| 1435 | Tower temperature reads “vmix ovl” |
| 1515 | Filled LN2 cold trap. |
| 1637 | 1K pot was running at 1.33K. Open the needle valve a little bit more to set temperature to ~1.5K. 1K pot temperature went to 1.66K suddenly and then slowly dropping. Tower Temperature 54.5mK. |
| 1648 | Power up DCRC boards, temperature went up from 53.1mK, then dropped. |
| 1800 | Start flashing detector. |
| 2000 | Stop flashing detector. |
| 2100 | Tower temperature still high at around 400 mK. Pressures in G1 & G2 around 60 mbar: it looks as though there is very little circulation. |
| | Resistance of temperature sensor in still is a little higher than it should be at over 5 kΩ. Perhaps it is time to turn on the still heater. |
| | Still heater turned on; power 1 mW. |
| 2130 | Tower temperature has fallen to 60 mK. Looks like still heater did the trick. |
| | Resistance of still thermometer is a little lower than usual at 4.4 kΩ (should be around 4.6 kΩ). This is probably alright. |
| | Pressures in G1 & G2 slightly higher at 70-80 mbar, but still a little low. As long as the base temperature hovers around this level, it might be better not to fix what isn't broken. |
| 2230 | Tower temperature has stabilised at 54 mK. |
| 2240 | Start data series: 07110508_2236; +3 V bias DIB1; -3 V bias DIB2; Ba-133 source 13” below top of mu-metal shield; 40 ADC bins trigger threshold on all charge channels; charge-only. |
