标题： Overview of non-intercepting beam-size monitoring with optical diffraction radiation

摘要： 近年来，关于使用光学衍射辐射（ODR）作为非拦截性电子束参数监测器的初步演示被回顾。 讨论了由带有狭缝孔径的金属平面、单个金属平面以及双平面干涉产生的ODR在远场成像和近场成像方面的进展。 还将讨论偏振效应以及对束团尺寸、发散度和位置的灵敏度，并提出了一种在25 GeV下监测10微米束团尺寸的路径。 显示英文摘要

摘要： The initial demonstrations over the last several years of the use of optical diffraction radiation (ODR) as non-intercepting electron-beam-parameter monitors are reviewed. Developments in both far-field imaging and near-field imaging are addressed for ODR generated by a metal plane with a slit aperture, a single metal plane, and two-plane interferences. Polarization effects and sensitivities to beam size, divergence, and position will be discussed as well as a proposed path towards monitoring 10-micron beam sizes at 25 GeV.
