Ops Day Shift Summary
TITLE: 05/22 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Planned Engineering
INCOMING OPERATOR: None
SHIFT SUMMARY: Another busy day! After some pumpdown troubleshooting this morning, ISCT1 was rolled back into place, its bellows were attached, and beam alignment on the table is ongoing. Cycled ISC_LOCK through DOWN and SDF_REVERT, but ran into an issue where ETM ESD chassis needed to be restarted after the power outage last night. I also ran a quick rotation stage calibration.
- Sensor correction is ON
- All chambers are back to their nominal configurations except HAM1, which still needs work done on the ISI's isolation loops
- IMC is LOCKED with 2.2W input (rotation stage still needs to be calibrated)
- ISC_LOCK in READY
