Bob and Steve closed BS chamber with the help of the manual Genie lift and the pump down started. The PSL shutter was closed and manual block was placed in the beam path. High voltage power supplies were checked to be off.
Pumping speed ~ 1 Torr/min was achieved at 1/8 of a turn opened roughing valve RV1 |
