Abstract

The possibility of implementing a previously proposed procedure for determining the beam dimensions at a target is analyzed; it includes the measurement of two-dimensional angular distributions of the coherent radiation of fast electrons for two distances between a crystal, where radiation is generated, and a coordinate detector. The use of two mechanisms of parametric X-ray radiation and diffracted transition radiation is considered. The limits of the method sensitivity and the influence of the departure of secondary electrons and photons on them are discussed.

关于测量纵向尺寸较小的相对论电子束的横向尺寸的程序的建议

摘要

分析了实施先前提出的确定目标光束尺寸的程序的可能性；它包括测量快电子的相干辐射在产生辐射的晶体与坐标检测器之间的两个距离上的二维角分布。考虑使用参数X射线辐射和衍射过渡辐射的两种机制。讨论了方法灵敏度的局限性以及二次电子和光子的离去对其的影响。
