Nds2 client 0.14.3 has been deployed on the Debian 8 boxes.
This is a bug fix release to fix problems when you are streaming nds2 data from disk, in the presence of gaps.
HAM2, RZ = -246urad
HAM3, RZ = -166urad
WHile the lower stage AOSEMs were pulled back over the last few days on SRM, I did a quick look at the dark offsets. Of course, the "pretty" OSEM offset script wouldn't work due to many years of CDS software tool upgrades since it's last uese (thanks Jim for tyring), so I just ran them by hand, and plugged them into the associated MEDM screens:
M2
| NEW OLV | OFFSET WAS | OFFSET NOW | GAIN WAS | GAIN NOW | |
| UL | 24350 | -13573 | -12175 | 1.105 | 1.232 |
| LL | 23240 | -13887 | -11620 | 1.08 | 1.291 |
| UR | 24350 | -13423 | -12175 | 1.118 | 1.232 |
| LR | 21780 | -12388 | -10890 | 1.211 | 1.377 |
| M3 | |||||
| UL | 22240 | -13741 | -11120 | 1.092 | 1.349 |
| LL | 23100 | -12966 | -11550 | 1.157 | 1.3 |
| UR | 23160 | -13527 | -11580 | 1.109 | 1.295 |
| LR | 20850 | -12420 | -10425 | 1.208 | 1.439 |
The OSEM strengths look to be decaying a bit.
Also, I set the pitch and yaw alignment sliders both to 0 since it is getting a fresh start. (Bias sliders were P=-666.3, Y = 927.4)
For the record, I've accepted these new open light current values for SRM into the safe.snap of the SDF system this morning, such that they survived the h1sussrm front-end process reboot to remove the HAM5 optical lever (see LHO aLOG 38868). See attached screenshot.
Today Travis and I used the ergo arm to install the new ITMx optic (ITM07) into the QUAD lower structure parked in the biergarten. Thanks in advance to Jeff K for the photo shoot session he performed during this (see attached). We put a few more laser barrier walls in place and firmed up the layout of the space so that Jason can start loading in and setting up IAS survey equipment needed for the fiber welding. We also added the temporary "back stops" tooling fixture to the AR side of the ITM optic since the "real" stops are on the reaction chain structure across the room.
Note - prior to installing the new test mass, Travis tidied up the PUM horns, and I wiped the PUM and the entire structure to remove particulate likely generated from the disassembly of the suspension (mostly metal flakes observed in the wipes and on surfaces). First Contact is still on the HR and AR optic surfaces of ITM07.
Thanks to Bubba and Mark for craning the ergo arm and the engine hoist out of the biergarten in order to help us with some tight real estate issues. Also thanks to Christina and crew for cleaning all of those black laser panels yesterday.
J. Kissel, for T. Sadecki and B. Weaver Attached are: - Highlights of the install, full res pictures - Full set of install pics, in order (smaller sized 2017-10-03_H1SUSITMX_ITM07Optic_Install_Pics.pdf) - A few bonus collections of the PUM and UIM (also reduced in size) Let me know if you want any of the originals of the non-highlights.

Today we installed the TMDS flanges & mini gate valves on BSC 1,3 chambers. Installation on BSC 1 was straight forward, per drawing D1500174. Installation on BSC 3 is rotated down 7.5 deg from the designed clocked orientation due to existing fixed bolt pattern on door port. Calum and Eddie verified in SolidWorks that the angle of attack is still effective in this orientation.
Robert pointed out that remote access ssh sessions were still showing the text that operator intervention is needed to log into LHO CDS. This is not the case outside of observation runs and I have corrected the text accordingly.
The ASC, SUS and ISI model changes required a DAQ restart, which I did in two stages.
The first DAC restart at 10:34 followed restarts of the models h1asc, h1ascimc, h1isiham2. The ASC restarts were to resync the models with the modified H1.ipc file for the SHMEM IPC channels between h1ascimc (sender) and h1asc (receiver).
I took the opportunity during this restart to reboot h1tw1 which had been running in excess of its 208.5 day limit.
The second DAC restart at 11:33 followed the restarts of the models h1isiham[3,4,5], h1sus[mc2, srm].
I renamed the partial second trend files for both restarts to correct the NDS1 second trend plots which span this time region. For those interested, the attached plot shows a two hour second trend of a model's cpu usage before, during and after this frame file correction. The left plot shows the data dropping out after 30 minutes as an incorrect channel is substituted. The middle plot shows the 30min mark fixed (replaced with a 10 min gap) but a data drop at the 90 min mark. The right plot shows contiguous data excpet for the two 10 minute gaps.
J. Kissel, D. Barker ECR: E1700123 FRS: 7844 As one of the last steps to decommission the HAM ISI optical levers, Dave and I have removed the top-level ADC calls and IPC communication between h1susim > h1isiham2 h1susmc2 > h1isiham3, h1isiham4 h1sussrm > h1isiham5 We have not yet made the final change, removing the inputs and corresponding processing guts from the isihammaster.mdl. We'll coordinate that removal with LLO. (No screenshots to show, since this only involved the removal of parts.)
Attached are the VPW desiccant plots with this month's added data. Nothing out of the ordinary shown.
Ran check script to verify all dust monitors in the LVEA are running. Plot below are the particle counts for the past 7 days. All cleanroom counts look good. The big spike in HAM6 is associated with the door removal. The counts quickly drop back down to near zero shortly after the door removal is finished. ** The monitor at HAM5 appears to have taken a tumble and shows signs of damage. I am going to swap it out as the counts from the 0.5um particles are a bit suspect.
This morning I completed the weekly PSL FAMIS tasks.
HPO Pump Diode Current Adjust (FAMIS 8442)
With the ISS OFF, all operating currents of the HPO pump diode boxes were increased by 0.1 A; the changes are summarized in the below table. A screenshot of the PSL Beckhoff main screen is attached for future reference.
| Operating Current (A) | ||
| Old | New | |
| DB1 | 50.4 | 50.5 |
| DB2 | 52.9 | 53.0 |
| DB3 | 52.9 | 53.0 |
| DB4 | 52.9 | 53.0 |
The operating temperatures of the diode boxes were not adjusted. With the ISS back ON, the HPO is outputting 153.7 W. This completes FAMIS 8442.
PSL Power Watchdog Reset (FAMIS 3670)
I reset both PSL power watchdogs at 16:19 UTC (9:19 PDT). This completes FAMIS 3670.
Bubba G., Mark D., Kyle R. and Rakesh K. "Bumbped" non-suspended component of NE HEPI when N. door separated from HAM6
These are the particle counts taken by the door team for the HAM6 door removal. The counts were a bit high for the north door when it popped but not too bad. One did not see the same disturbance when the south door "popped" as the pressure in the chamber had already equalized to atmosphere.
Both the crystal and diode chiller filters in the Chiller Room (e.g. not under the table in the PSL enclosure) look good. No discoloration or notable debris observed. Closing FAMIS #8301.
Added 300ml water to Crystal chiller. Diode chiller water level light is not on; therefore did not add additional water. Both filters look good.
J. Kissel H1 ISI HAM5's tuned mass dampers have been retuned to match the first bending mode of HAM ISI blade springs post spring-tip-damper install (~139 Hz). Attached are the results for all three TMDs (pg. 1: before and after tuning; pg. 2: after tuning, compared against the blades). The retuned TMDs will be installed at the earliest convenience of Jim and Hugh. Details of the measurement setup are as described in LHO aLOG 38741.
J. Kissel, for J. Warner H1 ISI HAM5 Corner 2 and 3 TMDs are re-installed. That includes re-installing all walls associated with Corners 2 and 3. The only ISI damping mechanism work that remain on ISI HAM5 are re-installing the TMD for the corner 1 blade, and installing the GS-13 Can Damper on the H3 can. First image is Corner 2's re-installed TMD placement, and Second image is Corner 3's.
J. Kissel, for S. Cooper and J. Warner Corner 1 TMD was re-installed today, 2017-10-02.
I don't know what would have caused this alignment shift but the CPS signals don't look real. At 16:48 UTC Oct 2, there is a shift in both HAMs 2 & 3 at the exact same moment. First attached image is the full time series trend for the CPS RZ location (nrad) for both chambers for the minute containing the shift. Otherwise, neither Hugh nor I have done anything with the chambers, they haven't been unlocked since the vent. I'm having a hard time imagining a physical event that would move these chambers in this way at the same time. Second plot shows the RZ locations for the last ten days. Other than the jump on Oct 2nd, they don't look like they have moved since being locked.
Adding:
The GS13s also don't seem to see anything. Third trend is the same time as the first, showing both CPS and GS13s for the chambers.
With the chambers locked we took the Sync chassis down to move some power around. There was not movement. The chassis is powered up again but will require more down time. We will make it brief.
