Corner station pumpdown paused for the night
The roughing scroll pumps were valved out and shut down for overnight. Pressure in the corner was ~2 Torr at the break.
Travis continued with the pumpdown, the corner was restarted on Tuesday morning, and the pumps ran for the entire shift for the corner, HAM1 was delayed by technical issues that got resolved slowly, then the pumpdown started or restarted. Main issue was a not so alive gauge, and a disconnected gauge. Both were resolved.
Pumpdown was stopped at the end of the shift.
