Abstract

In the given work the experimental results of formation of the electron beam with a current up to 4 A in the electron gun with the cathode of a small diameter - 13 mm are presented. The gun is intended for generation of intense electron beams in systems of electron cooling used for fast and deep cooling of ions in the scheme with large factor of expansion in a decreasing magnetic field.
