| 1215 | Fill LN2 cold trap full. |
| 1224 | Tower/MC/Coldplate = 32.7/30.8/187 mK, Still = 1.23 K / 0.110 mbar, G1/G2 = 208/199 mbar, 1K Pot = 1.680 K / 22.0 mbar. Main Bath = 29.1% (predicted level: 29.1%) |
| 1228 | HV = 10.01 V, Vtest = 0.72 mV → Vdetector = 9.72 V |
| 1229 | Dial HV down to zero and short leads. |
| 1230 | Start 30 minute bake with DCRCs 1&2 |
| 1239 | Start LHe transfer (MB = 28.5%) |
| 1313 | Pause transfer, helium cylinder empty, replace. Looks like the dewar is empty too. |
| 1340 | Restart LHe transfer. |
| 1355 | End LHe transfer (MB = 93.4%) |
| 1402 | Dial HV up to 40.04 V. |
| 1412 | Dial HV down to 30.26 V |
| 1422 | HV = 30.26 V, Vtest = 2.44 mV → Vdetector = 29.28 V |
| 1427 | Start 18 1-hour data series (start #6769) of 1-sided 30 V data with Frontend Gain = (15/15/5)/(5/4/4), OG = 4/2, QET biases set with the Ib*pf=30 values in table from May 24, with 1000 beginning randoms, no flashing, and a 24 ADC bin threshold trigger on DCRC1 pA (Side1 pE). |
| 1649 | Attempt relock of DCRC2pC. Sometime after the midpoint of the first series it railed. |
| 1710 | Relock seems to have worked, all six channels show pulses |
