| 1120 | Adding rest of the mixture and record Baratron zero point. |
|---|---|
| Baratron: 0.065 VDC==8.55 mbar | |
| Added all mixture to circulation. Wait enough time to get to steady state. | |
| 1440 | Reached steady state. MC(H35) = 57.4 mK, Coldplate= 72.7 mK, Still= 1.05 K, Still Pressure= 206 mTorr(P1=350 mTorr), Return Pressure= 420 mbar, Dump level= 0.06 VDC |
| 1450 | Doing one-shot to see the effect on MC till Still dries. Open V9, Close V8. |
| 1500 | MC temp dropping, Baratron increasing, Still Pressure stable at 175 mTorr (P1=300 mTorr), Return pressure lowering , currently at 200 mbar |
| 1510 | MC(H35) = 53.1 mK, Coldplate= 72.7 mK, Still= 1.05 K, Still Pressure= 162 mTorr(P1=300 mTorr), Return Pressure= 180 mbar, Dump level= 0.759 VDC |
| 1520 | MC(H35) = 52.2 mK, Coldplate= 72.7 mK, Still= 1.05 K, Still Pressure= 155 mTorr(P1=290 mTorr), Return Pressure= 140 mbar, Dump level= 0.920 VDC |
| 1530 | MC(H35) = 52.2 mK, Coldplate= 72.7 mK, Still= 1.05 K, Still Pressure= 154 mTorr(P1=290 mTorr), Return Pressure= 130 mbar, Dump level= 1.002 VDC. MC flattened. |
| Close V9 and open V8 to restart circulation. |
