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)/DCRC55(1) DCRC33(2) → 1kV power supply → HV input Three walls of the lead/poly shield are up.
	Status: Taking data.
1153	Tower/MC/Coldplate = 39.0/30.2/199 mK Still = 1.3K/ 0.10 mbar / 0 mW, G1/G2= 109/103 mbar, 1K Pot = 1.7 K / 80 mbar. MB= 21.7%
1158	Fill LN2 cold trap bath.
1200	Jiajin is frozen following IT maintenance period. Can't even ssh to it. Power cycle jiajin.
1212	Commence LHe transfer. MB=21.7%
1215	1K Pot pressure is again unstable during the transfer. Ran off scale initially, now oscillating around 600 mbar.
1248	Cease LHe transfer. MB=75.9% :(

Can start to make decent looking spectra with all this data. This uses inner events and a balanced PsumOF, with a little extra emphasis on PF. We're definitely seeing the Ge M-shell line now.

1300	Start a sequence of 8 @ 50 min series at HV = 180→306V, rate 2.49V/min, with 10% prebias for 2 minutes, flash at end with 30 min wait. CDMS detector: Driver Gains = 1x, DCRC4/1 QET biases = (490/400/495)/(420/480/450) uA, Front-End Gains = (2/2/3)/(5/5/5) 1000 BOR, 5Hz InRun randoms, trigger on DCRC1pD threshold = 6, baseline/sample length = 120/28 (standard 16/5), phonon pre-pulse 500 (standard is 500). Use sequence HVdrift_8X180V_2p49VPM_loopversion_prebias_10_2_dur_50min_flashDCRC_1_4.msl
