| 1915 | Start flashing detector for 8 hours followed by 2 hour cooldown and data acquisition. Each bias set will consist of three 30-minute data series, interspersed by 30 seconds of flashing and 20 minutes of cooldown. Qi = Qo for each data series. Data acquired for following biases in order: +4 V DCRC31, -4 V DCRC33; -4 V DCRC31, +4 V DCRC33. Trigger thresholds set at DCRC31: 40 Qi, 20 Qo, DCRC33: 35 Qi, 20 Qo. |
| 2100 | DAQDAQ2 has encountered a flashing issue in which the mixing chamber temperature does not increase above 82mK during automated flashing. DAQDAQ2 has been stopped, and manual flashing commenced. |
