Description
High-brightness light sources are of great interest nowadays. The fourth-generation light source SYLA (SYnchrotron+LAser) is one of the most significant facilities under construction in Russia. NRNU MEPhI designs the injector linac for SYLA. In order to present a high-quality radiation spectrum, a thorough investigation of electron beam parameters is necessary.
This study presents an analysis of the spectral-angular characteristics of the photon flux at the output of the first regular section of the linear accelerator designed for the SYLA light source. The impact of electron bunch dynamics on the parameters of the transition and the micro-undulator radiation is investigated. The bunch parameters at the output of the first linac regular section are examined using realistic particle distributions obtained by the prototype of the RF photogun. An analysis is conducted to explore the relationship between the energy and spatial parameters of the electron bunch and the resulting radiation flux parameters.
