Development of Electron Sources for Modern and Future SR Sources and Colliders at the Budker Institute of Nuclear Physics of the Siberian Branch of the Russian Academy of Sciences

This work examines some properties of the formation of electron beams for modern SR sources and colliders. Trends in this area are described. Characteristic parameters of such sources for developed and designing accelerator facilities are discussed. Latest developments at the Budker Institute of Nuclear Physics, Siberian Branch, Russian Academy of Sciences, in the field of electron guns are described, as well as plans for the development of electron sources at the institute for possible future SR sources and colliders are given.
