I took us to comissioning and to NLN_CAL_MEAS for a calibration measurement as requested by Louis. I ran the command: "pydarm measure --run-headless bb sens pcal", I started the measurement at gpstime 1373514290, at finished at 1373516180 a bit longer than I was expecting. The calibration monitor from before I started.

TITLE: 07/16 Eve Shift: 23:00-07:00 UTC (16:00-00:00 PST), all times posted in UTC
STATE of H1: Observing at 133Mpc
SHIFT SUMMARY:

• We've been locked for 9:55 as of 07:00UTC
• Calibration measurement taken
• Handing off to Corey, as he walked in we got hit by a 7.3 from Alaska and lost lock

I went out of Observing at 03:44 to take a broadband measurement (alog 71361) after seeing LLO was down and checking in with their control room via TS. I after it was done I put everything back and brought us back to Observing at 04:20UTC. I accidentally took a longer measurement than I intended to, I had extra unneeded arguments (sens pcal).

LOG:

No log for this shift

We've been locked and Observing for 5:52, everything looks good

QUICK SUMMARY:

• Taking over from Camilla
• We've been locked and Observing for 1:54
• CDS/Vac/Dust/Violins look good

Eleonora, Camilla

We repeated Eleonora's 68910 OFI shaking with longitudinal OMC shaking 20:14UTC-21:01UTC while we were waiting in OMC_WHITENING for the violins to damp. This means we were not in our full nominal low noise configuration.

Injected a 0.65Hz (Rahul's TF's in 69726) sine wave into H1:SUS-OMC_M1_TEST_L_EXC using 'awggui' command. Gain 3000. This could be seen as +/- 6um on DAMP_L_INMON, with some cross-coupling in other degrees of freedom, see attached. 

• 20:14- 20:18UTC ramping up gain to get good sized shelf.
• 20:18 - 20:29UTC 0.65Hz with G 3000 - with SQZ
• 20:29 - 20:39UTC No shaking, quiet time - with SQZ
• 20:40 - 20:50UTC No shaking, quiet time - No SQZ
• 20:51 - 21:01UTC 0.65Hz with G 3000 - No SQZ (no difference)

This was more data than the 10 minutes Eleonora asked for but I had the time while the violins were damping. She would like this repeated for OPO and FC but I wasn't sure how the FC and IFO SQZ ASC's would react so will need to speak with Naoki first.

Noticed that the arm power in the TCS simulation model were way low. I increased the x-arm (H1:TCS-SIM_XARM_POWER_WATTS_PER_INPUT_UNIT) and y-arm (H1:TCS-SIM_YARM_POWER_WATTS_PER_INPUT_UNIT) calibration factors from 4.32 to 7.21 and from 4.09 to 6.62, respectively.

The simulation isn't useful yet, since it assume central CO2 heating.

1373483210 After 18h29 in NLN. No obvious reason why.

STATE of H1: Observing at 134Mpc. IFO has been locked for 18h24

SHIFT SUMMARY:

H1 & L1 were up the entire shift (so I did not get a chance to run the quick broadband calibration measurement---a good problem to have with such well-behaved instruments!).   Passed this info on to Camilla in case she gets a chance to run the short measurement (i.e. "pydarm measure --run-headless bb"

Oh, and it's almost 80degF outside!!!!
LOG:

• 1034 & 1044: Brief INVALID/NOT_CONNECTED_ERROR alarm for DUST Alarm Handler (pop-up roughly states:  "Channel Access Exception:  Virtual circuit unresponsive  Context:  h0epics.cds.ligo-wa.caltech.edu [xxxxx]").  This would briefly show up on the CDS Overview as an H1EDC RED dot due to channel drops.
• 10:56:09 Big broadband glitch w/ EX & DCPD saturations on Verbal w/ range drop to about 13Mpc.

Corey notes if LLO goes down we should run the pydarm measure --run-headless bb command following the Taking Calibration Measurements Wiki

Smooth sailing for H1 (& L1) with summer twilight skies & outside temp of 71degF.  Just had a huge glitch a couple minutes ago, but no biggie.

DIAG_MAIN flashes the messages PSL ISS difracted power is low every few minutes, this is known and will be fixed soon by Jason

Back into NLN at 0:34UTC in Observing at 00:44UTC, LLO was relocking around the time so Robert went out to do some PEM scatter work in the LVEA while we waited for them to get back and we damped violins.

WP11290 Revert LALAPPS to fix memory leak

Erik, Dave:

At 13:21 PDT Erik restarted the psinject CW process on h1hwinj1 after downgrading the libSIStr,so library file. This has fixed the memory leak h1hwinj1 has had since its upgrade when tconvert was replaced by gpstime.

Between 13:21 and 14:48 there has been no additional memory allocated, before memory was used at a rate of 3.5MB/min.

We will run with this over the weekend and if it all looks good I will revert the h1calinj SDF change make to permit INJ_CW GAIN and TRAMP changes while in observation (WP11304)

6 hour trent of INJ_CW with restart shown in attachment.
