采用５０μｍ厚聚碳酸酯薄膜、利用核径迹探测技术测得φ４０ｍｍ的２５ＭｅＶ／ｕ４０；Ａｒ１４；离子束的均匀度在散焦情况下为３２．７％，在“散焦＋样品旋转”情况下为５２．４％。还采用多层聚碳酸酯薄膜组件作为肿瘤块等效材料，进行了重离子束治癌束流成形模拟试验，通过对２５ＭｅＶ／ｕ４０；Ａｒ１４；离子束９个间隔的降能来移动其Ｂｒａｇｇ峰位，并在各个峰位上经过光阑赋予不同的束流截面，由不同层面上的截面可以构成一肿瘤块的椭球状。利用这种方法辐照聚碳酸酯薄膜组件，经化学蚀刻处理后，利用离子径迹小孔对普通光柱的透射与衍射，得到了类似于椭球形肿瘤的光球，光球范围就反映了重离子束能损集中的Ｂｒａｇｇ峰作用的部位。
Using 50μm thick polycarbonate film, using nuclear track detection technology φ40mm 25MeV / u40; Ar14; ion beam uniformity is 32.7% in the defocus case, in the “defocus + sample rotation” case For 52.4%. A multi-layer polycarbonate film assembly was also used as an equivalent material for the tumor mass. The beam-forming simulation test of heavy ion beam cancer was carried out. The Bragg peak was shifted by lowering the energy of 25MeV / u40; Ar14; Bit, and at each peak position through the aperture to give a different beam cross-section, the cross-section of the different levels can form a tumor mass ellipsoid. Using this method of radiation polycarbonate film assembly, the chemical etching process, the use of ion trajectory holes on the ordinary beam transmission and diffraction, obtained similar to the ellipsoid tumor photosphere, the sphere of light reflects the weight of the heavy The ion beam can damage the site of the concentrated Bragg peak.
