We report on the experimental generation of a train of subpicosecond electron bunches. The bunch train generation is accomplished using a beam line capable of exchanging the coordinates between the horizontal and longitudinal degrees of freedom. An initial beam consisting of a set of horizontally separated beamlets is converted into a train of bunches temporally separated with tunable bunch duration and separation. The experiment reported in this Letter unambiguously demonstrates the conversion process and its versatility.
我们报告了亚皮秒电子束列的实验产生。通过使用能够在水平和纵向自由度之间交换坐标的束线来实现束列的产生。由一组水平分离的束流组成的初始束流被转换成具有可调谐束流持续时间和间隔的束列。本信中报告的实验明确地证明了转换过程及其多功能性。
