientists.
- Attended teacher professional development collaboration meeting in order to better coordinate with offerings.
- Prepared for upcoming Science Saturday.
- Updated website with news story.
Mechanics, Optics & Vacuum
- Returned to finish work on testing BRDs for potential use with beamsplitter. Compared BRD Qs in vacuum (taken using Thomas tank) to those in air. They were essentially unchanged for bounce mode, slightly higher for roll mode. Results and final conclusions in T1700176-v6.
we continue testing the LHO cavity. We improved the mode matching for both wavelengths. We Performed higher order mode separation, escape efficiency and non-linear gain measurements, and are currently processing the data. Preliminary tests results are being compiled in DCC document E1700420.
- Followed up on order for SiC beam dump kit
- Updated Shroud assembly documentation per ECR
- Worked on Temp Fix for BS wire baffle
- Followed up on order for LANS 75mm HOLDER ASSY.
- Identified suitable VP Guard for AWC VP assembly
- Attended unconscious bias workshop
- Located vendors with precision abrasive blasting capabilities and requested samples of mill finished 304 SSTL bead blasted to 70 RMS.
- Detail SRM AR MCB2 ghost beam baffle (WIP)
Control and Data Systems
- New PCIe switch arrived at LLO for the test stand. This completes the set necessary to test the full configuration ie 2 arms and corner of the long range PCIe network with the latest hardware and software. Testing will continue until the bulk of the equipment arrives in February for installation into site controls at both LLO and LHO.
- Spent a few hours trying to reproduce the timing glitch errors reported by KAGRA in their system. They have a different hardware setup for the link between computers and the I/O chassis ie PCIe Gen2 cards with a PCIe Gen1 I/O chassis backplane (ours is Gen 1 throughout). I was unable to communicate with our I/O chassis at all when I installed this configuration here, so will need to go back to them for more info.
- Proper gender pig tail fibers arrived for our new prototype I/O chassis. Testing has now started using a long (75m) multi-core trunk fiber between computer and I/O chassis. Everything is working fine thus far. Now looking into how we might improve the internal wiring while we wait for final back panels to arrive (next week).
NDS2 (client, server, and server infrastructure)
- Identified an error in the nds client iterate implementation and fixing.
