Abstract:
1. A DC voltage-operated particle accelerator for accelerating a charged particle from a source to a target, comprising: a first electrode arrangement, and a second electrode arrangement separated from the first electrode arrangement, wherein the first electrode arrangement and the second electrode arrangement are arranged such that the particle travels through the first electrode arrangement and the second electrode arrangement in chronological succession, wherein each of the first and second electrode arrangements is formed as a high-voltage cascade, wherein each of the first and second electrode arrangements comprises multiple concentrically arranged metal half-shells that define capacitor plates of the high-voltage cascade, wherein a radially innermost half-shell of each electrode arrangement has a greater electrical potential difference with respect to a ground potential than each other half-shells of that electrode arrangement, and wherein the first electrode arrangement is configured to have a first potential generated inside it and the second electrode arrangement is configured to have a second opposite potential generated inside it.
