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 source behind lead wall on West side of lead/poly shield.
	NaI trigger window: 7.6-11.2 MeV
	Cooled to base two days ago after eleventh 5K pumpout. Taking -83V low-threshold SiHV-triggered PuBe data overnight.
0930	MC base around 29.3 mK. Spikes peaking mostly below 32 mK, some above 37.0 mK.
0930	HV = -91.8 V, Vtest = -21.5 mV, Ileak = -23.6 uA, Vdet = -82.4 V (90%).
1340	MC/Coldplate = 29.4/150 mK, Still = 1.12 K / 0.110 mbar / 0 mW, G1/G2 = 112/101 mbar, 1K Pot = 45° / 1.58 K / 12±1 mbar, MB = 70.0%
1345	Fill LN2 cold trap bath
1705	HV = -91.9 V, Vtest = -21.6 mV, Ileak = -23.7 uA, Vdet = -82.4 V (90%).
