针对校准实验室内强γ射线辐射场束流应用及特性诊断需要，本文建立了辐射场束流特性模拟方法，设计了大面积快响应闪烁体与高速CCD相机组成的束流诊断系统。通过理论模拟及实验测量，在亚毫米位置分辨指标下，实现了对该辐射场内不同距离的束流均匀性、发散角、束流中轴线及快门渡越时间测量。

In order to meet the requirement of application and diagnosis of beam for intensiveγ‐ray radiation field in the calibration laboratory ,a radiation field beam simu‐lation model was established and a large area and fast response imaging system was developed ,which was composed of high‐speed CCD camera and scintillation detector . Through simulation and experiment ,the beam parameters were gained under measure‐ment millimeter spatial resolution for the radiation field ,including uniformity ,diver‐gence angle ,the axis of the beam and shutter transit time .
