| 0625 | Flash for one hour, followed by cool down for 2 hours. Then take 3 hour-long Ba-133 data series at -/+3 V bias, followed by three 60-minute Ba-133 data series at +/-3 V bias. Flash all LEDs for 6 seconds between data series with usual settings, and wait 20 minutes for cryostat to cool. Finish with a 20 minute flash and 2-hour cool down. |

| 1850 | DAQ crashed on first event from first -/+3 V data series 07121020_0929. It appears as though the connection to DCRC32 was lost. |
| 2020 | After a bit of digging around, found the problem. Port 5000 on DCRC32 had not been released after test run's flash and cool down. As a result, when DAQ tried to connect to DCRC32 at the start of the first -/+3 V data series, the port was blocked. Side 1 may have been under bias for a few hours, but a one hour flash should be enough to neutralise the crystal. |
| | Start data acquisition again. Flash for one hour, followed by cool down for 2 hours. Then take 3 hour-long Ba-133 data series at -/+3 V bias, followed by three 60-minute Ba-133 data series at +/-3 V bias. Flash all LEDs for 6 seconds between data series with usual settings, and wait 20 minutes for cryostat to cool. Finish with a 20 minute flash and 2-hour cool down. |
