| 0015 | Tighten screws around indium flanges. |
| 2150 | IVC pressure 7.4E-5 mbar. Isolate turbo pump and open line to leak checker. |
| 2155 | Background helium leak rate 1.2E-9 mbar l/s. Commence spray test on indium seals. |
| 2215 | Helium leak rate increased gradually to 2E-9 mbar l/s: no gross leak. Isolate leak checker and open line to turbo pump. |
| 2245 | Fill N2 cold trap full. Isolate nitrogen cold trap 2 from He-4 pump and place in nitrogen bath. |
| 2315 | Close gate valve and condenser line speedivalve to isolate fridge. Close all valves on IGH to stop pumping lines to atmosphere. Commence cryocleaning mixture through nitrogen cold trap 2. |
| 2345 | Dewar raised. Evacuate dewar. Isolate turbo pump and open line to leak checker. Background helium leak rate 2.3E-9 mbar l/s. Overpressurise dewar with He-4 gas. No change in leak rate, therefore no gross leak. |
| | Evacuate 1 K pot. |
| 2355 | Fill IVC with 4.6 mbar N2 gas. Commence nitrogen transfer. |
