The demand for high charge states of exotic ions prior to their injection into an accelerator has driven the development of the charge breeding method. Existing facilities like REX-ISOLDE or ISAC at TRIUMF are already using a charge state booster for the post acceleration of radioactive ions. Planned facilities like MAFF, SPES, SPIRAL II and EURISOL have identified the need of a breeding system because of the demand for highly charged ions for low energy experiments and because of the available budget and space. Therefore the exploration and optimization of existing charge state breeders is mandatory and is supported by the I3EURONS and the EURISOL-DS. The Frankfurt MAXEBIS (MAX electron beam ion source) setup has been modified within the past years towards a charge state breeder including external injection of alkaline ions by a surface ionisation source. The electron gun, the inner electrode structure and the collector of the MAXEBIS have been modified. The charge breeding experiments will be done at GSI. The new setup and first experimental results will be presented.
