Status report on ECR ion source operation at GANIL

Two electron cyclotron resonance ion sources, ECR 4 and ECR 4M, provide high chargestate beams to the compact cyclotrons, C01 and C02, which are alternative injectors for theGANIL cyclotrons CSS1 and CSS2. When an injector runs for a long period, the off-linesource can be used for beam developments or, together with the off-line injector, deliver abeam to a new beam line, called IRRSUD, for atomic physics experiments. Various ions arerequested for beam time for periods of 8 to 11 weeks. Although the majority of the requiredbeams comes from gaseous elements, work on the production of beams of metallic ions isalways a main activity. New ovens are being developed to improve the capacity and theperformances of the standard micro-oven. The latest results with 238U beam , usingsputtering method and 76Ge beam using recycling method are reported here
