| 0005 | Finished third clean-out. No improvement over last one: pressure in P2 6.5 mbar. |
| 0030 | Finished fourth clean-out. Pressure in P2 4.5 mbar. |
| | Valve 12A leaks, so open valve 2 on IGH. Leave traps to pump out overnight. |
| 1225 | Mixing chamber temperature 78 K. Start pumping exchange gas out of IVC. |
| | Fill N2 cold trap full. |
| | Stop pumping on nitrogen cold traps. Start cryocleaning mixture through nitrogen cold trap 2. |
| 1445 | Electrical check at 77 K: no problems. |
| 1500 | 77 K resistance check of thermometers: MC: 2255 Ω, Cold Plate: 2315 Ω, Still: 2292 Ω |
| | Pressure in IVC: 1.9E-6 mbar |
| 1530 | Begin blow-out of LN2; Background leak rate for IVC: 5.4E-9 mbar l/s |
| 1645 | End blow-out of LN2; Note leak rate: 1.1E-8 mbar l/s |
| 1740 | Pressure in main bath after evacuation is 0.026 mbar: no residual liquid nitrogen in main bath. |
| | Pump mixture into dump in preparation for throughput test. |
| 1840 | First throughput test yields 30 mbar/min. Second throughput test yields 49 mbar/min. Pump mixture into dump. |
| | Background helium leak rate 1.0E-8 mbar l/s. No change during throughput test. |
| 2120 | Fill IVC with 0.01 mbar He-4 exchange gas. |
| | Start first liquid helium transfer. |
| 2335 | Stop first liquid helium transfer. Liquid helium level 70.7%. |
| 2345 | Fill N2 cold trap full. |
| | Start cryocleaning mixture through nitrogen cold trap 2. |
