Fast range adaptation is essential for three dimensional (3D) beam tracking for precise irradiations of moving targets with scanned ion beams. Electromagnetically controlled ion beam deflection in combination with a fixed absorber inside an ion beam delivery system has been considered as a fast range adaptation method for moving targets. As a feasibility test of this method, ion beams were deflected with magnets on a static wedge degrader at a thickness corresponding to the required range adaptation. Beam profiles at target position were investigated both in experiments and simulations. The measured horizontal and vertical beam profiles of 5-11 mm FWHM for specified range shifts of up to ±15 mm water equivalence were found to be in good agreement with simulations. © 2009 Springer-Verlag.
