Status Report on Metallic Beam Production at GANIL/SPIRAL 2

Abstract : Primary ion beams from metallic elements are routinely produced at GANIL using ECR4 and ECR4M 'room temperature' ECR ion sources. Ionization efficiency measurements, partially presented in the past, are summarized in this report together with updated and new results obtained with Cd, Mo and Ta. Preliminary results for Ni and Ca obtained with the room temperature Phoenix-V2 ECR ion source, under commissioning for SPIRAL 2, are also included. These ionization efficiencies are compared according to the production methods: oven, sputtering, MIVOC, gaseous compounds. The presently SPIRAL 2 heavy ion injector designed for ions Q/A=1/3 shows clear limitations in terms of intensity for metallic ions with mass higher than 60 (intensity <1 pμA). In order to choose the best ion source for a future Q/A=1/6, 1/7 injector, best world results have been compiled for different existing 'room temperature' and superconducting ECR ion sources.
