| 0335 | Start data acquistion, triggering on charge channels with 0.1 ms trigger delay and 0.4096 ms trace length. OR charge trigger threshold 40 ADC bins for all charge channels, and coincidence time set to 10 μs. Flash for one hour, followed by cool down for 2 hours. Then take four 30-minute data series each at -/+3 V, +/-5 V & -/+5 V biases. 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. |
| | Phonon pulses look reasonable; whatever was aflicting them yeseterday seems to have cleared up. Trigger rate is a little above 3 Hz. |
| | Pressures in G1 & G2 are 78 mbar & 81 mbar respectively: a little higher than expected. We saw a similar rise during Run 31, and whether this is related to the loss in base temperature is unknown. Our base temperature is stable at 59.6 mK. |
| 0345 | Take advantage of detector flash to fill N2 cold trap partially full: perhaps a litre shy. Shall top it up before leaving. |
| 0510 | Cryostat cooling from flash. Fill N2 cold trap full. |
| 1015 | Fed Cricket 3 pellets. |
| 1800 | Fed Cricket 4 pellets. |
| 1805 | Commence helium transfer. Helium liquid level 20.3%. |
| 1850 | Cease helium transfer. Helium liquid level 92.2%. |
| 1900 | Fill N2 cold trap full. |
