| 1110 | Filled LN2 cold trap. |
|---|---|
| 1140 | Begin LHe transfer (6%). |
| Fed Cricket 4 pellets. | |
| 1226 | End LHe transfer (89%). |
| 1330 | Plugged in DCRC31 and zapped all SQUIDs. Timing link has been set up. |
| 1918 | Temperature of mixing chamber keeps rising. Increased from 50.5 mK gradually to 53.2 mK (currently). Not sure why. |
| 2014 | Temperature is now at 51.0 mK. Not sure why there was a rise in temperature. I hope this doesn't happen during data taking. |
