| 1945 | Miscalculated liquid helium evaporation rate last night. Came in and 1 K pot was at 5 K, main bath was empty, mixing chamber temperature climbing, pressures in P1 & P2 at around 900 mbar. Temperature profile shows this occurred at around 19:00. |
| | Interrupt circulation by closing valve V6 on IGH and commence helium transfer. Should be alright once 1 K pot gets going again. |
| | Fill N2 cold trap full. |
| 1955 | Helium liquid level 7% and 1 K pot pump has recovered; temperature 1.64 K. Commence manual circulation procedure. |
| 2300 | Fridge appears to have recovered. Manual condensation procedure completed (valve V6 on IGH fully open); mixing chamber temperature 155 mK and falling. Leave overnight. Still heater is off at the moment. |
