Abstract (en)
Device for optimising an electron cyclotron resonance (ECR) ion source. The invention consists in adding, to a conventional ECR source, means of shifting the point of resonance C which appears in the dielectric duct 23 when the source is working. The optimal adjustment of the position of the point C ensures optimal positioning of the points A and B of the equimagnetic surface 13, these points A and B being dependent on the point C. These means of shifting include a magnetic screw 47 threaded on its periphery so as to form a screw/nut system with the armour 11 of the ECR source. This device finds numerous applications especially in particle accelerator equipment used in the scientific and medical sectors. <IMAGE>
