Abstract
Some physical principles and design solutions that were used in the creation and modernization of electron sources with grid plasma emitters and which made it possible to improve their parameters and operational properties are considered. As an example, the main characteristics of modernized low-energy (up to 25 keV), medium-energy (up to 100 keV) and relatively high-energy (up to 200 keV) electron sources with grid plasma emitters are given, which are distinguished by a unique set of basic parameters, which allows them to be used both in scientific, and for technological purposes. The prospects for further development of such sources are shown and the scope of their application is considered.
