| 1050 | Commence leak checking IVC in preparation for LN2 blowout. Current background leak rate at 3.4E-9 mbarL/s. Commence blowout. |
| 1100 | Leak rate spikes to 4.0E-9 mbarL/s, but settles back to 3.4E-9 mbarL/s. |
| 1200 | Finish LN2 blowout. Leak rate gradually rose to 4.2E-9 mbarL/s. |
| 1250 | Isolate scroll pump from P2. Open Cold Trap 2 to P2. 190mbar accumulated in P2. Cold Trap 1 did not cause a rise in P2. Open pump and commence pumping on cold traps as they warm. |
| 1300 | Commence cleaning both LN2 cold traps. |
| 1330 | Finish round of cold trap cleaning. |
| 1400 | Flush main bath with He gas. |
| 1430 | G2 at 1.5mbar. Attempt to pump out before attaching cryopump. Cannot pump out G2. Indicates issue with pressure sensor instead of actual pressure. |
| 1455 | P1=0.32 mbar, G1=0.5 mbar, G2=6.8 mbar. Insert cryopump into LHe. Open dump valve and G2 rises to 596 mbar and stabilizes, slowly dropping to 591 mbar. Pull cryopump out of dewar (to neck), and slowly open cryopump valve. G2 initially drops to 579 but then rises and stabilizes to 586 mbar. |
| 1515 | Close 13A and open 12A and 5 (commence pumping on cryopump); G2 rises to 646 quickly then continues increasing at a slower rate. Remove cryopump from dewar with G2=666 mbar and G1=12 mbar. Allow cryopump to warm to room temperature. |
| 1610 | G1=0.8, P1=0.34 mbar, G2=666 mbar. Start cryocleaning. |
| 1640 | Stop cryocleaning and pump to dump. |
| 1645 | G1=22.4 mbar, G2=671 mbar, P1=20 ubar. |
| 1655 | Start cryocleaning. |
| 1730 | Stop cryocleaning. Pump to dump. |
| 1800 | P1=16 ubar, G1=0.4 mbar, G2=671 mbar. |
| 1837 | Close manual valves on dump. Close all valves. |
