摘要
为了优化CM4低温恒温器的结构型式,本文对低温恒温器热负荷来源进行了研究,包括低温绝热支撑(POST)、电流引线、高功率耦合器的热传导,80K冷屏的热辐射,超导腔、高功率耦合器的动态热负荷等。研究结果表明,CM4低温恒温器满足低热负荷的要求,为下一步低温恒温器的优化及运行调试提供了理论基础。
In order to optimize the structure of CM4 cryomodule, the sources of heat load of the cryomodule were analyzed, such as the heat conduction of POST, current leads and high power coupler, the heat radiation of 80 K shield, and the dynamic heat load of superconducting cavity and high power coupler. The results show that the CM4 cryomodule satisfies the needs of low heat load, and it provides important theory foundation of optimization and commissioning.
