| 0910 | Overnight external pressure sensor reached down to 5.4E-3 mbar (this might be lower, since this gauge tends to get stuck). Isolate turbopump, and see no immediate change in external pressure sensors. |
| 0922 | Still no change in external pressure. Turn on leak checker. |
| 1005 | Leak check pump room manifolds. Background leak rate of 8.8E-8 mbarL/s. Occasional spikes to 9.3 mbarL/s, but spikes were non-repeatable. No indication of leak on pumping manifolds. |
| 1110 | Raise dewar, pump out with scroll pump. |
| 1200 | Perform leak test on fridge lines by purging dewar with He gas. Initial leak rate on fridge lines was measured at 1.8E-7 mbarL/s. Adding He gas to the bath resulted in no obvious rise in leak rate; no leak detected. |
| 1140 | Start turbo pumping on condenser line and still line. |
| 1245 | Add He gas to still line to check throughout to condenser side. As soon as gas was added to still line, a change in pressure was registered on condenser line side, indicating a good (though not accurately measurable) throughput. Commence pumping on both sides of the fridge with the scroll pump and switch to turbo pump once the pressure is sufficiently low. |
| 1510 | Reconnect system to standard positioning. Pump system out with scroll pump. Switch to turbo pump. |
| 1630 | Perform throughput test with standard setup. Add He gas until G1 reads 570 mbar. Conduct throughput test by opening V1 (do not pump out G1 before hand; G1 drops to 46 mbar and then begins to rise. Throughput test gives a rate of 7 mbar/min. |
| 1640 | Commence pumping out of fridge lines with scroll pump. Once low enough, switch to turbo pump and leave overnight. |
