| Abstract: | 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 12 C ions and Modulated Bragg curves of 75MeV/u 16 O and 75MeV/u 12 C 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. |
