| 0115 | Nitrogen level meter resistance 1.34 kΩ. Nitrogen transfer complete. Attach ping-pong ball. |
| 1115 | Started pumping out exchange gas from IVC. Current temp is 91 K. |
| 1305 | Fill N2 cold trap full. |
| | Stop pumping on mixing chamber lines and start cryocleaning mixture through nitrogen cold trap 2. |
| 1540 | Background helium leak rate 3.7E-9 mbar l/s. Start blowing liquid nitrogen out of main bath. |
| 1635 | Fill N2 cold trap full. |
| 1700 | Nitrogen has been blown out. Helium leak rate 4.2E-9 mbar l/s: no gross leak. |
| | Interrupt cryocleaning and pump mixture into dump in preparation for throughput test. |
| 1735 | Perform electrical check at 86 K. No new problems witnessed. |
| | Main bath evacuated. No nitrogen remains. |
| 1805 | Conduct throughput test: 23 mbar/min; 28 mbar/min. A little low, but confident that mixture is clean due to large number of cryocleaning cycles this run. Background helium leak rate 7.3E-9 mbar l/s. Leak rate increased to 7.4E-9 mbar l/s during throughput test. Increase just looks like background. Safe to conclude there is no leak between mixing chamber lines and IVC. Pump mixture into dump in preparation for cryocleaning. |
| 1810 | Overpressurise main bath with helium gas. Helium leak rate 7.4E-9 mbar l/s: no change from background. |
| | Evacuate 1 K pot. |
| 1825 | Fill IVC with 0.25 mbar He-4 exchange gas. |
| 1900 | Commence first helium transfer. |
| 2035 | Pump out exchange gas at 12 K. |
| | Conclude helium transfer. Helium liquid level 88.6%. |
| 2315 | Close gate valve and condenser line speedivalve. Restart cryocleaning mixture through nitrogen cold trap 2. |
