Previous Day

Setup: DIB1/3/4 → SL 27/19/20 → 3.2 MHz filters → cables 2,1,3 → HV board inputs 1,3,2 → HV board outputs 1,2 → DCRC55(1)/50(3). Also DCRC4 is powered and hooked up to control the HV setting.
0850 Restart MIDAS.
1621 Tower/MC/Coldplate = 24.2/25.9/155 mK, Still = 1.2 K / 0.110 mbar, G1/G2 = 221/199 mbar, 1K Pot = 1.65 K / 38 mbar, MB = 59.9%
1623 Fill LN2 cold trap full.
1628 Begin IbIs data sequence on DCRC3pB with HV=0V from 750 to 300 uA in -1.0 uA steps, 3 seconds of data per step. (IbIsDCRC3pB.msl)
sequence finished but we forgot to start the DAQ programs, so need to redo it.
2405 Restart MIDAS, then start DAQ programs
2406 Begin IbIs data sequence on DCRC3pB with HV=0V from 750 to 300 uA in -1.0 uA steps, 3 seconds of data per step. (IbIsDCRC3pB.msl)
files are unusually small, 383 K. hmm… they seem to have no data in them.
2425 DAQ programs wouldn't stay on. Restart MIDAS again. Then restart DAQ programs.
2435 DAQ programs won't stay on. Giving up. I assume we'll need to powercycle the DCRCs.
