摘要：

A prototype cryomodule to test the performance of the crab cavities for the HiLumi LHC is currently being designed and scheduled to be installed on SPS at CERN prior to LS2 (long shut down). The cryomodule design consists of a unique open access structure, facilitating loading of the cavity string from the sides. It also provides access to internal components quickly and easily, even after installation. Design of the radiation shield and the cooling scheme for introducing thermal intercepts at intermediate temperatures, particularly for the high power RF couplers, is critical to achieving a desired stability at the cavity operating temperature of 2 K, as well as keeping the cooling power within the limits of the cryoplant available in the SPS test area at CERN. This paper describes the results of the thermal and mechanical analysis of the design for the radiation shield and thermal intercepts developed in the process. (C) 2015 The Authors.
