A room temperature home built 10 GHz ECR ion source delivers beams of B, C, N, O, F, Ne, S, Ar to the Cyclotron U200-P. The same ion source has also been used for surface irradiation of the solids. To upgrade the ion source and increase the ion current in the cyclotron an oven for evaporation of solid materials has been constructed and a two gap buncher has been installed in the injection line. Some new observations on the influence of the extraction system on the ion beam current will be presented.
