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

State of H1: Observe, range 79Mpc, POP_A_LF stable

Fellow: Darkhan

Shfit Summary:

Calibration measurements until about an hour into my shift

Locking went well, and made it past DRMI

Calibrations needed H1 in not-DRMI, so I broke the lock

Calibrations continued, then back to locking

Even after having been out of lock most of the day, H1 locked and went back to Low Noise

Relocking Issues:

• find IR in both DIFF and COMM needed to be helped in order to stablize the are power
• first lock broke right after ENGAGE ASC part 3, so subsequent locks I paused at each ASC part
• power only went to 10W - something Sheila and I had changed while troubleshooting H1 yesterday
• IMC SDF showed up during the lock

Changes: 

I restored the gaudian to requestion 23W instead of 10W. JeffK had suggested it, and I emailed Sheila, and she said to go ahead.

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

The 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.

nds0 is down and the EDCU is red.

Screenshots of the seismic bands and ISI blends are attached.

We're too exhausted to write the aLOG this deserves, so we'll just say "we did it!" and leave plots and conclusions until tomorrow. The message: from what prelimiary analysis plots we have made, we can say that these new results are consistent with those taken during ER8, modulo the well-tracked change in kappa_{TST} (the EY L3 ESD actuation strength). Stay tuned!

We can also say that using ALS DIFF instead of a single arm locked on red has drastically improved the statistical uncertainty of the Free Swinging Michelson method -- thanks LLO!

Manually filled CP3 -> Opened exhaust check valve bypass -> Opened LLCV bypass valve 1/2 turn ccw -> LN2 evident at exhaust after 29 minutes 30 seconds -> Closed LLCV bypass -> Closed exhaust bypass valve after several minutes -> Confirmed with Gerardo that we are performing this exercise following the same prodedure -> I cannot explain the discrepancy between the fill times between today vs. the previous fill unless the LLCV bypass valve's stop-to-stop is very course and our "1/2 turns" differ significantly.  

Next manual over fill of CP3 is scheduled for Saturday before 4:00 pm

Scheduled Injections

During this time period, 12 scheduled injections were found to have occurred

• CBC 1134345924.000 (coherentbbh10_1128678894_)
• CBC 1134348928.000 (coherentbbh11_1128678894_)

• BURST 1134581196.000 (WNB_burst_1134573920_1_)

Only 1 injection was found to not occur:

• BURST 1134577813.000 WNB_burst_1134573920_1_

Network and IFO Injections

Of the occurring scheduled injections, only two occurred as single-IFO injections:

• CBC 1134357333.938 (L1) (coherentbbh18_1128678894_)
• CBC 1134348934.048 (L1) (coherentbbh11_1128678894_)

All other scheduled injections occurred as H1-L1 coincident injections. The only UNSCHEDULED injections were 5 CALRESETs at L1 and 1 CALRESET at H1.

Discussion of Anomalies

The CALRESET injections have the same pattern of occurring with only certain paired combinations of the frame flags indicated by HWInjReport, as seen previously. However, all of the occurring scheduled injections have the anomaly of not occurring in the CAL-INJ channel and not having the TRANSIENT bit set to “off” to indicate the presence of a transient injection. They do occur, consistently, in the ODC-MASTER channel for HOFT, RAW, and RDS frames and the GDS-CALIB channel for HOFT frames.

Per Operator Shift Checksheet activity for Thursday Task, I topped off the Crystal Chiller by adding 175mL of water.

TITLE:  1/7 DAY Shift:  16:00-00:00UTC (08:00-04:00PDT), all times posted in UTC     

STATE of H1:   OBSERVING (but taken out at 8am for calib)

Outgoing Operator:  Jim

Quick Summary:

As I walked in, H1 was in Observing, but Jeff was staging for his first Calibration measurements, which promptly started at 16:00UTC.  Also heard from Joe B. at LLO and how they are also starting as well.  

At the moment both interferometers are up and running for calibration work.  In the LVEA the useism continues to be high at about 0.75um/s; virtually no winds.

1/7 Owl Shift 08:00-16:00UTC

State of H1: Observing 80Mpc

Shift Summary: Quiet shift. Locked at 9:00UTC, not much else to report

Quiet shift so far. Locked about 9:00 UTC, been in Observe since. Wind is low, microseism is high, range is ~80MPC. POP bleed off seems to have been resolved after the work earlier today. 

[Jenne, Kiwamu, Sheila, JeffK]

Today, the interferometer decided that it didn't want to go from ASC_PART2 to ASC_PART3 without some hand-tuning each lock.  However, after some investigation, it's still not entirely clear what the right thing to do is :(

The things we were playing with were the offsets in the CSOFT and DSOFT pitch filter banks (can only be tweaked *after* the loops are on, since there's an integrator always on in each of those filter banks) and the transmon qpds' ASC-[x,y]_TR_[a,b]_[pit,yaw]_OFFSETs.  These things are kind of the same, but you need to adjust the transmon offsets if you want to do some adjusting before the loops are closed, and you need to adjust the CSOFT and DSOFT offsets if you want to do some adjusting after the loops are closed.

We've had locks where we didn't survive if we didn't re-zero the qpd offsets before going to part3, and we've had locks where we didn't survive part3 if we didn't adjust the CSOFT and DSOFT offsets.  But, we've also had locks where the opposite was true.

Anyhow, at this point, I think our advice is to try going through the guardian like normal (no by-hand offsetting), and if that fails one or more times, call a commissioner (it's me for now, so please call).  For example, the last lock, I re-set the qpd offsets during asc part 2, but forgot to engage the CSOFT and DSOFT offsets, and we seemed to be just fine.  So, it's not totally clear yet what the final prescription should be.

In efforts to finally nail down the mysterious "zero" around 50 [Hz] in the UIM (see LHO aLOG 24296), I've measured the TOP, UIM, and PUM driver using three different measurement configurations. The hope is that, with this "matrix" of differences, we can find out what's going on with the UIM to see if its something specific to the driver, or specific to the OSEM chain upstream of the driver. From what I've seen watching the measurements go by on the SR785, both the TOP and PUM stage show similar zero-like behavior as the UIM, though the TOP mass has a pole-like behavior above the zero and eventually rolls off. Both the PUM and the UIM look as though they are rolling up to "infinity" by 10 [kHz], without even a phase shift indicating their might be a pole "soon" in frequency.  More detailed analysis and plots to come.

The data has been committed to the repo here:

EYUIMDriver/2016-01-05/2016-01-05_EYPUM_Measurement_log.txt

I also attach a white board sketch that indicates each of the measurement configurations.
   (0) [Not shown] The "reference" measurement is identical to the reference setup shown in page 2 of the 2nd attachment in 18518, which is divided out of every transfer function to get rid of the response of the differential driver.
   (1) This is measuring the response of the coil driver as it is typically measured on the bench by CDS. It uses a differential to single-ended receiver and the 40 [ohm] internal load (as I only found out later, the documentation on this box, D1000931 leaves something to be desired), so the response differs from configuration (2) only by a scale factor of 2.
   (2) This is measuring the response of the coil driver as is typically done in the field when the OSEM and/or satellite amplifier is not available. The box (D1100278) is, as far as the coil chain is concerned, only a two 20 [ohm] (for a total of 40 [Ohm]) resistor load.
   (3) This is the "real life" scenario, where we measure the response of the driver with the full SatAmp and OSEM included as a load on the output of the driver. It is in this configuration is where the magic happens, apparently.
