展宽重离子束的Bragg峰
Extending of the Bragg Peak of Heavy lon Beam
【摘要】 介绍了自行设计加工的用于对重离子束Ｂｒａｇｇ峰进行展宽的旋转式射程调制器。实验上运用双电离室法测定了７５ＭｅＶ／ｕＣ离子束的Ｂｒａｇｇ曲线以及经该射程调制器调制的７５ＭｅＶ／ｕＯ及Ｃ离子束的Ｂｒａｇｇ曲线，调制的离子束嵳故境雒飨哉箍淼模拢颍幔纾绶澹⒔饬拷峁扑憬峁辛吮冉稀
【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.
