Tues DAY Ops Summary
TITLE: 03/31 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Planned Engineering
INCOMING OPERATOR: None
SHIFT SUMMARY:
Lots of subsystem work going on today. The JAC team continued their alignment work at HAM1. SQZ team continued alignment work at SQZT7 and then in the Control Room. SPI team was in the Optics Lab most of the day.
Tomorrow morning a new HEPA fan will be installed for the h1psl room's anteroom....so it shouldn't affect HAM1 work.
LOG:
- 1411-1500 LVEA technical cleaning (nellie.kim)
- Held off cleaning top of HAM3, since HAM3 was unlocked (they noticed the signs saying so at HAM3), AND bifurcated Laser Safe requires goggles at-height, but that makes it unsafe to see things when climbing on top of a chamber.
