Today's activities: - The HAM5/HAM6 annulus system pumpdown continues. The Turbo backing line is already at around ~1E-5 Torr - The pumpdown of the corner has continued. The pressure as of this writing is 9E-1 Torr, which indicates that the Turbos can be switched on tomorrow. A pressure update will be in the comments, when the roughing pumps will be stopped for today - The pumpdown of HAM7 and the relay tube continues. HAM7 will catch up with the relay tube tomorrow, and so those 2 volumes will be valved together - The mobile cleanroom in the FCT was pushed above C-4 position, as a gauge will be added there shortly - see pic. - The instrument air system will be bypassed with the Kobelco compressor, as the inst. air compressor keeps failing (for more detail see aLog: https://alog.ligo-wa.caltech.edu/aLOG/index.php?callRep=79503)
