Vertex volume ready pump down
Bubba, Gerardo, Kyle We removed BSC1's North Door for Betsy W. and re-installed after she completed her in-chamber work. We are pumping BSC1's annulus with a small turbo backed by a leak detector overnight. We expect to helium leak test the door in the morning followed by submission of a WP to pump down the Vertex Volume.
Torqued the two flanges that were removed, F2-3 and F3-1. Leak testing needs to be done for both.
