Abstrakt: An S-band linear accelerator (linac) equipped with a radio-frequency (RF) photogun with an operating frequency of 2.8 GHz is under development in the National Research Center "Kurchatov Institute." This linac will be used as a top-up injector for the storage ring of the SILA Ultimate Source of Synchrotron Radiation (USSR) and as a driver of high-brightness electron bunches for the free-electron laser (FEL). A pilot RF photogun for this linac injector is currently under development in the National Research Nuclear University "Moscow Engineering Physics Institute." The optimization of geometric parameters and the modeling of electrodynamic characteristics have been performed in an RF gun based on a 3.6-cell π-mode standing wave accelerating structure. Beam dynamics has been studied. In addition, the results from the analysis of thermal processes will be reported. The accelerating cavity design will also be presented. [ABSTRACT FROM AUTHOR]
