1945 Commence LHe transfer (30.7%).
2027 Finished LHe transfer (95.2%).
2030 Start flashing detector for 8 hours followed by 2 hour cooldown and data acquisition. Each bias set will consist of four 10-minute data series, interspersed by 6 seconds of flashing and 20 minutes of cooldown. 3.2768 ms trace length; 400 us delay; 200 uS coincidence time; 10K events per file. Data acquired for following biases in order: 0V DCRC33 (DIB1), 0V DCRC31 (DIB2); +4 V DCRC33, -4 V DCRC31; -4 V DCRC33, +4 V DCRC31. Phonon OR trigger thresholds set at 25 ADC for all phonon channels on each DIB.
