| 0000 | Mixing chamber is very high at 798 mK and cooling is excruciatingly slow. I suspect that most of the He-3 content was extracted from the mixture. No point carrying on. Pump mixture out of dump and start warming up to 4.2 K. |
| 0010 | Fill N2 cold trap full. |
| | Stop 1 K pot. |
| 0020 | While I'm here, waiting for my bus, I might as well turn on the mixing chamber heater. Power supplied 10.0 mW. |
| 0035 | Turn off mixing chamber heater. |
| 0955 | Fed Cricket 3 pellets. |
| 1012 | Filled LN2 cold trap. |
| 1212 | Turned on Mixing Chamber Heater (10mW) |
| 1400 | Turn off mixing chamber heater. We have recovered 687 mbar of mixture. The difference can probably (hopefully) be explained by difference in dump temperature. |
| | Start evacuating IVC in preparation for leak check. |
| 1650 | Isolate turbo pump and conduct leak check. Helium leak rate is 2.0E-6 mbar l/s. Isolate IVC and pump out lines to leak checker. Leave for a few hours to check for leaks from main bath to IVC. |
| 2325 | Fill N2 cold trap full. |
| 2335 | Helium background leak level in pipes leading to IVC 8.4E-10 mbar l/s. Open up IVC, and helium leak rate is 2.7E-6 mbar l/s. |
| 2340 | Close off IVC, pump out lines to leak checker and leave overnight. Mixing chamber temperature 7.12 K. |
