| | 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 → DCRC55(1)/DCRC50(3) |
| | DCRCs powered overnight, zero bias |
| 0920 | Tower/MC/Coldplate = 39.7/31.8/175 mK, Still = 1.15 K / 0.110 mbar, G1/G2 = 144/146 mbar, 1K Pot = 1.52±0.01 K / 7.0±1.0 mbar. MB = 38.6% |
| 0925 | Fill LN2 cold trap bath |
| 1000 | Start IbIs sequence on DCRC1pA, from 700 to 100 step -5 uA, HV = 0 V, front-end gain 10, driver gain 1. |
| 1025 | Start IbIs sequence on DCRC1pB, from 700 to 100 step -5 uA, HV = 0 V, front-end gain 10, driver gain 1. |
| 1052 | Start IbIs sequence on DCRC1pC, from 700 to 100 step -5 uA, HV = 0 V, front-end gain 10, driver gain 1. |
| 1118 | Start IbIs sequence on DCRC3pB, from 700 to 100 step -5 uA, HV = 0 V, front-end gain 10, driver gain 1. This one railed high, need to reset driver offset and redo sequence. |
| 1143 | Start IbIs sequence on DCRC3pC, from 700 to 100 step -5 uA, HV = 0 V, front-end gain 10, driver gain 1. Aborted because DAQ froze. |
| 1214 | sequence seems to be hung up, DAQ web pages unresponsive |
| 1220 | Kill DAQ and restart. Delete files from last sequence. Will now restart sequence. |
| 1222 | Start IbIs sequence on DCRC3pC, from 700 to 100 step -5 uA, HV = 0 V, front-end gain 10, driver gain 1. Seems to be something wrong wtih this data, not sure what, can't process the raw data, files are small |
| 1258 | Start IbIs sequence on DCRC3pB, from 700 to 100 step -5 uA, HV = 0 V, front-end gain 10, driver gain 1. |
| 1326 | Start IbIs sequence on DCRC3pC, from 700 to 100 step -5 uA, HV = 0 V, front-end gain 10, driver gain 1. |
| 1401 | Start IbIs sequence on DCRC3pD, from 700 to 100 step -5 uA, HV = 0 V, front-end gain 10, driver gain 1. |
| 1430 | Constructed a cheater cable to connect a BNC cable to the hi,lo triax connections. This lets us use the Keithley 617 to measure low voltages like the test resistor voltage in the HV board. |
