The aim of this project is to use of a recently developed neutron detector, with a data processing electronic system to develop a neutron imager for precise location of neutron-emitting materials in decommissioning facilities. In this project student will use a coded-aperture (mask with array of apertures), where materials (113Cd, W, W-113Cd, W-HDPE), as well as various thicknesses will be considered. Radiation intensity pattern would be projected on the front face of the detector and interactions would be detected by a position-sensitive photomultiplier. The detector output would be connected to the data processing electronic and, is required to programme in order to digitise & stream the intensity pattern to a personal computer. By decoding the digitised pattern using appropriate techniques & programming skills, a neutron image would be able to generate in real-time corresponding to the area investigated. The complete unit would be portable and, expected to be fully automated.

该项目的目的是利用最近开发的中子探测器，配合数据处理电子系统，开发中子成像仪，用于对退役设施中的中子发射材料进行精确定位。在这个项目中，学生将使用编码孔径（孔径阵列掩模），其中材料（113 Cd，W，W-113 Cd，W-HDPE），以及各种厚度将被考虑。辐射强度模式将投射在探测器的正面，相互作用将由位置敏感的光电倍增管探测。探测器输出将连接到数据处理电子设备，并且需要编程以将强度图案数字化并流式传输到个人计算机。通过使用适当的技术和编程技能对数字化图案进行解码，将能够实时生成与所研究区域相对应的中子图像。整个装置将是便携式的，预计将完全自动化。
