| 0030 | Fill N2 cold trap full. |
| 0130 | Start taking Ba-133, charge-only data, triggering on phonon channels (25 ADC bins), 0.4096 ms trace length, 100 μs trigger delay: 07120721_0128. First of half-hour series at varying bias voltages: -/+2.0 V; +/-2.0 V; -/+2.5 V; etc. |
| 0445 | DAQ crashed while taking -/+2.5 V data set. Reset connections with boards, zapped SQUIDs on both boards, flashed detector and tried again from -/+2.5 V: data series 07120721_0441. |
| 1526 | Filled LN2 cold trap. |
| | Fed Cricket (7 pellets). |
| 1632 | After zapping the SQUIDS the first time around, the tempearture didn't go below 63 mK. Fluctuated around higher end of 63 mK. |
| | rd 30 on DCRC 32 read 0A00. Unplugged DCRC 32, waited, plugged it back in. Powered up the board again. |
| 1646 | Temperature slightly dropping. Looks better. |
| 1649 | Zapped DCRC 32 SQUIDS again. Set up timing link. |
| 1654 | Flashed detector - 15 sec for Dib 2, 30 sec for Dib 1 |
| 1900 | Tried to take data again earlier, but DAQ crashed before taking a single pulse. Had to reset everything, zap SQUIDs, flash detector. Attempted to take data again, but found timing link was no longer present. Stopped run and set it right before trying again. This time, success! Data acquisition started from +/-5.0 V: data series: 07120721_1853. |
