Today's activities:
- The corner (BSC8 blanks and 1000 amu RGA GV) was leak checked, and everything was found OK - this is a big relief, as this was not anticipated - see https://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=75717
- After this, the Kobelco is now shut off: https://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=75980
- HAM7 pumpdown status: ~5.9E-7 Torr
- Corner pumpdown: ~4.4E-7 Torr, ~147 hours after the HV pumping started
- EX pumpdown status: 2.6E-8 Torr. The GV will remain closed during FAC works (during this week)
- At the EX RGA the bakeout temperature has been ramped up to 200 deg C
- There was an issue with the RGA connections, which has been resolved in the afternoon. Tomorrow RGA scans and possibly bakeouts will be done at the HAM7 and the OMC RGAs
- A pumping cart was connected to the GV2 annulus system, and its all-metal valve has been opened. Now it is being pumped with the cart in parallel with the AIP
- The relay tube was valved in to HAM7 (RV2 is open now)
