Cryopumping of hydrogen and helium
Abstract
Results obtained in numerous tests on small and large cryopumps cooled to 4.2 K by LHe or between 10 to 20 K by closed-cycle helium refrigerator are summarized. Then, measurements of the compound cryopump, designed to work on Tokamaks to handle the exhaust gases from the Torus are presented.
