We are pumping down with RP1 & RP3 oily roughing pumps at 3 Torr/min speed. The butterfly valve was just removed.
The PSL shutter is open to vacuum at ~100 mW 1064 nm. The inter lock should close it at ~5 mTorr.
Rana will shut down pumping tonight.
He will close V3 from screen, close RV1 valve with torque wheel, turn off roughing pumps and disconnect hose between RV1 and roughing pumps.
I will restart pumping early morning tomorrow.
