研究了相对论带电粒子在射频直线加速器中的横向运动。导出了粒子在周期加速腔系统中的空间平均运动方程，并在超相对论极限下精确求解。这些解决方案，沿着脉冲处理的瞬态在入口和出口的直线加速器腔，允许推导出一个线性传输矩阵通过腔。这个广义矩阵是改进了以前得出的结果，它是适用于行波和驻波结构，允许任意注入相位和空间谐波内容的射频场，更准确地近似精确的带电粒子运动。
The transverse motion of a relativistic charged particle in a radio-frequency linear accelerator (rf linac) is examined. The spatially averaged equations of motion are derived for a particle in a periodic accelerating cavity system, and solved exactly in the ultrarelativistic limit. These solutions, along with an impulse treatment of the transients at the entrance and exit of the linac cavities, allow derivation of a linear transport matrix through the cavity. This generalized matrix is improved over previously derived results in that it is applicable to both traveling- and standing-wave structures, allows for arbitrary injection phase and spatial-harmonic content of the rf fields, and is more accurate in approximating the exact charged-particle motion.
