TITLE: 9/12 EVE Shift: 23:00-7:00UTC (16:00-0:00PDT), all times posted in UTC
STATE OF H1: Has been fairly steady at 70Mpc with a few glitches & locked for all but 40min of the shift.
SUPPORT: Evan & Jenne were here fairlyl late
DAY'S ACTIVITIES:
-
23:00 H1 still recovering from noisy New Zealand quake. Below are attempts during my shift
-
Dropped out at various points (Jenne tried a few tricks to help us ride the seismic: offloading SRM Length signal from M3 to M1 & Boost for DHard Yaw)
-
Had one lockloss due to engaging the 2nd Loop for ISS (& Commissioners grumbled)
-
On about the 3rd attempt H1 finally made it up (and this was without any of Jenne's tricks).
-
23:23 NOMINAL_LOW_NOISE
-
23:25 LSC SDF diff was changed to Not Monitored (H1:LSC-PRCL_TRAMP [5.0setpoint, & 2.0epicsvalue])
-
0:23 Stefan took ifo to Undisturbed
-
0:27 Back to Commissioning for Evan Noise Budget Injections
-
2:25 Evan noticed IMC-F oscillations (~30sec period) on the Tidal striptool. We didn't see any other oscillations/seismic noise. He mentioned this occurred during Jeff's shift recently, too.
-
3:08 Observation Mode for H1* (this segment has OMC REFL Beam Diverter Open; this was not noticed by SDF...is it Beckhoff? This was for OMC jitter test.)
-
3:53 GRB Verbal Alarm
-
4:55 L1 at Low_Noise, but not Observation so, Dropped Out of Observation Mode to:
-
Close OMC Refl Beam Diverter (ETMy saturation around this time)
-
Allow Peter Shawhan to restart Continuous Wave Injections, but he was unsuccessful
-
5:00 Back to Observation Mode
-
5:26 Critical Alarm for H0:FMC-EX_CY_H2O_SUP_DEGF

6:58 Handing off to Cheryl
Restart CW postponed till tomorrow due to GRB. Will restart Burst Injection "schedule", but it will not be active during GRB stand down time.
