The 560m circumference third generation synchrotron light source known as Diamond is currently under construction on the Chilton/Harwell science campus in Oxfordshire. This device will provide an unparalleled facility in the UK for the X-ray diffraction, spectroscopy and microscopy investigation of biological and chemical materials.The facility will eventually have approximately 30 experimental stations for material investigation. Existing detector technologies are insufficient to cover the wide range of applications. This grant application primarily focuses on an instrument for the powder diffraction station. The development of technology for this station is the highest priority for the Diamond detector group, although we note that technologies related to those under study here will also have potential applications on a number of other beam-lines.The Glasgow group has already started development of a novel 3D Detector technology in which thousands of holes are made through a semiconductor (here silicon) wafer. This technology has significant advantages over conventional planar technologies for synchrotron and other applications: the 3D devices are edgeless (they are active to 10 microns from the cut edge); the 3D pixels are self-shielding preventing charge sharing and improving energy resolution capabilities; the devices have a linear response over a large dynamic range; the fast pulse developments make the device intrinsically radiation hard. The aim of this project is to design and fabricate a viable prototype sensor integrating existing readout electronics. At the end of this three year project a prototype devise will be tested at Diamond and the technology will be sufficiently mature to transfer to industry for the build phase of this project.

目前，牛津郡的Chilton/Harwell Science Campus正在建造560m圆周的第三代同步器光源。该设备将在英国提供无与伦比的设施，用于对生物和化学材料的X射线衍射，光谱和显微镜研究。该设施最终将有大约30个实验站进行材料研究。现有的探测器技术不足以涵盖广泛的应用。该赠款应用主要集中在粉末衍射站的仪器上。该电台的技术的开发是钻石探测器组的最高优先级，尽管我们注意到，与此处研究的技术相关的技术也将在许多其他梁线上具有潜在的应用。GlasgowGroup已经开始开发一种新型的3D检测器技术，其中成千上万的孔是通过半导体（这里的Silicon）Wafer制成的。这项技术比传统的平面技术具有显着优势，用于同步器和其他应用：3D设备是无端的（它们从切割边缘处活跃至10微米）； 3D像素是自挡的，以防止电荷共享和提高能源分辨率的能力；设备在大型动态范围内具有线性响应。快速的脉冲开发使设备本质上的辐射艰难。该项目的目的是设计和制造一个可行的原型传感器，集成了现有的读取电子产品。在这个三年项目结束时，将在钻石上测试原型的原型，该技术将足够成熟到该项目的构建阶段转移到行业。
