The electron gun producing the precision hollow
relativistic electron beam for coherent microwave
generator applications has been developed and tested. It
is based on the large non-adiabatic compression of the
beam emitted by ring-shaped cathode with an active
surface big enough to produce a wanted current level.
Further improvement of beam quality is possible by
decreasing of the width of the annular emitter and
increasing its emissive power.
