摘要:

高亮度电子加速器(诸如能量恢复直线加速器(ERL))通常具有复杂的粒子分布,这可能在束传输以及与诸如用于从束产生辐射的摆动器的装置匹配方面产生困难。光学渡越辐射(OTR)、光学渡越辐射干涉术(OTRI)和光学衍射-渡越辐射干涉术(ODTRI)已被证明是诊断带电粒子束空间和角分布的有效工具。OTRI和ODTRI已被用来测量均方根发散和光学横向相空间映射已被证明使用OTRI。在这项工作中,我们提出了使用OTR和ODR在杰斐逊实验室115兆电子伏ERL进行的诊断实验的结果,其中显示存在两个单独的组件内的空间和角分布的光束。通过假设空间和角度特征之间的相关性,我们估计两个分量中的每一个的均方根发射度值。

英文摘要:

High brightness electron accelerators, such as energy recovery linacs (ERL), often have complex particle distributions that can create difficulties in beam transport as well as matching to devices such as wigglers used to generate radiation from the beam. Optical transition radiation (OTR), OTR interferometry (OTRI) and optical diffraction-transition radiation interferometry (ODTRI) have proven to be effective tools for diagnosing both the spatial and angular distributions of charged particle beams. OTRI and ODTRI have been used to measure rms divergences and optical transverse phase space mapping has been demonstrated using OTRI. In this work we present the results of diagnostic experiments using OTR and ODR conducted at the Jefferson Laboratory 115 MeV ERL which show the presence of two separate components within the spatial and angular distributions of the beam. By assuming a correlation between the spatial and angular features we estimate an rms emittance value for each of the two components.
