| 0030 | Raise dewar. Evacuate main bath and overpressurise with helium gas. Background helium leak rate 2.5E-9 mbar l/s. Helium leak rate rises to 2.7E-9 mbar l/s - rate of rise that expected from background: no gross leak. |
| | Evacuate 1 K pot. |
| | Fill N2 cold trap full. Cease pumping contents of mixing chamber to dump, close gate valve & condenser line speedivalve. Start cryocleaning mixture through nitrogen cold trap 2. |
| 0110 | Fill IVC with 5.4 mbar nitrogen exchange gas. Start nitrogen transfer. |
| 0250 | Performed quick electrical check. LED 2 on DIB 3 still closed in reverse direction. However, LED 1 on DIB 3 yields conductivity <1 nS in reverse direction and whatever problem was aflicting Qo bias to QET return on DIB 2 has disappeared. Mixing chamber temperature 247 K and falling. |
| 0330 | Nitrogen level meter resistance 1.33 kΩ. Nitrogen transfer complete. Attach ping-pong ball. |
| 0510 | Fill N2 cold trap full. |
| 1000 | Fed Cricket 4 pellets. |
| 1015 | Filled N2 cold trap full. |
| 1728 | Fed Cricket 4 pellets. |
| 2015 | Mixing chamber temperature 79.8 K. Start pumping nitrogen exchange gas out of IVC. |
