ELECTRON-CYCLOTRON-RESONANCE ION-SOURCE DEVELOPMENTS AT LOUVAIN-LA-NEUVE

A new 6 GHz electron cyclotron resonance (ECR) ion source has been dev eloped and installed at Louvain-la-Neuve. It replaces the previous ECR ion source OCTOPUS and routinely produces highly charged ion beams fr om gaseous elements with a better intensity and stability. The magneti c configuration of the ion source and results obtained for the product ion of gaseous (O,Ar,Xe) and metallic (Ni) ions are presented. The pos sibility to use the sputtering method to ionize radioactive elements h as been tested on F-18(T-1/2 = 110 min). Ionization efficiency measure ments for F-18(1+) are reported.
