previous day

1405 Fill LN2 cold trap full.
1410 Plug in all three DCRC boards, noticing a oscillation in Q-outer on all boards, strongest on DCRC55.
Notice that temperature has spiked to 42 mK and begun to settle. The scroll pump was also making loud noises, so the temperature spike could be related to filling the trap, the pump, the boards, or something else?
1415 Zap all SQUIDs.
1425 Commence LHe transfer (14.5%). Temperature plummeted back to base (31 mK) after transfer was started.Oscillations in Q-outer also gone.
1435 Flash on all three dibs to bake overnight.
1505 End LHe transfer (91.9%).
