| At line 14 added 4 lines. |
| + * take the special assembly to connect the pumping |
| + line and the condenser line with the stick |
| + * pump out the adapter piece |
| + * connect a turbo pump to the IVC, start te pump, but do not yet open the IVC valve. |
| Lines 16-18 were replaced by line 20 |
| - * cool down the heat exchanger of the variox or magnet |
| - * pump the IVC (5 min. with sorb temperature set to 40 K, |
| - then 1 h without sorb heater) |
| + The following steps can be done automatically in SEA, under "main diltuion control" |
| Lines 20-22 were replaced by lines 22-27 |
| - * if not yet done, take the special assembly to connect the pumping |
| - line and the condenser line with the stick |
| - * pump out the adapter piece for 15 min |
| + * ("cool") cool down the heat exchanger of the variox or magnet |
| + * When the stick is cold (< 4K, ins SEA "readyforpump") pump the IVC by clicking on "sorbpump" and opening |
| + the IVC valve, which is already connected to a running turbo pump. |
| + This heats up the VTI to 5 K, which might take a while. After 20 min. with sorb temperature set to 40 K, |
| + then 15 min without sorb heater, the "condense" step starts automatically. |
