WHAM6 completed this afternoon. Note--Swapped out old Capacitive Position Regulator Board D1001474-v1 for a v3 model. This was on the CPS2 Satellite Chassis. The platform Isolated with no issue.
So now all the LHO CPSs are on the 71 MHz timing sync. WP 5773, FRS 4554 aka II 1058, ECR E1500244, D1400363
After the weekend of quiet, I'll compare befores and afters.
John, Gerardo, Chandra Opened the diagonal volume to the turbo pumping station at 10:00 local time (PDT) at 0.8 Torr. Current pressure is below pirani range but cold cathode won't turn on yet.
Gerardo, John, Chandra Leak checked: Full range gauge conflat on BSC7 Full range gauge conflat on BSC8 Two viewports on X spool Two viewports on Y spool No leaks found! Background on X was 1.0e-9 Torr-l/s Background on Y was <1e-11 Torr-l/s Sprayed each flange with helium for 20 sec.
11:03 EX transitioned to LASER HAZARD.
Re WP 5774 FR 4694 (PKA II 1193)
To offload the ISI witness point motion calculation from the SUS to the ISI which runs slower and has more computation headroom. See 25913 for original update to ISIs--the SUSPOINT being the important thing. Looked at comparing the calibration of the ISI motion in the SUS 16k machine vs the 4k ISI machine in LHO aLog 25993--Jeff & I may look more closely at this but we think all the differences are explainable. The original updated library parts were modified to capture the data in frames--see 26128. After restarting the ITMY model to test these changes and adapting the implementation for ISIs which have multiple suspensions (See Attached) earlier this week, yesterday, 17 March, the remainder of the BSC ISI were restarted. All restarted fine--26117.
This morning, the Calibration filters have been loaded and following JK's aLog 4553, I've populated all the new BSC ISI CARTESIAN to EULER matrices.
I believe this means that DetChar can repoint the detchar plots from the SUS model to the ISI models. Once there and we are happy, the SUS calcs can be removed.
The new channels are H1:ISI-{isi}_SUSPOINT_{sus}_EUL_{euler dof}MON where
isi = ITMY BS ITMX ETMX ETMY
sus = ITMY BS ITMX ETMX ETMY TMSX TMSY [The TMS projection matrices are identical to the ETM's so there is no new info there at the moment.]
euler dof = L T V R P V
Ah ha! I see that the TMS matrices on the SUS do have values distinct from the ETMs. I will update the database
/opt/rtcds/userapps/release/isc/common/projections/ISI2SUS_projection_file.mat
to include the TMSs and correct the ISI CART2EUL TMS values shortly.
Okay, I've changed the values for the ISI ETMs CART to TMS EULER matrices to be the same as the ones in the SUS CART2EUL matrices. I have not updated the database .mat file.

h1conlog1-master has still not connected to 1736 channels since the maintenance work yesterday (alog 26112). I checked the unmonitored channel list and with the exception of two, they are all of the channels that are not read-only in /opt/rtcds/lho/h1/target/h1ecatc1/h1ecatc1plc1epics/autoBurt.req, that is h1ecatc1 PLC1. The two other channels are H1:PEM-CS_DUST_LAB1_ENABLE and H1:PEM-CS_DUST_LAB2_ENABLE, which I confirmed do not respond to a caget. I can do a caget from h1conlog1-master on the couple of unmonitored channels on h1ecatc1 PLC1 that I tried. It is also worth noting that conlog-test-master has the same issue with the same channels. I tried restarting conlog-test-master and it still does not connect to these channels.
Dave restarted the gateway and it didn't help.
Solved. It turns out that the autoBurt.req file for h1ecatc1 PLC1 had windows line endings which Conlog does not like. This was probably because I had to copy that file over with WinSCP by hand instead of using Daniel's script which must do something to change the line endings (see alog 26072). Dave installed and ran dos2unix on the autoBurt.req file, I recreated the conlog channel list with it, and told Conlog to use the new channel list. Conlog removed the names that had windows line endings and added the ones that did not.
09:48 EX transitioned to LASER HAZARD.
I completed this Monday and this is a copy of the SEIlog I posted:
These library parts needed a couple modifications once downloaded from the SVN.
From the CAL filter bank, 1) Added the OUT channels to the frames and 2) Removed the redundant TP pick off.
From the Cart to Euler section, added the Euler motion to the frames.
See attached for final look at parts. Commited to svn rev 12874.
07:27 EY has transitioned to LASER SAFE.
TITLE: 03/18 Day Shift: 16:00-00:00 UTC (08:00-16:00 PST), all times posted in UTC STATE of H1: Planned Engineering OUTGOING OPERATOR: Mar CURRENT ENVIRONMENT: Wind: 10mph Gusts, 6mph 5min avg Primary useism: 0.09 μm/s Secondary useism: 0.20 μm/s QUICK SUMMARY: Taking shift for TJ as he is out sick today. CFC error on H1ISIBS. Loaded coefficients to clear.Light Pipe UN-shuttered. IMC re-locked at 15:29UTC. Peter to EY to transition to LASER SAFE.
Had crashed sometime earlier. Set to use the same 100726 channels as h1conlog1-master.
Closed safety valve and manual o-ring valve to QDP80 (still running) and will resume pumping on diagonal tomorrow morning. Current pressure = 1.9 Torr
Activity Log: All Times in UTC (PT) 23:00 (16:00) Take over from TJ 23:47 (16:47) Filiberto out of LVEA – The PSL light pipe is now open. End of Shift Summary: Title: 03/17/2016, Evening Shift 23:00 – 07:00 (16:00 – 00:00) All times in UTC (PT) Support: N/A Incoming Operator: N/A Shift Detail Summary: No commissioning work scheduled for tonight. Ops support not needed.
Installed interface boxes on the following table enclosures:
TCSX, TCSY, ISCT1, IOHT2R, IOHT2L, ISCT6, and TCSHT4R.
TCS tables still need panel faceplates. This completes the LVEA, and will continue tomorrow at the end stations. EX will need to be transistioned to laser hazard.
The interfaces boxes will monitor the open/close status of doors and panels on table enclosures.
1/2 open LLCV bypass valve, and the exhaust bypass valve fully open.
Flow was noted after 10 minutes and 10 seconds, closed LLCV valve, and 3 minutes later the exhaust bypass valve was closed.
Next over-fill on Saturday, March 19th before 23:00 utc.
The manual valve setting was increased from 15 to 18% to help compensate for this increased boiloff.
Log for work done Monday March 14 under WP 5776 and WP 5777. The BSC7 X2 PT170 and BSC8 Y2 PT180 Pirani and Cold Cathode vacuum gauges were replaced with Inficon BPG402-SE EtherCAT vacuum gauges. Filiberto connected these to the second EtherCAT port of the h1ecatc1 computer: 'h1ecatc1 (in MSR) Local Area Connection 4' - 'ethernet cable' - 'CU1521 EtherCAT media converter (Multimode) (in MSR)' - 'fiber cable' - 'CU1521 EtherCAT media converter (Multimode) (in LVEA)' - 'ethernet cable' - 'CU1128 EtherCAT junction box (in LVEA)' The CU1128 EtherCAT junction box has 8 ports: Port 1 is the incoming connection. Ports 2 and 3 were left empty. BPG402 on BSC7 (Box 294 in the system manager) was connected to port 4. BPG402 on BSC8 (Box 295 in the system manager) was connected to port 5. Ports 6, 7 and 8 were left empty. I added channels for these in PLC1 and updated the system manager. I committed the changes to svn and restarted everything. I may have also gotten some changes that Joe B. committed to svn for PLC3 (see attached screenshot). When I restarted the EPICS IOC the script that automatically copies over the generated error medm screens, INI and autoburt request files failed. A screenshot of the error is attached. I used WinSCP to copy over the INI and autoburt request files by hand. The following channels were added for these gauges: H1:VAC-LX_X2_PT170_PRESS_VALID H1:VAC-LX_X2_PT170_PRESS_OVERRANGE H1:VAC-LX_X2_PT170_PRESS_UNDERRANGE H1:VAC-LX_X2_PT170_PRESS_TORR H1:VAC-LX_X2_PT170_PRESS_SENSOR H1:VAC-LX_X2_PT170_PRESS_TRIP H1:VAC-LY_Y2_PT180_PRESS_VALID H1:VAC-LY_Y2_PT180_PRESS_OVERRANGE H1:VAC-LY_Y2_PT180_PRESS_UNDERRANGE H1:VAC-LY_Y2_PT180_PRESS_TORR H1:VAC-LY_Y2_PT180_PRESS_SENSOR H1:VAC-LY_Y2_PT180_PRESS_TRIP
The failure of the script to copy over the files was because /opt/rtcds was not mounted on opsws3 due to the file server change over.
