Structure design and optimization analysis of proton beam window in target station for CSNS-II

  • 摘要: 中国散裂中子源(CSNS)靶站质子束窗位于环到靶站输运线(RTBT)与靶站交接面,起到隔离加速器高真空和靶站氦气环境的作用。随着束流功率提高,目前质子束窗单层膜结构形式已无法满足CSNS-II 500 kW的高功率需求,因此开展CSNS-II质子束窗研制,设计出双层膜中间通水的冷却结构,完成质子束窗双层膜的薄膜半径、薄膜厚度、水冷槽长度与宽度、对流换热系数等各参数对质子束窗温升与热应力的影响分析。通过冷却水需求分析得出,冷却水流速需大于15 L/min。通过质子束窗主体的流固耦合分析,消除箱体内部死水区域。最终优化后质子束窗薄膜位置最高温度47.8 ℃,薄膜位置最高热应力30.758 MPa。通过FLUKA软件对质子束窗材料的辐照损伤性能进行分析,在每年5000 h工作时长、500 kW高功率束流的辐照下,辐照损伤DPA计算值为1.285 DPA,质子束窗的安全使用寿命在7年以上。
