Previous Day

status: Warming up. Both LN2 traps have been pumped to dump. Mixture in dump. 1K Pot needle valve open. MC and Still heaters on both @ 20 mW.
0930 Tower/MC(Cernox)/Sorb = 24.9/24.6/49.5 K.
1200 MC(Cernox)/Sorb = 25.2/52.9 K.
1220 Around this time, the MC temperature started rising more quickly. Also I've been monitoring the helium recovery rate from the bath, and around this time the rate slows down drastically. Probably this is where the bath has completely boiled off.
1400 MC(Cernox)/Sorb = 25.9/52.9 K.
1600 MC(Cernox)/Sorb = 28.5/73.2 K.
1700 MC(Cernox)/Sorb = 30.3/80.9 K.
1700 Turn off MC and Still heaters.
1945 MC(Cernox)/Sorb = 43.7/108.4 K.
