Paper Abstract

The hollow electron beams in gyrotrons are normally generated in magnetron injection type (MIG) guns1. In these guns the transverse velocity of the electrons is mainly determined by the ExB-drift at the emitter. Non-adiabatic effects during the acceleration do not give a major contribution. Several properties of the electron beam, such as the sensitivity to space charge effects and to conditions of the emitter surface, are related to this kind of extraction.
