Problems solved by technology

With the continuous growth of clustering, the space charge density of clustered electron beams is also increasing, and its space charge repulsion continues to increase. In addition, the space repulsion between electrons is superimposed, and the transmission of electron beams will become chaotic. Disorder, electron bombardment to the metal surface causes radio frequency breakdown to generate plasma, which affects the energy exchange with the intrinsic mode field, thereby reducing the working efficiency of the device

Abstract

The invention discloses a light periodic magnetic field coil applied to a high-power microwave source, the high-power microwave source comprises a radial transit time oscillator, and the periodic magnetic field coil comprises a plurality of magnet exciting coils which are uniformly arranged on the outer wall of a beam wave interaction area of the radial transit time oscillator at intervals; each excitation coil comprises multiple layers of densely wound solenoids oppositely arranged on the two sides of the outer wall of the beam-wave interaction area, the solenoids located on the same side of the beam-wave interaction area are linearly arranged, and an insulator is arranged between every two adjacent solenoids located on the same side of the outer wall of the beam-wave interaction area; superposed magnetic fields B (r) generated in the electron beam channel of the beam wave interaction area after the solenoids are electrified are in cosine distribution; wherein the peak value B0 of the superimposed magnetic field is times of the Brillouin magnetic field Bb of the electron beam under the corrected relativistic condition, and the magnetic field parameter alpha of the superimposed magnetic field B (r) is 0-0.66 or 1.72-3.76. On the premise of ensuring the stable transmission of the radial high-current relativistic electron beam, the weight of the external magnetic field coil can be reduced.

Description

technical field [0001] The invention belongs to the field of vacuum electronics, and more specifically relates to a lightweight periodic magnetic field coil applied to a high-power microwave source. Background technique [0002] High-power microwave technology refers to the generation, transmission, measurement and application of electromagnetic waves with an output power of 100MW to 100GW and a frequency of 100MHz to 100GHz. High-power microwave sources generate microwaves from the energy exchange between an intense relativistic electron beam and eigenmode fields in a high-frequency structure. The microwave source is the core of the high-power microwave system. Its front stage is the pulse drive source, and the latter stage is the mode conversion and radiation antenna. High-power microwaves have applications in many fields, such as directed energy, electronic countermeasures, and plasma heating. In order to meet the application requirements in these fields, the miniaturiz...
