Title: Radio frequency injection system for electron-cyclotron-resonance ion source in a hostile environment

Abstract

In the framework of the Systeme de Production d'Ions Radioactifs Acceleres en Ligne Phase II (SPIRAL II) project, one of the ion sources which produce 1+ ions is an electron-cyclotron-resonance ion source (ECRIS). The source is installed in a region where the dose rate is such that the radiation hardness is very important for the materials used. Moreover, the proximity of the UC{sub x} target leads to additional constraints as potential surface pollution. A radiation-hard ECRIS has been designed, and the rf injection is under study. The results of rf injection with a wave guide and with an antenna will be presented. The performance obtained with both injection systems combined with the environmental constraints have led us to inject the rf using an antenna. The last point consists in designing a wave guide able to transport the rf through the shielding of the SPIRAL II plug. Design constraints, tests, and the current state of the project will be presented.
