摘　　要：本文分析了几种典型中子源低温氢系统的流程,结合各自的特点,重点讨论了三种氢循环方式,并对比了三种循环模式的优缺点。针对拟建设的中国散裂中子源(CSNS)低温系统,建议采用超临界氢循环,并在此基础上提出CSNS超临界氢循环低温系统的流程设计方案,为后续各项工作的开展提供理论基础。Some typical processes of cryogenic hydrogen system of neutron sources are analyzed in this paper. Emphasis is focused on three circulation modes of hydrogen in combining with the features of each cryogenic system, and the advantage and disadvantage of these modes are compared as well. Based on the cryogenic system of Chinese Spallation Neutron Source （CSNS） which is under construction, supercritical hydrogen loop is suggested. Design program of CSNS supercritical hydrogen loop is proposed, which is a theory foundation for the future work.
