摘要
本文针对中国原子能科学研究院HI-13串列加速器升级改造项目中QWR(QuarterWave Resonator)超导腔低温系统进行了分析,模拟优化了超导腔稳定工作状态时所需的最佳氦流质量流量以及允许的波动范围,并考虑了氦流质量流量过小所产生的冷箱末级换热器冷端出口“负温差”和超导腔失超的问题,为实际工程提供一定的理论依据。
This article made specific analysis of the cryogenic system for QWR superconducting cavities used in China institute of atomic energy HI-13 linac upgrade. A model for calculating the optimum quantity of He and its fluctuating range when the QWRs are stable is developed. The ＂negative temperature difference＂ at the cold side of the last heat exchanger in cold box and the quench of the superconducting cavities caused by the deficient quantity of He are also considered. The results are presented as a theoretical reference to some extent for practical design.
