| 1040 | Pull out LN2 cold traps from bath. G2=661 mbar. |
| 1100 | G2=653 mbar. Close 11A. |
| 1120 | G2=655 mbar. Open 11A, close 11B. |
| 1140 | G2=657 mbar. Open 11B. |
| 1305 | Stop pumping on cold traps, and place them in the bath. Fill LN2 cold trap bath full. G2=659 mbar. |
| 1350 | Commence throughout test at 104 K through cold trap 1. Open dump, G2=663 mbar, P1=0.24 mbar, G1=1.5 mbar. Background leak rate at 6.5E-9 mbarL/s. During throughput test G1 rose to 550 mbar and dropped to 59 mbar once V1 was opened. It then rose with a flow rate of 22 mbar/min. Pump mixture back to dump. No change in leak rate. |
| 1405 | Repeat throughput test through cold trap 1 with background leak rate of 7.2E-9 mbarL/s, G1=0.6 mbar, P1=17 ubar, G2=663 mbar. During throughput test G1 rose to 567 and then dropped to 60 mbar when V1 was opened. As before, G1 began to rise with a flow rate of 22 mbar/min. No change in leak rate. Pump mixture back to dump. |
| 1450 | Prepare to cryopump mixture out of pump exhaust. G1=1.3 mbar, P1=17 ubar, G2=661 mbar. When G1=782 mbar, close V4 (isolate dump from cryopump), and insert cryopump back into LHe dewar. Finish cryopumping. |
| 1600 | Commence LHe transfer (0.0%). Add 5.4E-2 mbar He exchange gas. |
| 1757 | End LHe transfer (75.0%). Current mixing chamber temperature at 118 K. |
