CHARGED PARTICLES ACCELERATION METHOD AND LINEAR ACCELERATOR Russian patent published in 2023 - IPC H05H9/04 

FIELD: nuclear physics.

SUBSTANCE: physics of charged particle acceleration processes. A method for accelerating charged particles by an electric field wave having a coherence front such that a set of wave elements with identical phases forms an axisymmetric surface is characterized by forming a wave with a coherence front forming a conical surface and directing it to the accelerator axis so that the intersection point of the conical front of the coherence of the accelerating wave with the axis of the accelerating structure was close to or higher than the speed of the accelerated particles. In the cut plane passing through the axis of the accelerator, the path traversed by the accelerated beam along the axis of the accelerator during the period of the field change and the path traversed by the accelerating field wave when it moves towards the axis of the accelerator during the period of the field change are equal and form a triangle, the third side of which is the section line of the accelerating field wave of the coherence front of this field. In this case, the angle between the direction of the radially converging wave front of the accelerating field and the direction of acceleration of charged particles is greater than 90°, the generated wave is crossed with the axis of the accelerator more than once. The linear charged particle accelerator additionally contains a device for forming an accelerating wave with a coherence front turned relative to the direction of wave movement, which contains an annular horn in the form of a bell, a corrective lens forming a metal plate or dielectric lens, a device for turning an annular directional wave.

EFFECT: simplification of the design, expansion of the technical capabilities of linear accelerators and their areas of application.
