| | overnight: took 2/-2 V data triggering on a phonon channel. Last flash was at 04:42. Last data series began at 05:10. The sequence ends with grounding the detector but does not do a final flash, so the detector probably needs to be flashed again. Data looks good. |

| 1631 | Start sequence 12 30-minute data series of charge-bias-scan 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) = +/-. Side 2 biases in order are 0, 0.25, 0.5, 0.75, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5 |
