Abstract (en)

[origin: US4563615A] An electron gun of the type comprising two electrodes facing each other and brought to different potentials so as to create therebetween a continuous electric field and a cathode positioned in the extension of the electrode at negative or zero potential and brought to the same potential as this latter, the assembly being subjected to a magnetic field perpendicular to the electric field. In the plane perpendicular to the magnetic field, at least one of said electrodes has a divergent profile so that the distance between electrodes increases from the cathode towards the outside of the gun.
