4 1 引言为实现X射线激光，一个强有力的候选者是基于自放大自发辐射（SASE）的高单程增益自由电子激光器。已提出几个方案用直线加速器组建这种装置。在短波长区自放大自发辐射自由电子激光器（SASE-FEL）需要高强度、高质量电子束和一个长的摆动器。关于SASE已经在理论上和模
4 1 Introduction One of the most powerful candidates for realizing X-ray lasers is the high gain one-way gain free-electron laser based on self-amplified spontaneous emission (SASE). Several proposals have been made to build such a device with a linear accelerator. Self-amplified spontaneous emission free-electron lasers (SASE-FELs) in the short wavelength region require high intensity, high quality electron beams and a long oscillator. SASE has been theoretically and modal
