| 2040 | Remove Ba-133 source. Start flashing detector for 5 hours followed by 2 hour cooldown and data acquisition. Each bias set will consist of 5-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; 500 events per file. Data acquired for biases listed in table in order given with Qi DIB 3 threshold of 1 ADC bin in effort to induce random triggers. Trigger rate poor at 1-2 Hz, but this this is probably due to very active trigger flooding DAQ - should collect enough data to construct PSDs and take a look at the pulses. |
