| Setup | DIB1/3/4 → 3.2 MHz filters 2/3/1 → cable 3/1/2 → gender changer ?/3/2 → HVConn 1/3/2 → HV 1/2 → DCRCX(4)/DCRC55(1) DCRC33(2) → 1kV power supply → HV input Two walls of the lead/poly shield are up. |
|---|---|
| 0840 | Adjust DCRC4pB driver offset to unrail it |
| 0846 | Start a 75 min series at HV = 200→400V, rate +2.64V/min with 10% prebias for 2 minutes, flash at end with 30 min wait. CDMS detector: Driver Gains = 1x, DCRC4/1 QET biases = (420/400/440)/(420/400/450) uA, Front-End Gains = (2/2/3)/(5/5/5) 1000 BOR and 1000 EOR randoms, trigger on DCRC1pB/C/D threshold = 6/6/6. Use sequence HVdrift_200V_2p64VPM_prebias_10_2_dur_75min_flashDCRC_1_4.msl |

| 1235 | Tower/MC/Coldplate = 43.5/32.0/167 mK, Still = 1.01 K / 0.090 mbar, G1/G2 = 160/149 mbar, 1K Pot = 1.63 K / 22 mbar. MB = 66.5% |
| 1240 | Fill LN2 Cold trap bath |
