0240 Start data acquistion, triggering on charge channels with 0.1 ms trigger delay and 0.4096 ms trace length. OR charge trigger threshold 40 ADC bins for all charge channels, and coincidence time set to 10 μs. Flash for one hour, followed by cool down for 2 hours. Then take ten 5-minute data series each at -/+1.5 V & +/-1.5 V biases. Flash all LEDs for 6 seconds between data series with usual settings, and wait 20 minutes for cryostat to cool. Finish with a 20 minute flash and 2-hour cool down.
Phonon pulses in test data series look fine. Trigger rate is around 9 Hz.
0530 Take advantage of detector flash and cool down to fill N2 cold trap full.
1015 No data being taken, filled LN2 cold trap full.
1018 Fed Cricket 3 pellets.
