0900 DAQ crashed overnight. Collected all -4 V Ba-133 data, but nothing else.
1148 Filled LN2 cold trap.
1200 Start flashing detector.
1500 Stop flashing detector.
1630 Start taking Ba-133 data at -4 V, using 40 ADC bins trigger threshold.
1730 HV DCRC interface board wired up. Conduct electrical check: grounding good; and everything else looks fine:
Ebox Pin Resistor Resistance from pin to R38 input [MΩ] DCRC Pin Continuity?

1845 Stop data run. Three data series collected.
1900 Start helium transfer. Helium liquid level 10.0%.
1905 Start flashing detector.
1940 Stop flashing detector.
1945 End LHe transfer (92%)
1950 Stop helium transfer. Helium liquid level 92.0%.
2039 Started data taking at -10V, 40 ADC bins, 120 min series (no Ba-133) source.
Checked out the safety DCRC interface board. Looks good.
2045 Filled LN2 cold trap.
