Results obtained in numerous tests on small (approx. 1000 l/S) and large (approx. 10/sup 5/ l/S) cryopumps cooled to 4.2/sup 0/K by LHe or between 10 to 20/sup 0/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.
