Abstract

The accelerator driven sub-critical system ( ADS) in China is a kind of transmutation machine to minimize nuclear waste. As one of the important parts in ADS, injector I will be built at IHEP, CAS. Injector I needs two cryomodules operating at 2 K cryogenic environment to realize a 10 MeV proton beam energy. Each cryomodule includes seven spoke cavities and seven superconducting magnets. This paper describes the overall design of the cryogenic system, including the cooling flow chart, heat loads estimation, the structure of the operation cryomodule and some of the key components.
