Abstract
A cascade accelerator (1), with two sets (2, 4) of capacitors (26, 28) which are each connected in series, interconnected by diodes (24, 30) in the form of a Greinacher cascade (20), is to have in a compact construction a particularly high attainable particle energy. Therefore, the cascade accelerator has an acceleration channel (8) which is formed through openings in the electrodes of the capacitors of a set (2), directed to a particle source (6) arranged in the region of the electrode with the highest voltage (12), wherein the electrodes are insulated to each other apart from the acceleration channel (8) with a solid or liquid insulation material (14).
Claims20
A cascade accelerator comprising two sets of respectively series-connected capacitors connected up via diodes in the manner of a Greinacher cascade, and an acceleration channel formed by openings in the electrodes of the capacitors of a set and directed at a particle source arranged in the region of the electrode with the highest voltage, the electrodes being insulated from one another, except for the acceleration channel, by a solid or liquid insulating material.
A beam therapy device having a cascade accelerator comprising two sets of respectively series-connected capacitors connected up via diodes in the manner of a Greinacher cascade, and an acceleration channel formed by openings in the electrodes of the capacitors of a set and directed at a particle source arranged in the region of the electrode with the highest voltage, the electrodes being insulated from one another, except for the acceleration channel, by a solid or liquid insulating material.
