Abstract

In a magnetic system for gyrotrons, a permanent magnet arrangement is provided including a central radially polarized magnet, and axially polarized annular magnets disposed at opposite end faces of the central magnet and indirect contact therewith, the magnets are structured in the resonator area to provide a predetermined magnetic field which has its field reversal only in the axial extension of the gyrotron outside the emitter area where it does not affect the electron beam generated by the emitter.
