Thermostructural Analysis of Large Cryopumping Test Facility

To create high and ultra-high vacuum environments in large-size chambers for applications in space research, nuclear fusion, accelerators, etc., vacuum pumps with fast pumping speeds are essentially required. To cater to this need, one promising solution is the cryopump, which offers efficiency, a low cost, and applicability. The Institute for Plasma Research is working to develop large-size cryopumps and to develop performance testing and design validation for such cryopumps.
