This paper presents the results of the design investigations and the manufacturing of cryosorption pumps for the Neutral Beam Test Facility 'MANITU' at Max Planck Institute for Plasma Physics (IPP) and the cryopump design analyses performed for the development of a test facility for the first ITER Neutral Beam Injector. The two identical cryopumps for IPP are foreseen to pump a hydrogen-throughput of 3 Pa m3/s (H2) with a pumping speed of 350 m3/s per pump. The pressure conditions must be maintained over 4 h pumping without regeneration of the cryopanels. For the ITER Neutral Beam Test Facility, design calculations to assess heat loads and pumping parameters of the cryopumps will be briefly described. © 2005 Elsevier B.V. All rights reserved.
