Attached is a plot of the reference cavity transmission and room temperature.  Also plotted are
the quadrant signals from the quadrant photodiode in the ISS box.  The transmission didn't
deteriorate too badly after yesterday's tweak.

The second plot shows the pre-modecleaner temperature and the output of its heater.  Whilst the
heater's job is to keep the pre-modecleaner PZT voltage within its range, it does appear that
the lengthening of the body couples to the pitch (mostly) of the output beam.  THis might be due
to the way the pre-modecleaner body is clamped to its container.

Title:  12/02/2015, Evening Shift 16:00 – 00:00 (08:00 – 16:00) All times in UTC (PT)
	
State of H1: 08:00 (16:00), The IFO locked at NOMINAL_LOW_NOISE, 22.2w, 81Mpc.  

Outgoing Operator: TJ

Quick Summary:  IFO locked in Observing mode for the past 15 hours, with exceptions for commissioning mode as noted in the aLOG. Environmental conditions are good – wind is calm (0-3mph), seismic activity quiet.   

• Title: 12/2 OWL Shift: 08:00-16:00UTC (00:00-8:00PDT), all times posted in UTC
  

• State of H1: Observing at 77Mpc for 16hr. Bubba still on tractor clearing snow.
  

• Shift Summary: Boring shift (a good thing!) except for the snow.

• Incoming Operator: Jeff B

• Activity Log:

• 12:16 - Out of Observing to clear timing error
• 12:16 - Observing
• 13:34 - GRB
• 15:06 - Tractor clearing snow in the parking lots, dip in range.

At 15:06 UTC Bubba told me that he was headed out to clear the parking lots of snow. Since then there has been about a 5Mpc drop in range. Coincidence?

LLO lost lock, so at 12:16 UTC I brought the IFO out of Observing, cleared the timing error on H1SUSETMY, and then went back into Observing.

Observing 78 Mpc for 12 hours. Snowing.

There is a little over an inch of snow on top of a bit ice from freezing rain on site. If you are coming on site this morning please drive safe and slow. I'm not sure if Route 10 has been plowed, but I have seen a few cars heading to Hanford.

J. Kissel

I've taken new DARM Open Loop Gain and PCAL2DARM transfer functions for the bi-weekly(-ish) full-frequency-span confirmation of the time variation in calibration / IFO parameters. As a by-product of these two transfer functions, we're able to confirm that the front-end, CAL-CS, DELTAL_EXTERNAL calibration (and therefore the low-latency GDS pipeline output) is still within the desired precision. I attach screenshots of the measurements. They will be processed in greater detail tomorrow, once we have the evening's kappa values (i.e. what the calibration lines are telling us the systemaic errors are in the model parameters). Stay tuned, but things continue to look exquisite. Great job CAL team!

End of Shift Summary:

Title: 12/01/2015, Day Shift 16:00 – 00:00 (08:00 – 16:00) All times in UTC (PT)

Support: Kiwamu
 
Incoming Operator: Travis

Shift Detail Summary: 16:00 (08:00) Start Tuesday maintenance window.
After maintenance window tried to relock. Green alignment bad. Realigned green and tried relocking. Found BS alignment was off. Did full initial alignment and tried to relock. Had a problem with OMC not finding carrier. Kiwamu found lower limit of carrier detection was too tight. He changed it in Guardian from 10% to 25% (which matches the upper limit). Continued with relocking and reached NOMINAL_LOW_NOISE. IFO is in observing mode while Kissel runs measurements.

Today's plan was to go out to TCSX table, take out the old IR sensor, and replace it with the new one (+VP inspection). John wanted to make sure that the sensor actually does what it was designed to do before we unwrap the light pipe and put it in so we did some tests. The comparator box was thought to be calibrated to trip at ~45 degree C. However, I forgot to write down how I did it so the number was very shady... We waved a small soldering iron in front of it, starting at low temperature (~150 deg F). The box would trip when the soldering iron was waved at half a centimeter away from the sensor. Keep in mind that the sensor is mounted at ~2.5 inches away from the center of the viewport with a small angle (the sensor is looking straight down while the optical window is about 0.6 cm deep under the viewport cover. So, the sensor must be able to trip when seeing a heat source at 2.5" away with ~22 deg viewing angle. We did a quick test by waving the soldering iron in front of the sensor with several temperature settings at several distances (At this point the potentiometer was about a quarter turn away from the room temperature tripping point. It's a 10-turn pot!). 800 deg F setting tripped the box at ~3" away, 600 deg F and 500 deg F tripped the box when waved at ~2" away. But these temperatures are impractical settings. At 800 deg F, 3" away we were able to make the box trip when placed the soldering iron rounghly 1cm above the sensor's viewing axis. This gives as a viewing angle of ~8deg, about a factor of 3 less than what's required. We did the same test with the sensor that was mounted on the TCSY viewport. The results were similar (400F, 500F soldering iron didn't trip the sensor when places at the center of the viewport but tripped the sensor when moved to the edge of the viewport. 600F at the center of the viewport did trip the sensor.)

To confirm the temperature of the soldering iron we used to do this test, we used Richard's FLIR camera and a thermocouple. Turns out the actual temperature of a certain spot on the soldering iron we pointed the IR sensor to was lower than the display. The thermocouple measured 304 F when display reads 350F, 630 F when reads 700F, and 750F when reads 850F.

Conclusion: The sensor unit isn't doing what's it supposed to do and we should rethink about installing them without an improvement to the comparator box circuit. Note that we were only using half a turn out of 10 turns available on the pot to set up this test. There's no way to fine tune this thing to where we want it to trip!

Last Tuesday (24th Nov) Jim and I modified the monit on h1hwinj1 machine such that when it restarts the psinject process it smoothly ramps the excitation amplitude over a time period of 10 seconds. We manually started the new system on Tuesday and since then there have been no crashes of psinject until the last 24 hours. There have been 4 stops (with subsequent automatic restarts) in the past 24 hours, each stop was logged as being due to the error:

SIStrAppend() error adding data to stream: Block time is already past

Here are the start and crash times (all times PST). Monit automatic restarts are maked with an asterix

Calibration parameter updates that includes data until Nov 11.

Kappa_tst is slowly trending up after the bias sign flip on Oct 16  and rest of the paremeters show normal variations that we have seen in the past.

The first plot contains all the parameters that we calculate. 

The second plot highlights kappa_tst, kappa_C and cavity pole of which the kappa_tst and kappa_C will be applied to h(t).

This data is filtered for locked state using GDS state vector and thus contains some outliers at times when the IFO is locked but not in anlaysis ready state. In  future, we plan to use GDS state vector which will give us the flexibility to only use analysis ready data.
