Tuesday Maintance Ops Shift Start
TITLE: 09/17 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Lock Acquisition
OUTGOING OPERATOR: Ibrahim
CURRENT ENVIRONMENT:
SEI_ENV state: CALM
Wind: 3mph Gusts, 2mph 3min avg
Primary useism: 0.01 μm/s
Secondary useism: 0.08 μm/s
QUICK SUMMARY:
H1 is locked for over 5 hours but not observing. Looks like we were taken out of Observing at 7am.
Most Likely because it's running the Magnetic injections.
Inlock charge measurements are next.
Work to be done today:
CDS - [ISC, SUS] EX - Swap the SUS signals from the 18 and 20 bit 8ch DAC's over to the LIGO 32 bit 32ch DAC at SUS-EX. (Marc, Fil, Daniel) WP 12079Access Laser LVEA TCS table tour (Camilla, TJ?) WP12080TCS - 8a to 8:15a [LVEA HWST] Reinstall Hartmann Sensor Masks On TCSHT4R HWS Table (Camilla)VAC- [CP1 (Y Arm) / CP2 (X Arm)] Outside Work -- Radiator (or vaporizer) examination. (Gerardo, Travis, Jordan) WP12083 -- postponed
VAC- [CE/MR] Power down the ion pump controller, to then move the controller within the rack, and connect new signal cables. (Jordan, Travis, Gerardo) WP12085New Guardian node TEST_NOTIFY. (TJ) WP12091SEI - [EX] Recenter BRSX. Turn on picomotor, adjust BRSX adjustment mass. (Jim) WP12088CDS- [PEM] Verify cabling for PEM sensors in the FCES. New cabling for Ham floor and beamtube accelerometers will be installed. (Fil, Dave) WP120898a SQZ: SQZT0 Realign PUMP AOM --Postponed
SQZ: [With IFO, Nominal Low Noise] Go to 0V psams with locked IFO turn off PSAMs driver (during IFO thermalization time). -- postponed
