Today's activities:
- HAM7 pumpdown status: ~9.7E-7 Torr
- Corner pumpdown: HAM6 turbo was switched on, and valved in; it helps a lot - as anticipated - especially with the semi-isolated HAM6 volume. The pressure is ~1.1E-6 Torr, ~26 hours after the HV pumping started
- EX pumpdown status: 3.1E-8 Torr: the post-vent RGA scan is ready; the results show that the chamber is OK - compared with past RGAs. Another bakeout is necessary, see details here: https://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=75918. The GV will remain closed during FAC works (1-2 weeks)
- HAM8 works: the chamber closing and pumping is now postponed to early-next week
