As of COB today, we are on-schedule for the 4 day EX and EY vents. So far no major surprises or issues. Further dust monitor data to be posted later.
As per the schedule:
- The ISI's have been locked on both ETMx and ETMy.
- 2 CC witness samples have been pulled from each BSC9 and BSC10.
- The VE port work has finished at ETMy.
- The TMS work has finished at both stations.
- The ETMx debiasing has been completed (removed ~440 uRad of pitch mechanically at the suspension using the optical lever as the monitor.) Bias is now at zero. This is where commissioners should start looking for beams in a few weeks. Yaw bias remains unchanged (and non-zero).
- Local charge measurements taken on ETMx with in-chamber equipment in prep for discharge procedures.
- ESD feedthru swap has started. Filiberto and Gerardo have pulled the flange and have it out and ready to reterminate with the new connector.
- Quick P and V TFs of ETMx show healthy suspension - Arnaud launched matlab overnight TFs of SUS-ETMx for further check.
First up tomorrow:
- Finish ETMx ESD feedthru work.
- Finish VE port work at ETMy.
- Move equipment to ETMy and Discharge ETMy.
- Close ETMy chamber.
