| 摘 要： | 探测器是辐射成像系统中的关键器件之一,探测器的性能优劣和成像系统的最终指标关系密切,因此在做成像系统设计时关于探测器的物理计算足非常关键的内容.本文利用MCNP模拟了3种闪烁体材料的性能指标(粒子探测效率,能量沉积率,有效沉积因子)是设计高能辐射成像系统的基础工作之一,具有借鉴意义.

| Abstract: | The detector is one of the important devicese of the imaging system,the relationship between the detector's performance and the imaging system's indices is tightness. So the calculation of the detector materials's performance is an importan work in imaging system design. This paper simulats the performances(detection efficiency,energy deposition,effective deposition factor) of three kinds of detector materials,which is a basic work to design the high quality imaging system. |
