Began rough pumping of X-end using the QDP80. Also, began pumping BSC9's annulus volume via locally connected small turbo backed by an aux. pump cart. -> The 10" gate valve at the inlet of the Main Turbo Pump will be closed before leaving tonight. Pumping to resume tomorrow (a.k.a. attended pumping).
Valved out QDP80 at EX for the evening (closed 10" GV & right angle o-ring valve). Pressure is at 1.5 Torr after six hours of pumping. Will resume pumping tomorrow morning.
