Abstract

A simple nonperturbing technique for the electron relativistic bunch diagnostics has been proposed which does not require the use of an interferometer for spectral measurements. The interferometer functions are performed by a slit target in which diffraction radiation is generated. The measurements of electron bunch length are carried out by shifting one half of the target relative to the other. A good agreement with the results of measuring the coherent radiation spectrum of relativistic electron bunches has been obtained.

基于相干衍射辐射的电子束长度无扰测量方法

摘要

已经提出了一种用于电子相对论束诊断的简单的非干扰技术，该技术不需要使用干涉仪进行光谱测量。干涉仪的功能由产生衍射辐射的狭缝靶来执行。电子束长度的测量是通过将靶材的一半相对于另一半进行位移来进行的。已经获得了与相对论电子束相干辐射光谱的测量结果很好的吻合。
