0949 Stop flashing detector. Temperature was at 165 mK.
1005 Filled LN2 cold trap.
Fed Cricket 4 pellets.
1039 DCRC33 reads 0000. Considering that the detector was flashed properly, I am inclined to believe that it was still powered during that time. Its light is still on, as well, despite reading 0000. I wonder if this was associated with stopping the flashing?
Terminal for DCRC33 did not disappear, though. This is consistent with previous behavior a couple of days ago.
Power available is 95 W. Charge channels look bad. Re-powering board and FET heater now.
1344 Finished charge breakdown studies for + V Qi, 0 V Qo on Side 1 with side 2 grounded. Increased Qi up to 13 V but no significant sign of charge breakdown between Qi and Qo. Quickly flashed detector.
1414 DCRC32 reads 0000, though the light is on. Terminal did not disappear. This might have occurred after I stopped flashing the detector.
1620 Finished charge breakdown study for 0 V Qi, + V Qo on Side 1 with side 2 grounded. Increased Qo up to 13 V but no significant sign of charge breakdown between Qi and Qo. Quickly flashed detector.
DCRC32 reads 0000 again.
1845 Begin LHe Transfer (28.3%)
1944 End LHe transfer (90.9%).
Fed Cricket 4 pellets.
