A SASE-FEL [A.M. Kontradenko和E.L. Saldin，Particle Accelerators 10（1980）207; R.博尼法西奥角佩莱格里尼和I.M. Narducci，Opt. Commun. 50（1884）373]要求极高的高峰电流，这是电子枪所不能达到的。因此，束长度必须沿加速直线加速器沿着减小，束必须被压缩。在TTF-FEL中，这是在三个阶段中借助于偏转磁体弯道来完成的。我们提出的布局的计划，以及第一束动力学计算。
A SASE-FEL [A.M. Kontradenko and E.L. Saldin, Particle Accelerators 10 (1980) 207; R. Bonifacio, C. Pellegrini and I.M. Narducci, Opt. Commun. 50 (1884) 373] requires extremely high peak currents which cannot be achieved by electron guns. The bunch length therefore has to be reduced along the accelerating linac, the bunch has to be compressed. In the TTF-FEL this is done with the help of bending magnet chicanes in three stages. We present the lay-out of the scheme as well as first beam dynamics calculations.
