| | Begin another warm up and pump out |
| 1454 | Tower(RoX)/Tower(U28)/MC(H35)/Coldplate = -/-/32.8/152 mK, Still(P1) = 1.14 K / 0.12 mbar / 0 mW, G1/G2 = 169/143 mbar, 1K Pot(P2) = 45° / 1.65 K / 28 mbar, MB = 63.4% |
| 1454 | Close V6 to stop circulation (Put 0% in the V6 tab in the IGHFrontPanel Vi and wait). |
| 1500 | V6 is now fully closed (light is off on IGH, Still pressure (P1) is rising (currently 3 mbar), Condenser pressure (G1) falling). Turn off 3He pump (Click Settings in the IGHFrontPanel.Vi and uncheck 3He Pump tab and press Ok) |
| 1513 | Close 1K Pot needle valve |
| 1516 | Open V3 to let mixture from Condenser side into Still side. |
| 1516 | MC(H35) = 0.48 K |
| 1517 | Turn off DAQ programs and unplug DCRCs 1,2 & 3 |
| 1519 | Turn on Still and MC heaters to 20 mW each (Goto Settings in IGHFrontPanel.Vi, Select On in P(Still) and type 20 for Still and 20000 for M/C, Click Ok) |
| 1529 | Close 1K Pot speedivalve, V4a, 4He pump inlet valve. Turn off 4He pump. Close recovery valve to 4He pump outlet. NOTE: remember to open recovery valve when the pump is turned back on. |
| 1546 | Started filling LN2 cold trap bath |
| 1554 | Stopped filling LN2 cold trap bath |
| 1550 | MC(H35)/1KPot = 3.85/3.82 K |
| 1550 | G1(fridge) = 764 mbar. Open V9 to release mixture into dump to keep it from going over 1000 mbar |
| 1639 | MC temp starts to rise more quickly |
| 1643 | MC(H35)/1KPot = 5.18/4.36 K. Temperatures are about to be relatively flat. |
