Abstract
A device for optimizing a source of ions with electronic cyclotronic resonance (ECR) is provided. The present invention comprises a conventional ECR source to which an apparatus is added for moving the resonance point (C) which appears in the dielectric pipe when the source is in operation. The controlled adjustment of the position of the resonance point (C) ensures an optimal positioning of points A and B of the equimagnetic surface, points (A) and (B) being dependent on point (C). The resonance displacement apparatus comprises, in one embodiment, a magnetic screw threaded onto its periphery so as to form a screw/nut system with the armouring of the ECR source. Particular utility is found in the area of particle accelerator equipment for use in scientific and medical applications, although other utilities are contemplated.
