BETATRON WITH SIMPLE EXCITATION Russian patent published in 2012 - IPC H05H7/04 H05H11/04 G01V5/12 

FIELD: electricity.

SUBSTANCE: betatron magnet contains two guidance magnets with pole tips and gap in-between, core with gap, primary coil, orbit control coil, voltage pulse scheme and electron accelerator channel. Orbit control coil has section of compression coil slipped on around core gap and section of shifting coil slipped on around pole tips. Section of compression coil and section of shifting coil are connected in series with opposite polarity. The area limited by primary coil and shift coil is divided into core section and guidance magnet section and the boundary between them there is compression coil. Method for X-rays generation contains stages of flow generation by shift coil, formation of the first magnet flow, excitation of clamp coil, excitation of primary coil and injection of electrons at minimum intensity of the first magnet flow. Then the second magnet flow of opposite polarity is generated to compression of injected electron orbit up to optimal orbit, acceleration of electrons, polarity inversion of the second magnet flow when the first magnet flow reaches maximum intensity to expand electron orbit and collision of electrons with target , which leads to X-rays emission.

EFFECT: invention allows improvement in control efficiency of electron flow orbit.
