Previous Day

  • Lab in-personnel: Matt, 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)
1045 MC/Coldplate = 28.1/145 mK, Still = 1.09 K / 0.100 mbar / 0 mW, G1/G2 = 131/130 mbar, 1K Pot = 45° / 1.55 K / 8.5±0.5 mbar, MB = 74.3%
1053 Fill LN2 cold trap bath.
1600 Cut shorter two vertical bars of NaI rack that attach to the ceiling of the fridge stand. Raise the back crossbar that these attach about 2 inches higher. This will allow for draping the boron-shield tubes over the detectors. We are working on a design of filling long tubes of fabric with boron powder and draping these over the detector stack.
