The objective is to develop a solid state radiation hard sensor for neutron and gamma detection with long term reliability suitable for use in nuclear power generation plant and other high temperature settings. Use of CVD diamond eliminates the need to use helium-3, a scarce at risk element. Diamond is very radiation hard but is an expensive synthetic material and challenging to process reliably. Past processing issues are understood and solutions available: Areas of innovation include precise laser cutting/plasma processing/patterning (pixellation)/conversion layers for the production of multi-layer devices for neutron detection. Diamond polishing needs to be improved and understood so that optimal, economic devices can be manufactured. Advanced materials science, electron micropscopy, high temperature neutron performance and mechanical stability will be demonstrated to show how this technology can be applied to future power plant designs and radiation monitoring.

目的是研制一种适用于核电站和其他高温环境的、长期可靠的中子和γ探测固体辐射硬传感器。CVD金刚石的使用消除了使用氦-3的需要，氦-3是一种稀缺的危险元素。金刚石是非常抗辐射的，但它是一种昂贵的合成材料，并且难以可靠地加工。了解过去的处理问题并提供解决方案：创新领域包括精确的激光切割/等离子体处理/图案化（像素化）/转换层，用于生产用于中子检测的多层设备。金刚石抛光需要改进和理解，以便可以制造最佳的，经济的设备。先进的材料科学、电子显微镜、高温中子性能和机械稳定性将被展示，以展示这项技术如何应用于未来的发电厂设计和辐射监测。
