| 1600 | Talked to Matt about the possible reasons to see high G1 and we think that there was some mixture left in the cold trap during last cryoclean. So, we will pump the mixture to the dump. G2 at 694 mbar(with V9+3He pump ON). Expecting it to be above 700 mbar |
| 1638 | Check G1 after opening V12A+speedivalve. G1= 641 mbar. Place the LN2 cold trap 1 in LN2 and wait for a few minute to let it cooldown completely. |
| 1713 | P1 = 0.012 mbar, G1 = 1.2 mbar and stable. Close all valves and turn off 3He pump, leaving 716.8 mbar in dump |
| 1730 | Check contents of warm LN2 Trap 2: 5.9 mbar (7.2 on G1). Pump it out with the scroll pump. |
| 1716 | G1 = 2.6 mbar and stable, stop pumping on Trap 2 |
| 1737 | Insert LN2 cold trap 2 and begin filling cold trap dewar with LN2 |
| 1739 | Begin cryocleaning mixture through cold trap 2 following the procedure in procedure:cryoclean_mixture |
| 1744 | Open V6 to 12.2% to restart flow |
| 1759 | Open V6 to 12.4% to restart flow |
| 1841 | End cryocleaning mixture through trap 1. Pump mixture to dump |
| 1858 | P1 = 0.007 mbar, G1 = 2.1 mbar and stable. Close all valves and turn off 3He pump, leaving 719.4 mbar in dump |
| 1901 | Remove cold trap 2 from the LN2 bath to warm up overnight |
