HAM8 +Y Door Installation

(Randy T., Jordan V., Travis S., Janos C., Gerardo M.)

The HAM8 +Y door is on.  One known issue with this door was the inner O-ring, it had scuff marks from about 6:30 all the way up to 10 o'clock.  The O-ring was replaced with a new one.  No other issues were noted during the installation of the door.

The 2 blanks were installed on the two access ports, these conflats need to be leak tested in the coming days.

Annulus system is pumping down and will continue to pump with an aux cart until the ion pump can take over.

Roughing was started, chamber volume is currently at ~500 torr, roughing was stopped and will restart tomorrow morning.
