| 0955 | Fed Cricket 3 pellets. |
| 1010 | Filled LN2 cold trap. |
| 1340 | Mixing chamber temperature 7.05 mK and appears to be holding steady. Close all valves to mixing chamber lines in fridge. Helium leak rate in pipes leading to IVC 1.4E-9 mbar l/s. Open up IVC and helium leak rate rises to 2.2E-6 mbar l/s. It is doubtful there is a superfluid leak. |
| | Isolate IVC and leak checker. Use turbo pump to evacuate pipes to IVC. |
| 1400 | Start helium transfer. Helium liquid level -0.1%. |
| 1445 | End LHe transfer (88.4%). |
| 1630 | Fed Cricket 4 pellets. |
| 2340 | Fill N2 cold trap full. |
| | Uncalibrated He-3 leak rate in pipes leading to IVC 1.8E-10 mbar l/s. Open up IVC and uncalibrated He-3 leak rate falls to 1.7E-10 mbar l/s. Let's see what things look like in the morning, but it appears that there isn't any trace of He-3 which would rule out a leak from the dilution unit. |
| 2355 | Start cryocleaning mixture through nitrogen cold trap 2. |
