【摘要】 Spoke型射频超导(SRF)加速腔水平测试低温恒温器是中国科学院先导专项加速器驱动次临界系统(ADS)项目的重要设备之一,水平测试成功与否,直接影响到超导腔、耦合器、调谐器等能否带束流运行。对水平测试恒温器的功能及工作流程进行了初步分析,通过对恒温器中部分关键部件结构及热力学分析,以及不同温区热负荷模拟分析研究,确定恒温器的结构形式,同时为恒温器的低温测试和运行的稳定性提供理论依据。更多还原

【Abstract】 Horizontal test cryostat of Spoke type superconducting radio frequency( SRF) cavity is one of key devices in the ADS project,which has direct effect on the running of the SRF cavity,power coupler and tuner with beam. The function and working flow chart of the cryostat was described,through the structure and thermodynamic analysis of the key parts,heat loads simulation at different temperature,the structure of the cryostat was final determined and the theoretical basis was provided for next cryogenic test and operation.更多还原
