Recycling effect of germanium on ECR ion source

Abstract

After running for three weeks with a 76Ge beam provided by the ECR-4 ion source at GANIL we have investigated the recycling effect of an SF6 plasma. The initial beam was produced by the classical method, using germanium dioxide in our micro-oven and helium as support gas. The overall ionization efficiency was measured and found to be around 3%. Without the oven, and using SF6 instead of helium, the ECR-4 ion source has been able to produce a very stable beam during a two-week period. The intensity of 76Ge13+ (enrichment 88%) was increased to 40 eμA, and the overall ionization efficiency reached 40%. The oven method of production, the recycling effect and perspectives are described in this paper.
