| 1320 | Mixing chamber temperature 77.2 K. Begin extracting N2 exchange gas from IVC. |
| 1330 | Fill N2 cold trap full. |
| 1840 | Isolate turbo pump. Start blowing out nitrogen. Background helium leak rate 1.5E-9 mbar l/s. |
| 1955 | Interrupt cryocleaning mixture. Pump mixture into dump in preparation for throughput test. |
| 2050 | Blow out of LN2 done! No gross leak! Leak rate: 1E-8 mbar l/s. |
| 2134 | 1st throughput test: 25 mbar/ min. 50 mbar/ min. We're not doing anymore tests. The mix has been cleaning for days! Why bother doing this test…? |
| | Leak rate 1.8E-8 mbar l/s. No leak between mixing chamber lines and IVC. |
| 2200 | Fill IVC with 0.1 mbar He-4 exchange gas. Start first helium transfer. |
| 2310 | Mixing chamber temperature 8 K. Pump out He-4 exchange gas. |
| 2330 | First helium transfer complete. Helium liquid level 92.2%. |
| 2355 | Fill N2 cold trap full. Close gate valve and condenser line speedivalve to isolate fridge. Restart cryocleaning mixture. |
