A concept for a charge state multiplier, to be used for the production of energetic radioactive ion beams based on the ISOL+ post-accelerator system, is discussed. The charge state breeder implies external ion injection into an electron beam ion source (EBIS). The total efficiency, measured by injecting a low-energy nitrogen (Q = 1+) beam, reached 14.5% and was essentially constant for confinement times up to 200 ms.
