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 thirteenth 5K pumpout.
1350	MC base 29.7 mK, most spikes peaking below 35 mK, some above 40 mK
1355	MC/Coldplate = 29.7/150 mK, Still = 1.12 K / 0.110 mbar / 0 mW, G1/G2 = 126/131 mbar, 1K Pot = 45° / 1.59 K / 11±1 mbar, MB = 68.7%
1400	Fill LN2 cold trap bath
	Tracking phonon baselines as helium films build up:

	By 20:20 it looked like the pulses had already gotten weaker, with baselines elevated by a little over 15 mV. The first noticeable signs in MC temperature occurred at around 18:00: baseline temperature rose from 29.8 to 30.2 mK, then fell a bit over the next hour, rising again between 19:45 and 20:15.
