La chambre possde une source de champ magntique et une source de rayonnement lectromagntique. In electron cyclotron resonance ion sources, the ions are formed by strongly ionizing a gas or a vapour of a solid contained in an ultra-high frequency cavity, as a result of the combined action of a high frequency electromagnetic field established in the cavity and a resultant magnetic field prevailing in said cavity. Ion cyclotron resonance occurs when ions rotating in a magnetic field are resonated by external electric field. Ions in these sources are created and extracted from a plasma produced by ECR discharge in a usually very strong B-minimum type magnetic trap. Optimization of an Electron Cyclotron Resonance Ion Source (ECRIS) to produce high currents of high charge state ions is typically a trial and error process. Electron cyclotron resonance (ECR) ion sources (ECRIS) [ 1, 2] deliver variously charged ion beams for direct applications and, more frequently, highly-charged ions worldwide for high energy accelerators.
