| 1447 | Fridge was found to be warm (9 K), with He bath empty. |
| 1515 | Commence LHe transfer (-1.0%). |
| 1520 | Fill LN2 cold trap full. |
| 1625 | End LHe transfer (92.3%). Mixing chamber has dropped back down to 1.00 K. |
| 1705 | Due to temperature (and thus pressure) increase, some mixture was pumped into dump. Periodically open V14 to allowing mixture from dump into lines. Although P1 does not drop from 1000 mbar with V14 left open, it seems as though most mixture has been released from the dump, since G2 has begun dropping from around 800 mbar. That said, there is likely more mixture left in the dump that could be added to the system later when we have more time to monitor. Close V14, and G1, G2, mixing chamber temperature and 1K Pot temperature drop. |
| 1710 | Leave lab with G1= 635 mbar, G2= 610 mbar, P1= 0.65 bar (all dropping), Mixing chamber temperature at 123 mK and rapidly dropping, and 1K Pot at 1.76 K. System will hopefully be ok overnight. |
