Previous Day

  • Lab in-personnel: Zach, Ping, Himangshu
Status Run 78 Preparation. Tower Installation in progress. IVC open. Turbo valved out
1355 Check contents of warm LN2 Trap 1: 13.3 on G1. Pump it out with the scroll pump.
1359 G1 = 2.3 mbar and stable, stop pumping on Trap 1
1403 Check contents of warm LN2 Trap 2: 5.7 on G1. Pump it out with the scroll pump.
1405 G1 = 1.5 mbar and stable, stop pumping on Trap 2
1410 Insert cold trap 1 into and begin filling the LN2 cold trap dewar with LN2
1415 Begin cryocleaning mixture through cold trap 1 following the procedure in procedure:cryoclean_mixture
1422 Open V6 to 11.9% to restart flow
1435 Open V6 to 12.2% to restart flow, then reduce to 12.0%
1500 Open V6 to 12.3% to restart flow, then reduce to 12.1%
1605 End cryocleaning mixture through trap 1. Pump mixture to dump
1610 Bottom IVC cap installed and tightened, begin pumping out IVC with scroll pump
1625 P1 = 0.095 mbar, G1 = 1.9 mbar and stable. Close all valves and turn off 3He pump, leaving 707.1 mbar in dump
1625 Remove cold trap 1 from the LN2 bath to warm up overnight
1636 Scroll on IVC = 0.14 mbar, not wanting to go below 0.1 mbar, switch to turbo anyways
