SUS WD were connected to BSC-ITMX model.
The re-assembly of the Test Stand cleanroom was started at Y End and continued for most of the day. Mark Layne went into BSC3 to re-install the two ICC Dust Barriers (slots off-set and covered with taped on foil) between BSC2 and BSC3. This activity was completed by 10:45 am. After the cleaning crew completed their work this morning, Bubba and Mark L. worked on the BSC9 viewports. The two viewports on the door were attached (FC on both sides) but not torqued. There was some confusion associated with the illuminator and video camera viewports: the serial numbers on the documentation did not match up with the viewports on hand. Bubba consulted with Keita and then we unsuccessfully tried to track down (H2 PSL enclosure x 3 calls with no answer, VPW, desk) Joe D. to clarify the issue. If Keita can't find Joe in the PSL enclosure later today, we will talk to Joe in the morning.
Richard requested a new CDS subsystem for the safety controls system. It is called "saf", I have added it to the userapps SVN repo with the usual directory structure.
We should add SAF as a subsystem to the ALOG.
Friday was a busy day!
--- PSL ISS Cable Install - Jim, Mitchel
They got the cables installed in the flange with the worst access.
--- PSL PMC recovery - Filiberto, Stefan, Sheila
Replaced PMC electronics and brought the PMC back to stable locking.
--- IMC alignment - Peter, Justin, Cheryl
Input beam from the PSL was aligned to the IMC irises. I aligned the IMC and it is flashing.
-----------------------------------
On Monday, there is still a fair amount of alignment to do in HAM2 before the PSL ISS can be installed.
1) IMC alignment check - check to see that the PSL beam is still well aligned, and flashing is good
2) Align through FI - requires aligning the beam to PR2 in HAM3
3) Reroute MC REFL as IMC TRANS
When these alignments have been completed, the PSL ISS Assembly can be installed in HAM2
-----------------------------------
IO install work to do latter in the week:
- remove, rework, and replace the PR2 scraper baffle
Had to pull these down to get access to the BSC3 North side actuators. Main ground wire also disconnected. Completely SEI subsystem fault for not carving out enough space to actually work around the HEPIs. Baskets are on the floor nearby with hardware. These really should remain out of the way until HEPI is more completed.
Completed the four Horizontal actuators attachment today. Plenty pain but had worse. Based on the Dial Indicators I may have knocked us out of the Yaw Spec. Jason logged 35urads CCW and I measure 111CW putting us at 76urads CW. This is averaging the four transversely oriented DIs and a few more or less here and there and we could be ok or we could be worse. So, best to just let IAS look and see. If it remains this smallish amount, SEI can likely crank it around with the HEPI DSCW Springs leaving the Actuators attached. Translational moves are insignificant and level shift only improve on the level--gotta get lucky somewhere! Still, the level should be check again as well.
Alastair H. Thomas V. Joe D. Greg G. The install of the steering mirrors went really smoothly today. Alignment will for Y-Arm will begin this weekend.
Alastair H. Thomas V. Joe D. Greg G. A rough alignment for ITM-Y was done on Sunday using the temporarily attached TCS viewport, a tripod, and a laser. The alignment went really smoothly with the only roughness being fighting the SM2 mount. BSC 1 had the blank removed and was temporarily fitted with the TCS viewport. The TCS viewport has been failing leak test checks due to a leak issue with the viton seal and the wedged optics. Using a laser and a tripod mount we approximated the TCS periscope location and shot down to Steering Mirror 1 in BSC 1 then to Steering Mirror 2 in BSC 2 and back to ITM-Y. The next step is to repeat this for ITM-X when the BSC 3 door can be put up on the East side and the West door removed.
I have added python 2.7 and nds2 client v0.10.4 software to x1boot.
Patrick, Dave
To test reconnection rates of conlog vs edcu, h1susetmy model was stopped for 30mins this afternoon and restarted at 16:47.
Mitchell & I got the four Vertical Actuators attached. We got started on the Horizontal at Pier2 (SW) when we ran out of time, steam & opportunity--Thomas & MarkL were getting ready to head into chamber.

Work was performed under WP# 4256 which is now closed.This was performed in the scope of Bugzilla bug #385
Details are attached in log file.
We performed in the three-ring circus today. There were many items that needed to be craned into position in the LVEA in preparation for both this weekend's and next week's work: the Work Space cleanroom from the X Arm Spool area went to the south side of BSC1 for viewport installation, an additional work table and two shelving units for OFI assembly were needed in the West Bay and an enclosure was flown to the optical table at the foot of the mezzanine stairs for IO modification. All that activity took place this morning. Work related to the X End reconfiguration continued. The Work Platform was transported to Y End. The E-Module was picked, turned and placed by BSC5. The BSC Storage Container Top was hauled to the End to be mated with the bottom and then the entire unit was moved back to X Mid. The spool piece was transported from X Mid to X End and placed in the VEA. That concludes the dirty work on the checklist and the space is ready for a good cleaning on Monday morning. After lunch, we worked on modifying the Work Space cleanroom at the south door of BSC1 for TCS viewport install under clean conditions. The cleanroom and surrounding area were cleaned. Mark and Thomas started viewport installation at about 2:45 pm. Once Mark is done with that, he will make an entry into BSC3 to remove the dust/laser barriers so that BSC1-2 are accessible for TCS install over the weekend. The barriers will be stored in the west nozzle of BSC3.
Kyle Used LD to back "hung" 50 L/s turbo -> LD baseline at start of testing = 2.3 x 10-9 torr*L/sec helium indicated -> 20 sec audible helium blast at each gate annulus CFF joint on GV6 -> no response -> LD baseline at end of testing 2.2 x 10-9 torr*L/sec helium indicated -> Briefly energized annulus ion pump controller and observed expected cross-talk helium indication -> Restored GV6 annulus pumping to 50 L/s turbo backed by scroll pump -> Leaving GV6 hard-closed and will continue pumping combined annulus volume over the weekend
WP4225
I modified the h1iopsusb123 model to add ITMX into the software watchdog switching logic. At the request from Jeff K and Arnaud P, I ammended the WP4225 to include replacing the RMS+DC OSEM parts with the RMS-ONLY OSEM parts. Note these are temporary parts since they have their DC monitors completely removed. After the upgrade to RCG2.8 I will install the new OSEM parts which monitor DC but will not trigger on them.
The install procedure was: kill user models (h1susitmx, h1susitmy, h1susbs), restart the IOP, test the watchdogs to SEI BSC1,2,3, restart the user models. I pressed the DIAG-RESETs to clear latched IPC errors.
I modified the WD MEDM screens accordingly.
This closes out WP4225.
Kyle, Chris GV6 cammed hard closed during the night -> Vented combined annulus volume -> Removed 1.33-2.75 flex piping from North gate annulus pump port and installed blanks in its place -> Began pumping combined annulus volume -> Will helium leak test new joints after lunch GV6's 2-way selectable electro-pneumatic manifold was leaking instrument-air noticeably when left last night -> it is not leaking after GV6 has cammed closed. GV6's "unwillingness" to cam closed could be the result of insufficient net air pressure at the piston due to the excessive leak at the manifold or hard/non-compliant O-rings etc. or a combination of both, the important result is that it is not due to a "draped" gate annulus O-ring!
(Richard, Stefan) After some tail chasing (which included verifying that the spare PMC board works too), we found the 35MHz PMC EOM feed cable ripped out of the connector. Fixing this obviously restored all PSL functionality. A better connector is currently being installed. I also did a burt-restore to 10/26/2013 9am UTC (back when it was still working) to make sure we didn't pick up any spurious settings.
Phil fixed the connector - the PMC is now working again. The EOM cable length changed by maybe 2in in the process - we did not re-phase it now because the beam is needed for HAM2 work.
J. Kissel, D. Barker, J. Batch, A. Pele Another harrowing day of front-end code changes. In summary, I've now completed and committed all the simulink / front-end model, MEDM screen, and macro file modifications for the HLTS, HSTS, and OMCS. This involved several more recompiles, reinstalls, restarts, and restores of all 10 models involved, a couple of more crashes and restarts of the DAQ, and a whole lot of eye-crossing details. The final modification -- to the OMCS front-end code -- has crashed the h1sush56 front end again (as the rest of these installs have, save h1sush2a for some reason), and almost undoubtedly because of the usual mx_stream failure. Thankfully, if did not crash the rest of the DAQ, so data taking should still hold over night. Though I'm confident every thing I've done is legit, we should give a day to get things back up and running before we officially release everything to LLO. (Though I know they're not interested in more changes until they vent next Wednesday.) Of note -- It was not until I got to the MC_MASTER parts today, and getting some feedback from ISC folks that I realized -- for calibrated, interferometric control channel purposes (think IMC_X, PRCL, SRCL, MICH, DARM) -- we need to send out the output of each LOCK filter bank (including the top stage) to the top level to be sent over IPC to the OAF / Calibration model. For those SUS that aren't involved in global control, we'll just terminate the unused connections at the *top-level* of each model (currently only h1susmc2 is *actually* using this type of spigot to form IMC_X, the remaining IFO DOFs' control signals are pulled out for calibration in the LSC model). There are a couple of ways to do the calibrated channel thing; I'll bring up with ISC / Systems as to how we want to do it (because it's currently inconsistent across the ISC / IO models). Unfortunately, this means I've gotta go back to the QUADs and BSFM, but I'll wait for the discussion to conclude before I do so. Next on the chopping block -- tackle the severe upgrades and merging needed on the HAUX / HTTS models. Then that finally, finally, OMG finally, will close out this gosh darn ECR. Then we can do it all over again with the watchdog modifications. #facepalm.
It would be worth checking that scripts use to restart the mx_stream each front-end (such as /etc/start_streamers.sh ) are simplified to just do an mx_stream restart (i.e. /etc/init.d/mx_stream restart). The /etc/init.d/mx_stream script is customized to specify the MX slot and destination port on the the data concentrator. Old versions of /etc/start_streamers.sh did not call /etc/init.d/mx_stream but did their own restart that used slot 0, port 0 instead of unique slot/port.
CDS has brought all associated front-ends back up (see details in LHO aLOG 8424), and we've confirmed that we can get damping loops running and excitations can be sent out. As such, these modifications described above are clear of flaws, and are therefore ready for LLO to install.
