| Status | Warming after finding a blockage. LN was blown out so MB full of He gas, IVC has He transfer gas |
| 1610 | Fill LN2 cold trap bath. Mixture has been sitting overnight exposed to both traps. |
| 1615 | MC(Cernox) = 131.4 K, Sorb = 225 K, IVC = 1.9 mbar |
| 1625 | Pump mixture from traps to dump. Dump (G2) = 789.0 mbar |
| 1635 | Remove LN2 traps from bath to let warm up |
| 1645 | Open V1 and V3, which opens the LHe cold trap to P1. P1 goes up from 0.016 to 0.026 mbar. |
| 1646 | Open condenser valve, which opens condenser to P1. P1 does not increase, goes down a bit, to 0.020 mbar. |
| 1647 | Open still gate valve, which opens still to P1. P1 increases slightly, to 0.022 mbar. |
| 1648 | Open V6 (3He pump is on, V9 is open) to pump fridge contents to dump. Pump down to 0.017 mbar on P1. |
| 1655 | Close V6 and remove LHe cold trap from bath to let warm up. V1 and V3 are open, watching cold trap pressure on P1. |
| 1705 | P1 spikes to 0.280 mbar, then falls to 0.040 mbar. I guess something boiled out of the LHe trap, then maybe started to condense into fridge lines. Quickly close gate valve and condenser valve. |
| 1710 | Pump LHe trap to dump. Then put LHe trap back into main bath (not sure it went down all the way though). |
| 1730 | LN2 cold traps are near room temperature, check the pressures: Trap 1 = 5.8 mbar. Trap 2 = 6.8 mbar; pump them out with scroll pump. |
| 1745 | Return LN2 cold traps to bath, fill bath. Prepare forward throughput test. Open still gate valve to watch pressure on P1. Open V13B to let mixture into Trap 2. Let mixture settle. |
| 1750 | Open V12B and V1 to let mixture into LHe trap |
| 1755 | Open condenser valve. P1 does not fucking budge. |
| 1800 | Pump mixture to dump. Dump (G2) = 790.3 mbar |
| 1810 | MC(Cernox) = 134.1 K, Sorb = 230 K, IVC = 1.9 mbar |
