TITLE: 06/07 Eve Shift: 2300-0800 UTC (1600-0100 PST), all times posted in UTC
STATE of H1: Commissioning
INCOMING OPERATOR: TJ (in name only)
SHIFT SUMMARY:
IFO is in DOWN and staying that way until tomorrow.
The remainder of the H1 EVE Shift and the entirety of the upcoming OWL Shift have been cancelled due to Locking issues with the new OFI configuration.
We have not been able to lock since yesterday's short 2.5 hr lock, ending at roughly 10:30 UTC.
Comissioners were tirelessly testing out a new OFI spot configuration when my shift started and despite their determination, it does not seem to be in a good spot. Jenne and I confirmed that IFO_OUT suspensions do not saturate during powerup but it seems that they tend to do so (only OM2 and OMC) at LASER_NOISE_SUPPRESSION. Thus, we have elected to revert the changes tomorrow morning. Check out alog 78290 for more information on this comissioning work.
