Previous Day

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 → DCRC55(1)/DCRC50(3)

1.1kV → NaI B/C → Ortec 452(gain=5, shaping = 6 us, output=10V) / Ortec 575A(gain=10, shaping = 3us) → DCRCX(4)
DCRC33(2) → kepco 1kV power supply → HV input
status: Took SiHV+NaI background data overnight.
1445 Tower/MC/Coldplate = 31.1/-/- mK, Still = 1.4±0.1 K / 0.075 mbar, G1/G2 = 138/128 mbar, 1K Pot = 1.62 K / 24 mbar, Turbo on IVC = 1.0 nbar, MB = 63.2%
didn't bother to record MC and Coldplate temperatures because a flash just happened.
1450 Fill LN2 cold trap bath.
2028 Start 10 x 2hr 40 V background datasets each split into 10min subruns, with CDMS and NaI detectors running and DCRC2 as HV controller. Using sequence HVscan-40×10-15_5PreBias-30Flash 30wait-2hrData-10minSubRun.msl
CDMS detector: Driver Gains = 2x, QET biases = (280/260/305)/(140/280/295) uA, Front-End Gains = 10
NaI detector: 1.1kV → NaI B/C → Ortec 452(gain=5, shaping = 6 us, output=10V, Pos) / Ortec 575A(gain=10, shaping = 3us, Pos) → x10/x10 attenuator → DCRC4PB/PA, Driver Gains = 1/1, PhononWaveFormLength = 1024 (512 samples), PhononPrepulseSamples = 64 (64 samples)
1000 BOR randoms, trigger on DCRC3pB/D threshold = 7/9
we'll probably stop this sequence early, before the Sunday transfer. Update: Indeed stopped early giving us 6 x 2hr series.
