摘　　要：用于冷却超导磁体的低温系统由管路、支管、阀门和泵等组成.在实际情况中,低温系统的暂态和稳态响应对磁体的性能有很大影响;同时磁体的暂态过程对低温系统也有影响,因此需要把低温系统和磁体系统作为整体来考虑以提高模型的预测能力.本文分别对两个具体实验装置的低温系统建立了简化模型,并对比了模拟计算结果与实验数据,结果表明模型能够较好地模拟超导磁体的低温系统.Cryogenic systems used for cooling superconducting magnets consist of pipes, manifolds, valves, and pumps, etc. As in practical situations the steady state and transient response of the cryogenic systems strongly affects the behavior of the magnets, and transient conditions in the magnets also affect the cryogenic systems, in order to improve the accuracy of prediction of the model, it is necessary to study the cryogenic and magnetic systems as a whole. In this paper, simple models of cryogenic systems for two practical experiment facilities were presented. The simulation results are roughly consistent with experimental results. This confirms the usefulness of the model on numerical study of cryogenic systems for superconducting magnets.
