Update tinj to use CAL-PINJX for EPICs records
I've updated tinj.m to use CAL-PINJX_TINJ* instead of CAL-INJ_TINJ*. The new changes have been implemented at LHO.

The EPICs records changed are:
  * H1:CAL-PINJX_TINJ_STATE
  * H1:CAL-PINJX_TINJ_START
  * H1:CAL-PINJX_TINJ_ENDED
  * H1:CAL-PINJX_TINJ_TYPE
  * H1:CAL-PINJX_TINJ_ENABLE
  * H1:CAL-PINJX_TINJ_PAUSE
  * H1:CAL-PINJX_TINJ_OUTCOME

To do this:
  (1) Edited tinj.m to replace CAL-INJ_TINJ* with CAL-PINJX_TINJ*. The only exception was CAL-INJ_EXTTRIG_ALERT_TIME since ext_alert.py still uses this channel and has not been switched over yet.
  (2) At 20:57 UTC turned run_tinj off with the monit web interface.
  (3) Compile run_tinj using: mcc -R -nojvm -R -nodisplay -R -singleCompThread -m run_tinj
  (4) At 21:00 UTC turned run_tinj on with the monit web interface.
  (5) Commit changes.

I checked tinj.log and it was updating as expected.

We will need to coordinate the switch-over of CAL-INJ_EXTTRIG_ALERT_TIME to CAL-PINJX_EXTTRIG_ALERT_TIME. And update LLO to this version as well.

A few more channels set to be NOT MONITORED by SDF

Because Dave is finding that these are changing more frequently and thus causing him to commit more SDF snap files to the svn than he had originally planned for, I finished setting all of the SUS OPTICALIGN PIT and YAW channels (just 2 per each SUS) to not be monitored by the SDF.  I also started clearing house on the new BECKHOFF SDF.  In OBSERVE, this system sees more channel settings which differ from lock stretch to lock stretch.  The following were set to NOT MON in SDF:

H1:*-*_*_LIMITCOUNT (Counter channelswhich have just been incrementing since the begining of the run)

H1:ALS-C_COMM_VCO_CONTROLS_SETFREQUENCY (Changes by very small amounts from lock to lock for ALS locking)

H1 Optical Lever Re-zeroed

Today I re-zeroed all of the active H1 optical levers.  The table below shows their pitch/yaw values before re-zeroing and the values as they read when I finished each oplev (there could be relaxation in the motors causing a slow, slight drift, especially in the BS and HAM2 oplevs which are zeroed with piezo motors steering a 2" turning mirror).  This closes work permit #5606.

Beckhoff SDF system (running on h1build) needed a restart following problems with h1build. Note this was done in observation  mode, this is a pure EPICS monitor system which access the IOC via an EPICS gateway.

Yend noise sources

At about 10:15 this morning Bubba and I disabled the fridge and the outdoor AC unit at YEND. We also concluded that the trap primers at YEND are likely mechanical only and not electrically operated.

DMT update/restart completed
I have completed the update and restart of the dmt software. This includes generation of segments based on  ETMY-ESD DAC and DCPD ADC overflows and a few minor bug fixes. The restart also activates the calibration filter file changes made by Maddie.

Load issues causing DCS diskcache to freeze

Load issues seemed to cause the server running the diskcache to freeze ast night. Now it looks like the diskcache crashed soon after I rebooted the server. I'll restart it, and the summary pages should start to update again.

Couldn't lock ALS. Doing an initial alignment.

Unable to maximize the ALS transmitted power just by touching ETMs and TMS alone. ITMs didn't move much compared to where it was after the lockloss. COMM beatnote is low (3ish) and touching PR3 didn't improve it.

Another 5.4M earthquake from Greece coming through...... Pause the initial alignment.

nutsinee.kijbunchoo@LIGO.ORG - 01:49, Tuesday 17 November 2015 (23458)

We also just had a wind gust at ~50 mph. EQ band seismic is on the rise. Relocking is going to be a while......

First try relocking. Lockloss at REDUCE_CARM_OFFSET (11:02:17 UTC). Wind speed ~30 mph.

nutsinee.kijbunchoo@LIGO.ORG - 03:11, Tuesday 17 November 2015 (23460)

Wind reaching 40 mph. Locking seems hopeless right now. Just lost lock again at CARM_ON_TR (11:08:2 UTC). Put ISC_LOCK to DOWN.

nutsinee.kijbunchoo@LIGO.ORG - 04:48, Tuesday 17 November 2015 (23461)

I noticed SRC_CAGE_SERVO user message tells me to "Align SR3 to offload M2 actuators". I'm not what action to take but I've attached the cage servo output below. I also noticed OMC shutter was opened while locking DRMI couple of times. Could that have intefered with DRMI locking? I don't remember the shutter being opened that early.

Tidal still high. Relocking still unsuccesful.

Wind speed decreased to ~20mph. So I tried again. Lockloss while locking PRMI. Looks like ETMX ran away.

nutsinee.kijbunchoo@LIGO.ORG - 05:59, Tuesday 17 November 2015 (23463)

Wind speed is back to ~30 mph.

nutsinee.kijbunchoo@LIGO.ORG - 06:15, Tuesday 17 November 2015 (23464)

The forecast lied to me saying the wind speed would decrease towards the morning. The wind has been 30-40 mph since 10 hours ago with no sign of decreasing. LLO has been down also because of wind. I'm calling it a night (or morning?).

Shift Summary - Evening

TITLE:    Nov 17 DAY Shift 00:00-08:00UTC (04:00-00:00 PDT), all times posted in UTC

STATE Of H1: Down

SUPPORT: Jenne

LOCK DURATION: Lock clock had us at over 12 hours. Lockloss reset. Don’t know actual time.

INCOMING OPERATOR: Nutsinee

END-OF-SHIFT SUMMARY: IFO Down. Earthquake

ACTIVITY LOG:

02:56  I believe I heard a plane pass overhead.

05:28 Livingston lost lock about 20 minutes ago. I called Will in their control room and he reported that winds had picked up to 15mph. sheesh.

05:45  I noticed to back-back 45MhzRFAM glitches. There may have been a couple more since 35 minutes ago. The Omega graph doesn’t show glitchy activity prior to that. As of now it doesn’t seem to be chronic.

06:42 Winds have calmed down to ≤20mph. Mich Live is fidgety between 10Hz and 11Hz. I don’t see any RF45 correlations to this. Range chart shows Livingston dropping lock almost exactly that we have a very large glitch and after that, we’re a glitchy mess. The RF45 business from my previous log is part of that and there was one really large glitch that wan’t 45Mhz or a Saturation. Jordan is checking it out.

06:32 45RFAM glitching for 5 minutes straight.

06:38 With Livingston down I came out of Observing to try and reduce the RF Set on the EOM to try and settle the glitching down.

06:44 Glitches still seem to be present only not as prominent to us. ASAIR_B_LF_90 is becoming unstable looking. No saturations being reported.

06:55 Concerned about saving the lock, I called Jenne. There doesn’t seem to be any action to take regarding this issue other than to aLog it. While we’re talking RF45 is settling down. I’ll wait until our range is back to where it was previously before setting the intent bit back to observing.

07:34 Lockloss. 6.5mag earthquake off the coast of Greece. I have to laugh because after the really tough time locking y-arm last night, it was the first to lock right up despite all the ground motion while x-is still hopping crazy. Handing of to Nutsinee

Upon further inspection the 'one really large glitch' mentioned in Ed's summary is actually caused by RF45.

Compare: RF45 to strain
