• heavy ions
• spread-out Bragg peak
• range modulator

A rotating range modulator designed and manufactured in IMP is introduced, which is applied to extend Bragg peak of heavy ion beam. With double ionization chamber method, Bragg curve of 75MeV/u C-12 ions and Modulated Bragg curves of 75MeV/u O-16 and 75MeV/u C-12 ions through this range modulator were measured respectively, and two evident spread-out Bragg peaks corresponding to the modulated beams above are shown. The calculated curves are also exhibited for comparison.
