New Photo Detection Technology for Possible Use in Sensors for Homeland Security

本计画将探讨将新兴的矽光电倍增器应用于一系列新的小型闪烁计数器系统的可能性。这些新型探测器将被设计成独立的，配有精密偏置电源和前端电子设备。这些强大的新探测器有可能在国土安全和边境保护情况下找到应用。随后，这些信息可能会越来越多地提供给第一反应小组，供其在紧急情况下使用。在这一研究方案期间，我们还将探索一种新的紧凑型定向伽马射线光谱仪的潜力，这种光谱仪将能够引导用户朝向辐射源，同时提供对该辐射源性质的识别。还将探索一种新的紧凑型中子传感器，以探测货物中隐藏的裂变材料。

This project will explore the posibility of applying newly emerging silicon photo-multiplier devices in a new range of very compact scintillation counter systems. These novel detectors will be designed to be self-contained, complete with their precision bias supply, and front-end electronics. These powerful new detectors have the potential to find application in Homeland Security and Border Protection situations. They may then later become increasingly available to First-Responder Teams for use in emergency situations. During this programme of research, we will also explore the potential for a new compact directional gamma-ray spectrometer that will be able to guide the user towards the source of radiation whilst simultaneously providing an identification of the nature of that source. A new, compact neutron sensor will also be explored to detect hidden fissile material in cargo.
