| 0910 | Fridge has warmed to 297 K. With P1 previously at 0.4 mbar, open gate valve to allow gas from fridge line to P1. P1 rose to 1.1 mbar. Commence pumping on fridge lines with turbo pump. External pressure sensor reads 5.4 mbar. |
| 1200 | Filled LN2 cold trap full. |
| 1345 | Currently G1=1 mbar, P1=28 ubar, and G2=0 mbar. Fridge temperature at 298 K. Lower dewar fully. |
| 1353 | Open vent valve, V7, V11a (and speedivalve), and V12a to let in 837mbar of He gas into G1. P1: 30ubar. Open V1. |
| | G1 drops to ~756. P1 already rising. Currently at ~200ubar. |
| 1415 | G1=728 mbar, P1=26 mbar, and G2=0 mbar. Close V12A and cold trap 1 speedivalve to isolate cold trap. Open V5A, V2A, V7, 13A and V6 to commence pumping out. |
| 1435 | G1= 530 mbar, P1=3 mbar, and G2=0 mbar. Open V2. |
| 1535 | Finish pumping out. Add 666mbar of He gas to G1 and isolate from LN2 cold trap 1. P1: 80ubar. Open V1. |
| 1600 | G1: 51mbar, P1: 130ubar, G2: 0mbar. |
| 1610 | G1: 49mbar, P1: 170ubar. Pump out through V6. |
| 1700 | G1: 44mbar, P1: 0.2mbar. Close V13a and V11a and open V2 to aid in pumping out. |
| 1715 | Close gate and condenser line speedivalve and close all IGH valves. |
| 1800 | Remove He cold trap from condenser line ports on IGH and fridge; put condenser line back in proper place. Attach He cold trap to gate valve using a series of adapters, and to speedivalve on He-3 pump intake lines directly before V6. Blank off still line leading to V6 (directly before this speedivalve). Still line is successfully cut out of circulation, with lines going from gate valve, to He cold trap, to V6 and intake lines. Commence pumping on these lines and condenser line with scroll pump. |
| 1805 | Switch from scroll pump to turbo pump. |
| 1815 | Open gate and condenser line speedivalve to commence pumping on fridge lines with turbo pump. External pressure sensor reads 6.3 mbar. |
