Abstract :
The improved method of calculating intense helical electron beams based on assigning the initial velocity spread and finding functions of electron distribution over oscillatory and longitudinal velocities is presented. The methods of ensuring and testing the cathode emission homogeneity are discussed. The data obtained in numerical simulation modeling and experimental measurements for beams with various topologies and emitter properties are compared. The evolution of the function of electron distribution over oscillatory velocities as the beam current grows is traced.
