我们表明，列车的亚皮秒电子微聚束，与亚皮秒的间距，可以通过放置在一个区域中的束线的光束横向尺寸占主导地位的相关能量扩散的掩模。我们表明，微聚束的数量，长度和间距可以通过控制光束和掩模的参数。这种微聚束串可以进一步压缩和加速，并可应用于自由电子激光器和等离子体韦克菲尔德加速器。
We demonstrate that trains of subpicosecond electron microbunches, with subpicosecond spacing, can be produced by placing a mask in a region of the beam line where the beam transverse size is dominated by the correlated energy spread. We show that the number, length, and spacing of the microbunches can be controlled through the parameters of the beam and the mask. Such microbunch trains can be further compressed and accelerated and have applications to free electron lasers and plasma wakefield accelerators.
