| 955 | Cease turbopumping on fridge lines. Hook up scroll pump to He4 rotary pump manifold and pump out line leading to He cylinder. Add He gas to G1 lines through vent. |
| 1010 | G1: 935mbar, P1: 40ubar, G2: 0mbar. Mixing chamber temperature: 299K. |
| 1012 | With Gate and Condenser line speedivalves open, open V1. G1 drops to ~160mbar and settles. |
| 1015 | P1 finally begins rising. Currently at ~75ubar. |
| 1020 | G1: 150mbar, P1: 160ubar, G2 still at 0. |
| 1033 | G1: 133mbar, P1: 320ubar, G2: 0. Close V1. Add gas from line between V7 and V2 to G1. G1 rises to 205mbar, P1: 340ubar. Open V1. G1 drops to ~142mbar, P1 stays at 340ubar. |
| 1041 | G1: 135mbar, P1: 400ubar, G2: 0. Close vent valve. Open V5A, V2A, V7, V11A, V13A, and V6 to pump out He gas through fridge lines. |
| 1102 | G1: 114mbar, P1: 300ubar, G2: 0. Open V2 to pump from both sides of fridge. |
| 1115 | G1: ~2mbar, P1: 360ubar. Open V3 to aid in pumping out. P1 begins dropping more. |
| 1123 | Switch to turbopumping to pump out fridge lines. P1 at 220ubar. |
| 1129 | Switch to scroll pump and close V6 in preparation for second throughput test. |
| 1134 | Close all valves on IGH. G1: 2mbar, P1: 170ubar, G2: 0mbar. |
| 1145 | Open V2, V3, V11A, V13A in preparation for adding He gas. Open V7 and let G1 and G2 rise. Once G2 reaches 550mbar, close V7 to stop adding He gas. When G1 and G2 stabilize, close V2, V3, and open V1. Throughput test yielded flow of ~21mbar/min. Open V7 and V6 to pump out through fridge lines. G1 at ~ 218mbar. |
| 1155 | P1: 20.0mbar. Open V2 to pump from both sides of fridge. |
| 1205 | Open V3 to aid in pumping out. |
| 1225 | Close all valves on IGH. P1 at 360ubar. Add more He gas to lines. |
| 1230 | When G1 reaches 550mbar, close V7. G1 and G2 stabilize at 510mbar and 470mbar respectively. Close V2, V3, and open V1. Throughput rate of ~17mbar/min observed. |
| 1235 | Add more He gas to lines and repeat throughput test. G1 stabilized at 597mbar, and a throughput rate of ~17mbar/min observed. |
| 1345 | P1 at 85ubar. Close V6 and then all lines on IGH. Close condeser line speedivalve and Gate valve. |
| 1400 | Begin pumping out IVC with scroll/turbopump. |
| 1430 | Raise dewar. |
| 1635 | Add 4.6 mbar He exchange gas to IVC. Pump and flush the main bath, and commence LN2 transfer. |
| 1830 | Nitrogen transfer complete. Attach ping-pong ball. Mixing chamber temperature 122 K and falling. |
| 2300 | Mixing chamber temperature 77.7 K. Commence evacuation of exchange gas out of IVC. |
