Logentry Text:
The Torus magnet is at 100% (normal) and the Buffer dewar is at 65% (normal) helium levels,
The Solenoid Lead reservoir is at 100% (normal) helium level. And with these, all cryogenic loads are on cold return.
The Solenoid magnet coils are cooling at 5K/hr and this will increase and the average coil temperature is 27K so the magnet reservoir should be full in 3-5 hrs.

Probir is working on what tripped the magnets. It appears that the Torus tripped first on an interlock that may have a "glitch"
