Description
A rotating range modulator was designed and manufactured, which is applied to extend Bragg peak of heavy ion beam. Bragg curves of 75 MeV/u 16O and 75 MeV/u 12C ion beams through this range modulator were measured respectively and two evident spread-out Bragg peaks corresponding to the modulated beams above are shown. In addition, inactivation effect of the modulated 75 MeV/u 16O ion beam at nine different penetration depths on melanoma cells (B16) was measured. Results indicate that lethal effects at the spread-out Bragg peak region are larger than at the plateau of the particle beam entrance
