摘要
随着技术的不断发展,近年来出现了多种加速器束团长度的测量方法,主要有条纹相机测量、迈克尔逊干涉仪测量、电光晶体测量、耦合束流频谱测量等。本文综合介绍了这些方法,并指出各种方法都有自己的优缺点及适用范围。目前国际上各大型加速器实验室普遍采用的是条纹相机测量方法,对于自由电子激光等超短束团一般都是采用光学技术、频域方法测量,有些测量法的分辨率可达到飞秒级,提供了具有更高空间分辨率、更高时间分辨率的强有力研究手段。
With the improvement of technology, many new accelerator bunch length measurement methods are in-vented in recent years, such as streak camera, Martin-Puplett interferometer, electro-optic detection, frequency do-main method. Each method has its respective advantages, disadvantages and applied domains. A review on various bunch-length measurement methods is given in this paper. At present many large accelerators in the world universally use streak camera to measure bunch length. For beam bunches of ultrasho...
