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.

周长560米的第三代同步加速器光源被称为钻石，目前正在牛津郡的奇尔顿/哈威尔科学园区建设。该设备将为生物和化学材料的X射线衍射、光谱学和显微镜研究提供英国无与伦比的设施，该设施最终将拥有约30个材料研究实验站。现有的探测器技术不足以覆盖广泛的应用。这项拨款申请主要集中在粉末衍射站的仪器上。该空间站的技术开发是钻石探测器组的最高优先级，尽管我们注意到与这里正在研究的技术相关的技术也将在许多其他光束线上具有潜在的应用。格拉斯哥组已经开始开发一种新型的3D探测器技术，该技术在半导体（这里是硅）晶片上制造数千个孔。该技术在同步加速器和其他应用中具有优于传统平面技术的显著优势：3D设备是无边缘的（它们在距离切割边缘10微米处是有效的）; 3D像素是自屏蔽的，防止电荷共享并提高能量分辨率能力;设备在大动态范围内具有线性响应;快速脉冲的发展使设备本质上具有抗辐射性。该项目的目的是设计和制造一个可行的原型传感器集成现有的读出电子。在这个为期三年的项目结束时，一个原型设计将在钻石进行测试，该技术将足够成熟，以转移到该项目的建设阶段的工业。
