| Setup | DIB1/3/4 → 3.2 MHz filters 2/3/1 → cable 3/1/2 → gender changer 3/?/2 → HVConn 1/3/2 → HV 1/2 → DCRCX(4)/DCRC50(3) DCRC33(2) → 1kV power supply → HV input Lead poly shield is erected, N/E/W walls complete, no poly or lead on S wall. |

| 1344 | Tower/MC/Coldplate = 39.8/29.9/188 mK, Still = 1.63±0.15 K / 0.150 mbar, G1/G2 = 276/248 mbar, 1K Pot = 1.79 K / 13 mbar. MB = 30.2% |
| 1354 | Start LHe transfer, MB=30.2% |
| 1407 | Fill LN2 cold trap full. |
| 1430 | Cease LHe transfer, MB 92.5% |
| 1554 | Start a background series at HV = 300→400V @ 3.9 V/min (26 min duration) with 1 minute 15% prebias CDMS detector: Driver Gains = 1x, DCRC4/3 QET biases = (430/410/500)/(500/460/420) uA, Front-End Gains = (2/2/3)/(5/5/5) 1000 BOR randoms, trigger on DCRC4pA/B/C threshold = 7/6/6 use sequence looptest_HVdrift_fast_300V_3p9VPM_prebias_15_1_dur_26min.msl |
| 1655 | Sequence completed but files aren't being copied to /byseries. Not sure why because LazyLogger seems to be running. |
| 1705 | Kill and restart MIDAS. Looks like lazylogger is moving files. |
