| 1540 | Fill LN2 coldtrap tiny bit full. |
| 1650 | With full LN2 dewar, fill LN2 coldtrap full. |
| 1700 | Commence cryocleaning through coldtrap 2 with initial G2 at 694.6 mbar. V6 opened to 12.6%. |
| 1730 | Flow restarted by increasing V6 to 13.0% |
| 1915 | Cease cryocleaning and pump mixture to the dump. Feed Wicket Alexander. |
| 1930 | With G2=627.6 mbar, G1=0.2 mbar and P1=6 ubar, opening gate valve to pump on mixing chamber lines (V6, V5, V12, and V9 left open to continue pumping mixture to dump). No change in G2, suggesting that the mixing chamber lines were indeed empty (WHEW!). Continue pumping on cold trap 2 and mixing chamber lines overnight. Pray to the old gods and the new that no pressure change occurs overnight. |
