The Axially Modulated, Cusp-Injected, Slowly Varied Section Opened Cavity, Magnicon Amplifier

Abstract

I introduce a novel hybrid microwave amplifier that utilizes the axial bunching mechanism of klystrons in conjunction with the energy extraction mechanism of cyclotron resonance masers on TM mode. A simpler analytic model is used to show the viability of the device configuration and to explore limitations of the scheme. An example of an 11.5 GHz, fourth harmonic amplifier is presented. Adopting a multi-particle in azimuth range of (0, π/2) whose divide thickness of beam into three share approach, numerical simulation are used to demonstrate bunching in physical space and to estimate system efficiency et al. It shall be shown that this configuration enables the design of eficient, high harmonic devices over a wide range of parameters. Magnicon [1]-[11] is a kind of microwave amplifier tabe, it operates on the mode of rotating En10 in cylindrical cavity and there is solid focus fine electrons beam. In it from theory, the paper researches the new type magnicon, it is changed into using annular electron beam and using slowly variable section opened cavity. Compared with magnicon, its pervence beams will may be increased, its frequency may be increased up to millimeter wave band, its bandwidth also will may be increased same times. Than model of new type magnicon is put forward. Starting from large signal's theory, interacting of the annular electron beam into driver cavity in between the mode of rotating En10, numerical value to simulate. It done on the small current density and small density of electron in space that electrons dynamic are simulated, which may uses Runge-Kutta method to do it.
