Abstract

The gas mixing effect in the electron cyclotron resonance (ECR) multicharged ion sources is analyzed while taking into account the ionization cross sections of different support gases such as H₂, He, Ne, N₂, and O₂. The Ar⁹⁺ ion currents delivered by a CAPRICE ECR ion source are measured as a function of the support gas pressure. The efficiency of ionization of these different gases by electron impact may partially explain the improvement of the extracted Ar⁹⁺ ion current.
