Research and construction of X or gamma radiography array detector for large objects
【摘要】 介绍了大型客体X或γ辐射成像对阵列探测器的技术要求以及国内外现状,超高压阵列电离室的设计、结构、工艺以及主要性能,说明这种阵列探测器在集装箱探测系统中的应用并给出得到的X—辐射投影图像。
【Abstract】 After a brief interpretation of the technical requirements about array detectorsfor large object X or gamma radiography and an introduction of their developmentsituation around the world, this article presents the design, structure, technology andmain characteristics of the super high gas -- pressurized array ion -- chambers. Theapplication of this kind of array detectors in the container inspecting system has beenmentioned. A photograph of the X -- ray scan image is shown at the end of this paper.
