单位长度上对带电粒子的最大可能的加速能力是直线加速器应用的一个最重要的指标。边耦合驻波加速结构具有高分路阻抗、高稳定性等一系列优点。我们知道,低能行波型电子直线加速器,采用射频反馈或小的耦合孔方法固然能减小加速器体积。但前者使系统复杂化;而后者将使束流通过增加困难。近十年来,有关边耦合腔结构驻波电子直线加 The maximum possible acceleration per unit length of charged particles is one of the most important indicators of linear accelerator applications. Side coupling standing wave acceleration structure with a high shunt impedance, high stability and a series of advantages. We know that low energy traveling wave linear accelerator, using RF feedback or a small coupling hole method can certainly reduce the accelerator volume. But the former complicates the system; the latter will make the beam flow more difficult. In the past ten years, the side coupling cavity structure standing wave electron straight line plus
