| 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. |
| DCRCs off. | |
| 1030 | MC/Coldplate = 30.5/161 mK, Still = 1.06 K / 0.090 mbar / 0 mW, G1/G2 = 115/116 mbar, 1K Pot = 45° / 1.51 K / 7.0±0.5 mbar, MB = 71.8% |
| 1042 | Fill LN2 cold trap bath |
| 1325 | Turn of DAQ programs. I want to disconnect the DCRCs because I can't read any resistances in the connectors for the motor coils, they all seem open - need to troubleshoot. |
| 1335 | Power down DCRCs 1&3. Disconnect Cable 2 from diverter and plug into breakout box. Use the checkout spreadsheet from March to check which connections are the motor coils. All read open! Check to make sure this is the right cable - Cable 2 should connect not only the motor but also the only LEDs. One of the LEDs reads standard voltage. (Fridge warmed up when I tested it with the multimeter as if it had been flashed.) So seems like the right cable… |
