| Status | Run 74 in progress. Warming up after second occurrence of IVC leak during initial LHe transfer. Helium in Cryostat Vacuum Jacket. N2 in IVC. Mixture in dump. |
| 1545 | Matt enters lab |
| 1545 | MC(Cernox) = 276 K. |
| 1545 | IVC = 0.75 bar on mechanical gauge. Let's put more N2 into it. |
| 1550 | Slowly fill IVC with N2 → 0.93 bar on mechanical gauge |
| 1555 | Close off IVC then switch pumping line over to CVJ and pump out line |
| 1555 | Check pressure in CVJ: 0.19 mbar |
| 1555 | Begin pumping out CVJ, with Scroll for a minute than @ <0.1 mbar switch to Turbo |
| 1600 | Turbo on CVJ = 1.2 μbar. |
