我们详细地测量了高亮度相对论电子束压缩到亚皮秒长度所引起的横向相空间扭曲。当光束被强压缩时，在相空间中观察到一个强分叉。利用几种计算模型对这种效应进行了分析，并将其与纵向相空间的折叠相关联。讨论了这些结果对当前弯曲系统中集束效应研究的影响，以及对未来短波长自由电子激光和线性对撞机的影响。
We report detailed measurements of the transverse phase space distortions induced by magnetic chicane compression of a high brightness, relativistic electron beam to subpicosecond length. A strong bifurcation in the phase space is observed when the beam is strongly compressed. This effect is analyzed using several computational models and is correlated to the folding of longitudinal phase space. The impact of these results on current research in collective beam effects in bending systems and implications for future short wavelength free-electron lasers and linear colliders are discussed.
