Logentry Text:
Hall B Torus average temp is 55K and the Solenoid is at 25K.
I contacted Johnathan and asked him to close EV6721B to force us into warm return.
He did that at 07:58 and now we can start to recover the cryogenics.
Denny is looking at the upper turbo pump for the Torus, the lower one (on the torus vacuum space) is running and pumping on the vacuum space, so is the roots pump.
