| 1415 | Commence data acquisition. Start flashing for 1 minute followed by cooldown for 20 minutes. Each grounding test set will consist of one 5-minute data series, interspersed by 6 seconds of flashing and 20 minutes of cooldown. Trace length 3.2768 ms, 400 μs delay, 2k events per file. Data acquired for following biases in order: no changes made to ground, isolate system from IVC pump, remove dewar metal cords. For each set 0 V; & 0 V. DIB3 kept at 0 V. Phonon OR trigger thresholds set at 25 ADC bins for all phonon channels, except DIB3 which has triggers thresholds of 25 ADC for all channels except channel D, which has threshold of 40 ADC. Ba-133 source mounted on dewar. |
