Logentry Text:
The Buffer Dewar is at 56% helium level and the setpoint is 60 so it is nearly  full.
The Torus is oscillating its level around setpoint. I noticed that the supply flow valve at ESR is cycling at the same frequency.

The Solenoid Lead reservior is full and steady and the Magnet reservoir is filling and currently  at 35 with a setpoint of 70%. 

The indicated flow rate to the Hall  is Averaging aboout 15g/s and should back off when the helium levels are satisfied, and I expect that the 4K supply valve will stop throttling.
