| 0935 | Tower = 25.6 mK, Still = 0.060 mbar, G1/G2 = 151/141 mbar, 1K Pot = 1.70 K / 32 mbar. MB = 31.2% |
| 0940 | Start takeAndFlash sequence of 1 60-minute data series of Cf data with Frontend Gain = (15/2)/(4/4)/(5/5/5/5), OG = 4/2/4, QET biases = 2V setting from 2017/07/25, with 1000 beginning randoms, 30 sec flash with 30 min wait, and a 15ADC bin threshold trigger on DCRC4pB (Side2pF). Charge biases are DCRC1/2 (Side2/1) = 2/-2 V. |
| 1043 | Fill LN2 cold trap full during flash |
| 1107 | Suspend data taking for short period of DAQ software testing |
| 1115 | Commence LHe transfer (MB=29.1%) |
| 1155 | Cease LHe transfer (MB=92.1%) |
| 1252 | Start takeAndFlash sequence of 2 60-minute data series of Cf data with Frontend Gain = (15/2)/(4/4)/(5/5/5/5), OG = 4/2/4, QET biases = 2V setting from 2017/07/25, with 1000 beginning randoms, 30 sec flash with 30 min wait, and a 15ADC bin threshold trigger on DCRC4pB (Side2pF). Charge biases are DCRC1/2 (Side2/1) = 2/-2 V. |
| 1620 | Fill LN2 cold trap full |
| 1629 | Start takeAndFlash sequence of 8 60-minute data series of Cf data with Frontend Gain = (15/2)/(4/4)/(5/5/5/5), OG = 4/2/4, QET biases = 2V setting from 2017/07/25, with 1000 beginning randoms, 30 sec flash with 30 min wait, and a 15ADC bin threshold trigger on DCRC4pB (Side2pF).
