| 1135 | Perform leak check on IVC, with sorb temperature at 19.4 K and mixing chamber temperature at 18.4 K. Background leak rate of 3.3E-9 mbarL/s. Opening the leakchecker to the IVC resulted in an immediate rise followed by a flatline at 1.4E-7 mbarL/s. There is a leak. |
| 1200 | Commence LHe transfer (2.9%). |
| 1238 | End LHe transfer (59.5%). |
| 1254 | Commence turbo pumping on IVC. |
| 1718 | With Sorb temperature at 17.8 K, prepare leak checker. |
| 1726 | Commence leak check on IVC with mixing chamber temperature at 18.2 K, the sorb temperature at 17.8 K and background leak rate of 1.4E-9 mbarL/s. |
| 1734 | Spraying wizard staff yielded a rise in leak rate to 1.9E-9 mbarL/s. Stop spraying to monitor change in leak rate when no gas is added. |
| 1744 | After 10 minutes, leak rate has decreased to 1.71E-9 mbarL/s. |
| 1810 | Leak check of all flanges leading to IVC resulted in a leak rate of 9E-9 mbarL/s, a slight increase on the background rate, but not significant. |
| 1829 | Commence pumping on IVC with turbo pump. Mixing chamber at 18.2 K and sorb at 17.8 K. |
