- 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 W side of fridge. NaI array trigger window = 4.73 - 5.13 MeV |
| Cooled to base yesterday after twenty-seventh 5K pumpout. Temperature spikes began at 1:35 am. | |
| 1545 | Fill LN2 cold trap bath |
| 1600 | MC/Coldplate = 30.7/150 mK, Still = 0.98 K / 0.060 mbar / 0 mW, G1/G2 = 104/105 mbar, 1K Pot = 60° / 1.58 K / 9.5±1.0 mbar, MB = 61.7% |
| 1605 | Plugged in DCRCs 1&3 |
