摘要
准确计算分析低温杜瓦的漏热量是评价低温杜瓦性能的重要依据。以一台自制的超导腔低温垂直测试液氦杜瓦作为研究对象,对其进行详细介绍,并进行了详尽的漏热计算。将计算结果与实测数据进行了对比分析,得到了该类型测试杜瓦产生漏热的原因,并给出了优化建议。
Heat losses analysis of the cryostat in a cryogenic envelope has great reference value to evaluate its cryogenic insulation performance. This paper analysed the heat losses of the vertical testing dewar of ADS LINAC in the condition of liquid helium and introduced the construction of dewar. Compared with the measured data, the actual cryogenic performance of the cryogenic dewar was further analyzed and the optimisation suggestion of this kind of cryogenic dewar was provided.
