Conclusions
The regeneration method here proposed is characterized by adequate energy efficiency and permits rapid regeneration of cryopumps of both sorptional and condensational type. Note that the method is compatible with complete automation.
Although the method has been demonstrated at 80 K in nitrogen and carbon dioxide, calculations show that it should also be effective at 20 K and 4.2 K.
