Description

technical field [0001] The invention relates to a guided magnetic field system, in particular to a radial non-foil diode guided magnetic field system in the combined focusing mode of a permanent magnet ring and a helical disk. Background technique [0002] In the development process of high-power microwave sources, high power, high frequency, high efficiency and miniaturization have become the development direction of most high-power microwave sources. Under the same beam current, the radial electron beam generated by using a foil-free diode with a larger emission cross-section has lower beam current density and space charge effect, which can reduce the intensity of the guiding magnetic field while obtaining higher beam conversion efficiency It is beneficial to achieve high efficiency and miniaturization of the system, and can avoid the problems of electron beam scattering and decrease of the transmission rate caused by the electron beam penetrating the anode net.
