Lab in-personnel: Giulia

Status	Run 76 in progress
Setup	Cables 2/3/1 → diverter/nothing/nothing → Side2-readout HV CONN 1/3/2 → HV 1(L)/2(R) → DCRC50(3)/DCRC55(1), DCRC33(2)→HV control, NaI trigger signal → DCRCX(4) Lead/poly shield fully assembled. Boron-filled socks covering NaI detectors. PuBe behind lead wall on West side of lead/poly shield.
	NaI trigger window: 7.6-11.2 MeV
	Cooled to base yesterday after seventh 5K pumpout. Temperature spikes started at 5:50 am
	Taking -80V data overnight
1039	Start -80.2 V PuBe data series 103 min long, SiHV-triggered, with 1000 initial randoms, 5 Hz in-run randoms, trigger on DCRC1pB threshold 10. Start series with the Start Button
1045	HV = -88 V, Vtest = -17.7 mV, Ileak = -19.4 uA, Vdet = -80.2 V (91%).
1225	Start -80.3 V PuBe data series 531 min long, NaI-triggered, with 1000 initial randoms, 5 Hz in-run randoms, trigger on DCRC4pA threshold 20. Start series with the Start Button
1225	HV = -88 V, Vtest = -17.4 mV, Ileak = -19.1 uA, Vdet = -80.3 V (91%).
1700	MC/Coldplate = 31.3/149 mK, Still = 1.12 K / 0.075 mbar / 0 mW, G1/G2 = 126/129 mbar, 1K Pot = 45° / 1.59 K / 13±1 mbar, MB = 62.6%
1715	Fill LN2 cold trap bath
2125	Start -80.3 V PuBe data series ## min long, SiHV-triggered, with 1000 initial randoms, 5 Hz in-run randoms, trigger on DCRC1pB threshold 10. Start series with the Start Button
2125	HV = -87.9 V, Vtest = -17.4 mV, Ileak = -19.2 uA, Vdet = -80.3 V (91%).
2155	Start -80.3 V PuBe data series 273 min long, NaI-triggered, with 1000 initial randoms, 5 Hz in-run randoms, trigger on DCRC4pA threshold 20. Start series with the Start Button
	DAQ crash of some sort in the early AM. The 07220917_2155 directory has dumps up to 254 (2:13 am). There are more dumps in /midasraw/livedata, up to 272 (2:32 am). So if we can restart lazylogger those should get moved and renamed.
	UPDATE: got the DAQ working again a couple days later, now all 273 raw files are in the proper directory.

Next Day
