在文献[12]里已经根据各自的情况,用不同的方法独立导出了电子直线加速器圆对称系统考虑加速过程的粒子横向运动包络线方程。这对于解决象强流短脉冲电子直线加速器、电子直线感应加速器之类的横向运动问题是很有意义的。但是,在某些情况下,象质子直线加速器,螺旋波导直线加速器,中、高能电子直线 In [12], the equations of the lateral movement of particles in the linear symmetry system of electron linear accelerator considering the acceleration process have been independently derived according to their own situations and in different ways. This is of great significance to solve the problem of lateral motion such as strong pulse short pulse electron linear accelerator, electron linear accelerator. However, in some cases, such as proton linacs, helical waveguide linacs, medium and high energy electron straight lines
