  • Device and method for optimizing diffusion section of electron beam
    Patent number: 9767985
    Abstract: Provided is a device for optimizing a diffusion section of an electron beam, comprising two groups of permanent magnets, a magnetic field formed by the four magnetic poles extending the electron beam in a longitudinal direction, and compressing the electron beam in a transverse direction, so that the electron beam becomes an approximate ellipse; another magnetic field formed by the eight magnetic poles optimizing an edge of a dispersed electron-beam bunch into an approximate rectangle; by controlling the four longitudinal connection mechanisms so that the upper magnetic yoke and the lower magnetic yoke of the first group of permanent magnets move synchronously towards the center thereof thereby longitudinally compressing the electron beam in the shape of an approximate ellipse, and the upper magnetic yoke and the lower magnetic yoke of the second group of permanent magnets move synchronously towards the center thereof thereby longitudinally compressing the electron beam in the shape of an approximate rectangl
