摘　　要：作为样品环境极端条件之一,中子散射超导磁体系统产生的强磁场为凝聚态量子材料等磁性前沿研究提供了理想的工具平台。对国内自主研制的第一台中子散射磁体关键部件——低温容器结构及制冷方式进行了介绍,对该方案的结构系统传热进行Ansys仿真模拟与分析,验证了结构的合理性;在传热模拟的基础上,对各部件进行了热负荷计算,完成了制冷机的选型。As one of extreme environmental condition for samples, high magnetic field of neutron scattering magnet system provides the ideal platform for condensed matter quantum material and other magnetic cutting-edge research. In this paper, structure and cooling way of cryostat as the most important part of superconducting magnet system for neutron scattering were presented. By heat transfer simulation of software Ansys, feasibility of cryostat structure was verified. After heat load calculation of every component, selection of cryo-refrigerator was completed.
