- Abstract
The paper presents results of investigation into the special features of physics of fore-vacuum plasma sources of ribbon electron beams. The main difficulties encountered in the development of sources of this type are demonstrated. Conditions that allow one to increase the emission current density with simultaneous preservation of high degree of beam current homogeneity are determined. On the basis of the described physical features in the fore-vacuum plasma sources operation, the main directions in the development of the electron sources generating beams in the fore-vacuum pressure range are proposed.
