I can not tell if the lights are on or off at mid X, mid Y or end X.

Winds are less than 10 mph.

From pinging:
CDS WAP is off at the LVEA, end X and end Y.
CDS WAP is on at mid X and mid Y.

Screenshots of the seismic bands and ISI blends are attached.

Ops Eve Summary: 00-08:00UTC, 16:00-23:59PT

State of H1: Observe

Fellow: Rick

Incoming Operator: Patrick

Shift Details:

• H1 locking when I arrived
• Calibration work by various people, JeffK, Jenne, Evan,...
• H1 into Observe, then button click took it out.
• H1 back to Observe at 4:04:42UTC
• no outstanding issues to pass on

Quiet and uneventful shift (as far as we can tell).   Cheryl kept the ifo. locked the whole time at close to 80 Mpc.  The range has trended down a few Mpc over the past seven hours or so.

We had a large tour group in the control room at around 7 pm.

We've finish the afternoon's worth of full IFO calibration measurements, including broad-band white noise excitation with PCAL into DARM (like LLO aLOG 22191) and true DARM / CARM excitations at given frequencies (like LLO aLOG 23184). We'll analyzed the data in the future, but the times for the injections are as follows:

(All times are 2016-01-09 UTC day)
36.7, 331.9, and 1083.7 [Hz] excitations of CARM 02:00:30 to 02:07:00 UTC
36.7, 331.9, and 1083.7 [Hz] excitations of DARM 02:10:00 to 02:17:00 UTC

Broad-Band excitation from PCALY 18:19:00 UTC to 18:34:00 UTC

Although we plan to analyze the data offline looking at much longer integration times, but .xml templates live here:
/ligo/svncommon/CalSVN/aligocalibration/trunk/Runs/PostO1/H1/Measurements/PCAL/
A       2016-01-08_H1DARM_PCALY_BBEXC.xml
A       2016-01-08_H1PCAL_TrueDARMCARM_Drive.xml
A       2016-01-08_H1PCAL_TrueCARM_Drive.xml
A       2016-01-08_H1PCAL_TrueDARM_Drive.xml

In addition, we also grabbed 5 minutes of data where we drive the 331.9 [Hz] line in both PCALX and Y, again in CARM and DARM, but *much* harder than normal, such that we can calculate the PCAL's relative calibration with excellent SNR and precision.

We've also turned on an X-end PCAL calibration line at 4001.3 @ 40000 [cts], which we intend to leave in place overnight (i.e. we'll accept in the SDF sysetm, and run it over night). This was turned on at roughly 04:02:00 UTC, attached is the screen shot. 
331.9 excitation of CARM 03:31:00 UTC to 03:36:00 UTC
331.9 excitation of DARM 03:38:00 UTC to 03:43:00 UTC

The other day while Sheila and I were trying to fix the dying-POP-power situation, we opened the beam diverters to see if we could tell something about the alignment from the image of the REFL beam.  However, since we usually run with the beam diverters closed, neither of us could remember the precise shape and relative brightneses of the REFL beam in full power.  So, since data is currently being taken with the beam diverters open in NLN (non-observing), Cheryl and I took a photo!

Attached is a photo of the REFL beam on the upper of the 2 analog tvs in the front of the control room.  Currently, POP_A_LF_OUTPUT is about 16,200 counts, which is pretty normal, and corresponds to a recycling gain of a little more than 41.

• We were plagued with a decreasing POP power which made locking for long periods of time unstable, many fixes were attempted such as re-alignment of the recycling optics and the test masses. The silver-lining was that we were given opportunities to fix a few problems while trying to relock.
  • ALS fiber polarizations were re-adjusted Travis
  • Mich Dark was fixed by Kiwamu
  • Recycling gains were optimized by Sheila, Cheryl, and Jenne
• This Tuesday was the start of calibration measurements during the day.

TITLE:  1/8 DAY Shift:  16:00-00:00UTC (08:00-04:00PDT), all times posted in UTC     

STATE of H1:  On the way to NLN

Incoming Operator:  Cheryl

Support:   Jenne, Evan, Kissel

Quick Summary:

Calibration work continues.  In the afternoon spent some time locking H1 & this was not trivial due to:

1. 5.3 Mexico quake
2. PRMI transition not working as desired
3. Power not raised to 23 W (script was changed last night, but was not loaded)
4. Also having issues with either the operator workstation and/or Guardian

Shift Activities:

• 16:00 calibration work
• 16:30 alog reboot
• 16:40 MY piping work (Bubba)
• 17:09-17:16 Optics Lab visit (Joe D.)
• 17:58-18:25 MY trip (Kyle to talk to Bubba)
• 18:05 H1 Lockloss (unfortunately before Kissel finished his last measurement)
• 18:10 - 20:40 PCal Team heading to EX (Darkhan, Travis, Evan)
• 18:16-19:23 EY charge measurements begin (Betsy)
• 20:44 - 21:35 EX charge measurements begin (Betsy)
• 21:40 -22:04 Initial Alignment
• 21:05 -  Locking
• 21:10 5.3 Mexico Earthquake
• Handing off an H1 which is hopefully now ready for NLN!  :)

This afternoon have noticed the Guardian screens going WHITE & have also had medm message windows saying:  "virtual disconnect" for h1guardian0.  Jim Batch checked this and mentioned that h1guardian0 has a scary amount of Network Connections (or something along those lines).  Attached is a snapshot when I lost guardian.

An additional symptom I'm seeing is with the actual work station (logged in as ops-->  ops@operator0).  The desktop has frozen up a few times.  I have rebooted this computer multiple times.  Will send an email to cdsadmin.

This afternoon, there was a window of opportunity to take ETMX and ETMY charge measurements.  Results are posted below.  Kissel is suggesting that I add another plot, but since it will take a while to work through I'm deferring to Monday, sad as he now is.  Charge is still accumulating and we need to think about flipping the bias soonish.

This AI chassis was removed as mentioned in the following alog entry
  https://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=21081

In seeking to find what was wrong with the chassis, I powered it up.
The following output channels were glitchy when their respective inputs
were terminated:
 Channels: 1, 3, 6, 8, 9, 10, 11, 14 and 16

Don't know why yet but the AA/AI boards (D070081-v6, S1103146, S1200704)
are a little warmer to the touch than usual (I think).  Channels [1-8]
are on S1103146, channels [9-16] are on S1200704.

EvanG, Travis, Darkhan,

Today we repeated Pcal end-station measurements at EX, the procedure is described in T1500063. Rough readings from dataviewer and GPS times are given in the attached notes.

The outer beam still show a significan drop in power between Transmitter and Receiver modules, earlier we thought that the beam was not well centered at the input port of the RxPD integrating sphere, but by looking at an outer beam spot with IR viewing card it does not look to be the case (see attached picture).

Earlier this week we took a similar set of measurements, but we suspected that WS/TX when WS is inside of received module were not taken properly and today's measurements were taken as a double-check (LHO alog 24726).

We will post a full report and some conclusions soon.

We've continued measuring the beam spot positions once a week as part of Tuesday maintenence. 

The 2 pdfs below are different views of the same data set.  The first set of plots is the data on x-y grids, so you can really see how little our spots are moving.  The second set of plots is the data as a function of time.  Some of the pitch values are changing more now than they were back in October, but the maximal excursions are still only about 2mm away from the means.

I started welding the turbo header piping under the beam tube at Mid Y back together today. The first weld was started at approximately 10:17 PT and lasted for ~45 seconds. The next welds were at ~10:36 and 10:46: PT and each lasted for ~ 90 seconds. There will be more welding next week.

FRS #3896

The ~hinj account on h1hwinj1 is now being backed up to the daqsvn.ligo-la.caltech.edu computer every hour.  This should close out FRS ticket.

Found h1nds0 to be dead with a kernel panic, rebooted.  Did not cycle power, just reboot.

RickS, Darkhan,

Yesterday, Jan 5, 2016, we took Pcal end-station calibration measurements at EX using WS1 calibration standard. The measurement procedure is described in T1500063.

Rough numbers from dataviewer and GPS times were noted in the attached scan (blank form is taken from T1500062).

A generated report (comparison with previous measurements) was uploaded to DCC T1500129-v3.

At first when we started the measurements we found out that laser power in PcalX is modulated through Pcal hardware injection channels H1:CAL-PINJX_*, we had to restart the measurements after tuning off these excitations.
