1 GANIL - Grand Accélérateur National d'Ions Lourds

A new system has been designed to inject the 10 GHz rf power in the NANOGAN III ion source dedicated to the ionization of exotic atoms from the production target of the SPIRAL system at GANIL. The present system, based on a rectangular-to-coaxial transition equipped with a tuning piston, has been replaced by a direct rectangular-to-circular wave guide to feed the plasma of the source. We present the constraints related to the rf injection and a comparison is given of the present and new injection systems.
