Abstract:

Mechanism for producing cusp magnetic field is studied. The physical model of cusp magnetic field has been set up with the amendment of the Moster-Molnar model. Based on the cusp magnetic field theory analysis and numerical simulation, factors that influence the cusp magnetic field design have been discussed. The Lagrangian formulation is used to solve the electron trajectories in some simple magnet ic cusp configurations. The relationship between the cusp magnetic field and the large orbit gyrotron hollow cusp electron gun has been explored, and some general conclusions have been presented on the prospects of generation and improvement of the big orbit cusp electron gun.

Key words: Electron gun, Large orbit gyrotron cusp electron gun, Cusp magnetic field
