- Lab in-personnel: Giulia, Zach
| 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. NaI trigger window -t10760 -T15760 (7.6-11.2 MeV) |
| Taking 0V NaI-triggered data continuously | |
| 1020 | MC/Coldplate = 29.1/155 mK, Still = 1.13 K / 0.110 mbar / 0 mW, G1/G2 = 116/112 mbar, 1K Pot = 60° / 1.54 K / 7.0±0.5 mbar, MB = 44.0% |
| 1025 | Begin filling LN2 cold trap bath |
| 1310 | Move PuBe to north side of fridge, run scanrate on NaI |
| 1415 | Being PuBe to 4th floor lab, set up Na22 on string so that it is next to NaI detector 19 (around 113 cm below the top of detector 1), run scanrate |
| 1440 | Begin LHe transfer @ MB = 38.2% |
| 1522 | Ended LHe transfer @ MB = 91.5% |
| 1550 | Put away Na22 and bring back PuBe |
