METHOD OF GENERATING MULTI-VELOCITY NON-LAMINAR ELECTRON BEAMS Russian patent published in 2014 - IPC H01J3/02 

FIELD: physics.

SUBSTANCE: invention relates to microwave electronics and is intended for generating multi-velocity non-laminar electron beams. The method of generating an electron beam includes emitting electrons from a cathode, accelerating the electrons with an accelerating electrode with potential U₀ and decelerating the electrons. Deceleration is carried out using a grid with potential U₁<U₀, which overlaps part of the electron beam, resulting in spread of electron velocities in the electron beam.

EFFECT: increased spread of electron velocities in an the region of an electron gun through controlled deceleration of part of an electron beam, particularly its peripheral part.
