Paper Abstract

The computer-aided design of gridded electron guns on a basis of two, two and half and 3D mathematical models is carried out. The parameters of cathode-grid assembly (CGA) are calculated, synthesis and the trajectories analysis of ungridded gun, in which a control grid is supposed to be established, are realized. The trajectories analysis of a beam in CGA cells is fulfilled, the coordinates, velocites and charges of large particles on an exit from CGA cells are used for definition of the initial data for solving beam motion equations in the gridded electron gun and further in magnetic focusing system. Electron-optical systems with gridded electron gun, designed with the help of this complex of codes, do not require experimental correction and provide good current permeability in microwave tubes.
