    • Some embodiments of the present invention provide apparatus for detecting particles of radiation comprising: a plurality of solid state semiconductor detector devices provided at spaced apart locations along a beam axis, the detector devices each being configured to generate an electrical signal indicative of passage of a particle through or absorption of a particle by the device; and at least one absorber portion configured to absorb at least a portion of an energy of a particle, wherein one said at least one absorber portion is provided in a particle path between at least one pair of adjacent detector devices, the apparatus being configured to provide an output signal indicative of the energy of a particle, the output signal provided being dependent on the electrical signals indicative of passage of a particle through or absorption of a particle by the devices.
    • 本发明的一些实施例提供了一种装置,该装置具有用于使其辐射的带电粒子通过的粒子束线,该装置包括:第一束跟踪器结构,包括至少一个位置敏感检测器(PSD),用于确定相对于横截面区域 粒子通过PSD的束线的位置; 能量鉴别设备,用于确定已经通过第一波束跟踪器结构的粒子的能量; 以及支撑装置,用于在第一波束跟踪器结构和能量识别装置之间的沿着波束线的粒子路径中支撑物体,所述装置被配置为以第一模式和第二模式中的选定模式运行,所述装置 在第一操作模式中被配置为控制穿过第一射束跟踪器结构的带电粒子束的能量,使得带电粒子吸收的布拉格峰位于对象内,并且在第二操作模式中, 以控制穿过第一射束跟踪器结构的带电粒子束的能量,使得带电粒子吸收的布拉格峰位于能量鉴别装置内。
