Previous Day

Setup: DIB1/3/4 → 3.2 MHz filters 3/1/2 → cable 3/1/2 →gender changer 3/1/2 → HVConn 1/3/2 → HV 1/2 → DCRC55/DCRC33
Took 0-volt data overnight, looks pretty good.
1040 Adjust trigger threshold on DCRC1 pA down from 25 to 20.
1043 Start sequence of 24, 1-hour data series of 1-sided 0V HV data with Frontend Gain = (20/20/20)/(-/4/3), OG = 4/2, with 1000 beginning randoms, no flashing, and a 20ADC bin threshold trigger on DCRC1 pA
1204 Tower/MC/Coldplate = 33.0/30.6/191 mK, Still = 1.2 K / 0.110 mbar, G1/G2 = 258/225 mbar, 1K Pot = 1.690 K / 28 mbar, Main bath = 68.1%. Boil off rate: close to slow mode (predicted level: 69.8%)
1210 Fill LN2 cold trap bath LN2 dewar empty.
1327 Fill LN2 cold trap full.
1530 Adjust trigger threshold on DCRC1 pA down from 20 to 15. After this there seem to be some triggers on noise, but pulses are showing up at the right time in the trace so this is probably a good low threshold. Dump sizes increase from about 30M to about 47M. (I wasn't able to check this for three hours, it took that long for the data to show up in the byseries directory.)
