I updated the filter bank on the quad test stand again to capture a few corrections that had been made to LLO's /opt/rtcds/tst/x2/chans/X2SUSQTS.txt since it was generated from LLO's /cvs/cds/llo/chans/L1QTS.txt in the recent upgrade. (A few filters had names that did not match their functions.) I took the LLO X2SUSQTS.txt file, changed all the instances of QTS_ back to Q1_ and installed it at LHO /cvs/cds/llo/chans/L1QTS.txt. The L1QTS.txt file that was in place for a day is at LHO /cvs/cds/llo/chans/L1QTS_LLO_20101117.txt. I also went through the MEDM screens and made sure that the correct filters were enabled (some filters are in different positions relative to the old LASTI set).
It is using the 4K OMC line.
Began pumping YBM. Dewpoint of "blowdown" air comming from YBM after decoupling purge plumbing measured -16C (John elected to not repeat exercise previously done with X-end ((see recent entries))but rather to just pumpdown)*Combined Diagonal with XBM by opening GV4*Vented combined volumes*Removed all but (4) loosened bolts from BSC7 east door. Engine hoist connected to door and taking some of the load.
Main activities for today:
I updated the filters on the quad test stand ( /cvs/cds/llo/chans/L1QTS.txt ) with the set from the file of the same name and location at LLO. (Due to the recent upgrade at LLO, the working set there is actually /opt/rtcds/tst/x2/chans/X2SUSQTS.txt which is functionally identical but has been conformed to a new naming convention that has not yet been brought in at LHO.) The old filters are archived at cvs/cds/llo/chans/L1QTS_LHO_20101117.txt . The new filters correspond to the electronics at the sites, which is different from that at LASTI. Derek Bridges has summarized the filters as follows: Input filters (both chains, all OSEMs): 1. "10:0.4" - zero at 10 Hz, pole at 0.4 Hz - zpk([10],[0.4],1,"n") Output filters (both chains, all OSEMs): 1. "1:31" - zero at 1 Hz, pole at 31 Hz - zpk([1],[31],1,"n") DOF filters: M0-X: 1. "0:15,15" - zpk([0],[15;15],1,"n") [the rest are similar with 15 replaced by 20 or 25] 2. "0.43Boost" - zpk([0.428;0.428],[0.1427+i*0.4035;0.1427-i*0.4035],1,"n") M0-Y: 1. "0:15,15" M0-Z: 1. "0:20,20" M0-Yaw: 1. "0:20,20" M0-Pitch: 1. "0:25,25" 2. "0.54Boost" - zpk([0.324+i*0.432;0.324-i*0.432],[0.108+i*0.5291;0.108-i*0.5291],1,"n") 3. "1.13Boost" - zpk([0.78+i*1.04;0.78-i*1.04],[0.26+i*1.2737;0.26-i*1.2737],1,"n") M0-Roll: 1. "0:20,20" R0-X: 1. "0:15,15" 2. "0.43Boost" - zpk([0.428;0.428],[0.1427+i*0.4035;0.1427-i*0.4035],1,"n") R0-Y: 1. "0:20,20" R0-Z: 1. "0:20,20" R0-Yaw: 1. "0:20,20" R0-Pitch: 1. "0:25,25" R0-Roll: 1. "0:20,20" Both chains, all DOFs: 10. "Ellip50"
It started early and fast. Trucks arrived at 0700 and most of the heavy work done by 0745. Slab for new H2 Electronics room done today.
(Corey, Jim) Today, the unit#3 ISI was locked, and we began disassembly. Weights were removed from the table top. Masses were removed off the Outer Walls. Some walls have been pulled off. Some cabling has been coiled up.
Kyle-installed BSC8 south door
With the removal of all H2 electronics and cable trays, moved the kill button from the H2 PSL area to the Squeezer setup area. Tested all five of the kill buttons to ensure they remove power from the five locations lasers can be plugged into. They are TCS X,Y, Diode Room, 4kPSL, Squeezer set up area. Everything worked as designed. Will have to repeat this process when I install a power outlet by Ham4 for the squeezer install.
Card access to the LVEA via the High Bay/Large Equipment Access door should (in theory) be restored. See Richard if you continue to have issues with that particular door.
Rolf, Alex, Keith, Jim, Dave, Richard, Cyrus The aligo CDS control room systems and the H2 front end systems were installed during the week of Nov 9th - Nov 12th. Details can be viewed on the network drawing D1002255 (last page) Prior to this week I had installed a new rack in the MSR to support the aligo CDS control room systems. This rack has a network switch (for the OPS LAN, supports control room and (L)VEA workstations), a NAT router to the GC LAN, a new CDS wiki machine, a combined NFS/DNS file server and an administration machine. During this week we installed to routers between the OPS LAN and the H2 FRONTEND LAN, these run the EPICS gateway, the GDS gateway and the router. We cloned the DTS boot server and created a new H2 boot server (called h2boot). We moved most of the front end machines off the DTS system and put them onto the H2 system. These machines are all located in the Computer Users Room, next to the DTS. We reracked the H2 DAQ system into its permanent rack, but it is temporarily located in the CUR for testing, it will permanently reside in the MSR. We are running many H2 front end systems on these machines, acquiring the data on the H2 DAQ. We installed three new workstations on the OPS lan and tested the major client code (dataviewer, dtt, medm) across the networks.
Took over operator duties from Jonathan around 1:00. Finished removal of all components from BSC8 (Cheryl, Jodi, Mitch, Jim, Patrick) Richard, Cyrus diagnosing card reader access for the LVEA large equipment man door. Gerardo to mid Y to move pallets into the lab area. Assembly of squeezer experiment continues.

(Cheryl, Patrick, Mitchell, Jim, Jodi, Mike) Status in BSC8 as of Friday 4:30pm: Once the BSC door was removed, the team locked down ITMY and FMY, removed OSEMs, and began extracting auxiliary components such as black glass beam dumps and associated (unwieldy) aluminum structures. Several of the latter had galled bolts which had to be snapped to remove. Hardware for the removal of optics and LOS structures was staged in-chamber. We expect to complete this work today Mon 15th.
8:15 - Electrician out in the LVEA Ski, Richard, Jodi, and others moving a clean room near the PSL Patrick to End X to replace dust monitor cabling 11:31 – error entering LVEA - unnamed card (#508) 12:00 - Gerardo arrives in 1 ton truck with delivery ~12:25 – card reader error – undeclared card into Large Equipment Main Door ~12:33 – card reader error – undeclared card into Large Equipment Main Door – 3 times within a 2-minute span 12:45 - Patrick returns from End X ~1:00 - beginning of staging and removal of BSC8 door and removal of optics. This work continues at the end of the day.
X-end air <-54C when measured with purge line decoupled and 1psig air blowing out from VE into the room, i.e. OK now -> began pumping X-end. Pumped YBM+Y1 with YBM MTP for ~2 1/2 hours to partially remove ~3 weeks of accumulated H2 from CP3, Y1 and CP1 -> Vented YBM, removed all but (4) bolts from BSC8 south door.
R. McCarthy, C. Reed, F. Clara, Zack & Rodney (manpower) Finish removal of cable trays around H2. Not all cable trays around BSC8, BSC4, BSC1, BSC2, and BSC7 were removed, since H1 / access system cables are still running on some cable trays. Moved H2 PSL racks away from the PSL table.
