MULTIGAN®: A new multicharged ion source based on axisymetric magnetic structure

Abstract : The regular ECR ion sources, allowing the production of multicharged ions, have openings only at their two ends. Based on the MONO1000 ECRIS [1] concept and experience, a new multicharged ECR ion source has been designed with a large opened space in the middle of the source enabling a direct contact with the ECR plasma. This source will combine the advantages of the axisymetric magnetic structures made only of permanent magnets with a high operating frequency. The magnetic structure calculations as the mechanical design and stress will be described in details. An estimation of the electronic energy distribution has been calculated using the TrapCad code [2] and thus the performances of the source have been deduced. A rough calculation of the beam extraction and formation has also been calculated taking into account of the several fields (magnetic and electric) surrounding the extraction system. The ion source presented in this paper is a prototype which shall validate the magnetic concept and which shall confirm the expected performances. The next step will be the design of an optimized ECRIS according to its future applications.
