Digital Single Photon Sensors to Enable a Step change in Civil Radiation Detection

人们越来越担心放射性装置爆炸的风险，比如在西方主要城市发生的“脏弹”。克罗梅克公司向美国政府提供手持式辐射探测器，作为其建立发现此类威胁能力计划的一部分。为了开发其设备以满足该应用的新要求，Kromek将与爱丁堡大学合作开发和评估他们最近出现的单光子雪崩二极管（SPAD）设备，以实现手持探测器的尺寸，重量，功率和性能的阶跃变化。该项目将根据应用需求评估SPAD的当前实施方案，允许重新设计和制造新芯片，该芯片将全面表征辐射探测。

There is a growing concern over the risk of detonation of a radiological device, such as a "dirty bomb" in a major western city. Kromek supplies handheld radiation detectors to the US Government as part of their programme to build a capability to find such threats. In order to develop its devices to meet emerging requirements for this application, Kromek will work with the University of Edinburgh to develop and assess their recently emerged single-photon avalanche diode (SPAD) devices to enable a step change in size, weight power and performance of the handheld detectors. This project will assess a current embodiment of a SPAD against the application requirements, allowing a redesign and fabrication of the new chip, which will be comprehensively characterised for radiation detection.
