| | overnight: Tower temp rose from 37 mK to 40 mK during transfer yesterday. Has stayed around 40.6 mK since then with a few small transient spikes of 0.5-1 mK. 1K pot has been stable at 1.45 K / 4.0 mbar |
| 1013 | Tower/MC/Coldplate = 40.6/40.4/184 mK, Still = 1.10 K / 0.055 mbar, G1/G2 = 252/232 mbar, 1K Pot = 1.45 K / 4.0 mbar. MB = 69.6% |
| 1018 | Fill LN2 cold trap full. |
| 1032 | Let's try and start up the DCRCs. Restart MIDAS. Power on DCRCs. Tower briefly spikes to 180 mK then starts to settle. |
| 1044 | Tower = 44.6 mK and slowly falling. Start DCRC programs. Start Pulse Viewer. Can see pulses on all channels except DCRC1PB. Its offset is staying out of range of the driver offset. |
| 1050 | Tower = 44.0 mK |
| 1052 | Start 119-minute background data series at HV = 0V, Driver Gains = 2x, QET biases = (290/270/315)/(140/315/310) uA, Front-End Gains = 10, 1000 initial randoms, trigger on DCRC3pB/C/D threshold = 16/70/50 |
| 1251 | Starting at 1115, Tower started rising, now at 94 mK. Stop the run and turn off DCRCs. |
| 1308 | Tower = 88.5 mK and falling. |
| 1423 | Tower = 43.8 mK and still settling. Power DCRCs again. Tower spikes to 180 mK and falls back to 43 mK over 30 min. |
| 1504 | Start 7-minute SC noise data series at HV = 0V, Driver Gains = 2x, QET biases = (0/0/0)/(0/0/0) uA, Front-End Gains = 10, 1000 initial randoms, 5 Hz randoms |
| 1512 | Tower = 45.5 mK and rising, stop data series. |
| 1524 | Tower = 49.5 mK and rising, stop DCRC programs. |
| 1532 | Tower = 55.2 mK and rising, power down DCRCs. |
| 1630 | Tower = 44.7 mK and cooling. |
| 1631 | Fill LN2 cold trap full. |
