交叉杆漂移管直线加速器(CH-DTL)是一种非常优异和前沿的加速结构,其常温低能加速结构的分路阻抗很高,可运行于连续波模式,是未来ADS等强流CW加速器的重要备选加速结构之一。针对交叉杆漂移管直线加速器腔体的电磁场进行了模拟计算,提出了约束变量参数扫描的腔体优化方法,提出的球形漂移管简化了机械加工的复杂度。图1为约束变量参数扫描与常规扫描
Cross-bar drift tube linear accelerator (CH-DTL) is a very excellent and cutting-edge acceleration structure, its room temperature low energy acceleration structure of the shunt impedance is high, can run in continuous wave mode, is the future of ADS and other high-intensity CW accelerator One of the important alternative acceleration structures. Aiming at the electromagnetic field of the linear accelerator cavity of the cross-bar drift tube, the cavity optimization method of parametric scanning with constraint variables is proposed. The proposed spherical drift tube simplifies the machining complexity. Figure 1 is a constraint variable parameter scanning and conventional scanning
