Previous Day

Current setup: iZIP mode, DIB1/2/3 → cables → 3.2 MHz filters → DCRC55/33/50.
Overnight: Taking Ba-133 data. Tower temp looks fine.
0935 Put Ba source back in safe. Fill cold trap full.
1005 Set phonon thresholds back to Wednesday's values:
A B C D
DIB1 36 40 42 40
DIB2 24 18 20 28
DIB3 40 46 58 48
1009 Start 1 cycle of 30min runs of background data at +/-1V, -/+1V, +/-3V, -/+3V, FG=5/2/5, OG=3, 1000 initial randoms, 2000 events/file, 30s flash and 25min cooldown after.
1530 Start 2000 randoms of 20ms trace length background data at 0V, 400uA QET bias, FG=5/2/5, OG=0/1/0, 2000 events/file.
1533 Quit data series because I accidentally set the run length to 3min.
1542 Start using MultiDAQ instead of DAQDAQ for this, so that we don't have to specify a run length. Start a series with same settings but stop it immediately because I didn't specify a trigger file.
1544 Start 2000 randoms of 20ms trace length background data at 0V, 400uA QET bias, FG=5/2/5, OG=0/1/0, 2000 events/file. Event rate of ~1.2Hz.
1553 Rate has dropped to ~0.3Hz. Set DIB1 (DCRC55) pA's trigger threshold to 3 ADC bins. Rate immediately increases to ~4Hz. It shouldn't matter since it's random, but… ya know…
1633 LabVIEW crashed after copying the data dumps to Chokula, so reboot LabVIEW for overnight data.
1645 Restart LabVIEW and reset phonon threshold values to Wednesday's (above).
1657 Place Cf source inside shield near detector for overnight CF data.
1702 Start 5 cycles of 30min runs of Cf data at -/+4V, +/-2V, +/-4V, FG=5/2/5, OG=3, 1000 initial randoms, 2000 events/file, 30s flash and 25min cooldown after.
1714 Fill LN2 cold trap full.
Main bath: 50.8%.
