| 0155 | Stop data acquisition. Switch off external power supply and allow time to settle. Start flashing detector. |
| 0205 | Stop flashing detector. |
| 0230 | Started data acquisition, but triggering on noise. Copper shield did fall from DCRC board about an hour into the last run. It was replaced, and the pulses were checked, but it is possible that the noise increased over time. Will retake data series as events towards the end may be poor quality. This will be the last data set for this run. Flash detector for a few seconds. Wait for cool down. |
| 0245 | Start data series: 07120529_0242: -/+4 V, +/-1 V on QET D with external power supply. Test trace from external trace looks like sine wave. Not sure why, but have seen this before. Not sure of how to get rid of it, but it is likely to clear up as the run proceeds. Should be noted when analysing this data series. |
| 0445 | Finished taking data, but external power supply was off… I'm beginning to make mistakes, and there isn't enough helium left for another attempt. Time to give up and hope previous data set is good enough. |
| | Start warm up procedure. |
| 1149 | Filled LN2 cold trap. |
