| 1230 | Filled LN2 cold traps. |
| 1300 | Conducted electrical check at 77.7K. Everything seems fine, but DIB 1 had found FET Tsense+/FET Heater- open at room temperature, but it has a potential of 1.08V now. This was not seen on any of the other DIBs. |
| 1725 | IVC pressure 8.6E-6 mbar. Open line to leak checker and isolate turbo pump. Background helium leak rate 3.2E-9 mbar l/s. Commence blow out of nitrogen. |
| 1830 | Nitrogen blow out complete. Helium leak rate 4.4E-9 mbar l/s: no gross leak. |
| 1850 | Evacuate main bath & 1 K pot, and overpressurise with He-4 gas. Background helium leak rate 7E-9 mbar l/s; no change witnessed after main bath was overpressurised, therefore no gross leak. |
| 1855 | Open line to turbo pump and isolate leak checker. |
| 2005 | Fill IVC with 0.063 mbar He-4 exchange gas. Commence first helium transfer. |
| 2350 | Mixing chamber temperature drops below 10 K. Start pumping He-4 exchange gas out of IVC. |
