| 1630 | MC(Cernox)=10.04K. Mixture in dump. |
|---|---|
| 1647 | Close IVC valve at the top of the fridge. Valved out turbo pump. Let 4.6 mbar He gas into vacuum manifold. Then open cryostat vacuum jacket valve to let this into the vacuum jacket. Vacuum Jacket → 0.12 mbar. Close CVJ valve. |
| 1650 | Let He gas into IVC. First pumpout the line with Turbo(since we are still below 1e-1 mbar). Two tube-lengths of He gas (tube from wall to pump manifold). IVC → 0.34 mbar. |
| 1700 | MC temperature dips and then rises quickly, 10→12 K in 12 minutes. |
