Previous Day

  • Lab in-personnel: Matt, 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)
1215 MC/Coldplate = 28.3/145 mK, Still = 1.08 K / 0.100 mbar / 0 mW, G1/G2 = 100.6/101 mbar, 1K Pot = 18° / 1.55 K / 8.0±0.5 mbar, MB = 69.9%
1220 Fill LN2 cold trap bath
1320 Install lead on South wall of lead-poly shield (the side with the NaI array). There's a gap on the right side to accommodate the cables from the array. Zach minimized this gap by choosing a combination of wide and narrow lead panels. The gap is about 6cm wide.
