摘　　要：为满足强流加速器对准直器高散热性能、高抗辐射性能、超高真空、高定位精度、高稳定性和在线实时调整等特殊要求,在CSNS/RCS主准直器设计时针对结构方案和控制方案进行了详细设计和研究,针对关键部件:刮束器、真空盒、驱动装置和远程快速拆卸装置等设计难点进行了阐述,在设计中使用ANSYS完成了刮束器的热分析及支架强度和变形校核,用FLUKA程序对辐射屏蔽进行了分析和设计,确保主准直器设计的可靠性。In order to meet special requirements of tile high intensity accelerator for collimators with good heat dissipation performance, radiation protection performance, uhra high vacuum, high positioning accuracy, high stability, and online real time adjustments, researches have been done for the primary collimator of rapid cycling synchrotron of China Spallation Neutron Source （CSNS/RCS）. To ensure the reliability of design for the CSNS/RCS primary collimator, the technical difficulties of the key con〉 ponents, such as the scraper, vacuum chamber, driving system and remote clamp are also discussed. Thermal analysis of the scraper and structure analysis of support parts have been completed by using ANSYS code. Radiation shielding is simulated with FI.UKA program.
