Abstract

According to synthesis of the formation electron beams

the general solutions of space-charge flow and electrode shape are derived in the crossed electric and magnetic fields electrode system in which the cathode operates under arbitrary condition. Characteristics of some magnetron injection guns and crossed-field guns

which are based on the general solutions

are calculated and analysed

The effects of the cathode surface electric field intensity and electron initial velocity on electron trajectories and electrode shapes are discussed.
