Design of a two-stage cryopump with hydrogen-helium separation capability for fusion reactor application

During the regeneration process of the torus cryopumps in CFETR, separating the majority of unburned fuel from desorbed gas mixture can increase fuel recycling efficiency. Given this situation, this paper proposes a two-stage cryopump concept with hydrogen–helium separation capability, based on the...
