Ionising radiation is commonly used as a non destructive probe in medical imaging or other radiography methods to obtain information that isnot available through visual inspection. Detection of ionising radiation plays a major role also in homeland security and other applications as diverse as archeometry and history of art. Finally, detection of ionising radiation plays a key role in the quest for answering a wide range of fundamental physics questions. Some of the most widely used ionising radiation detectors are scintillating crystals, which covert the incoming radiation into visible, scintillation light that can be detected by photosensors coupled to the scintillator.In this project we are interested in improving the sensitivity of scintillator detectors by developing an improved technology for coupling the scintillator surface to the photonsensors. This will provide a relatively economic way to improve a scintillator's performance and has the potential to impact many of the societal applications where these detectors are used but also offer an improved sensitivity for fundamental science research where such scintillators are commonly used.

电离辐射通常用作医学成像或其他放射照相方法中的非破坏性探针，以获得通过目视检查无法获得的信息。电离辐射的探测在国土安全以及考古和艺术史等多种应用中也发挥着重要作用。最后，对电离辐射的探测在回答一系列基础物理问题的探索中起着关键作用。一些最广泛使用的电离辐射探测器是闪烁晶体，它将入射辐射转化为可见的闪烁光，可以通过与闪烁体耦合的光传感器检测到。在这个项目中，我们有兴趣通过开发一种改进的闪烁体表面与光子传感器耦合的技术来提高闪烁体探测器的灵敏度。这将提供一种相对经济的方法来提高闪烁体的性能，并有可能影响许多使用这些探测器的社会应用，但也为基础科学研究提供了更高的灵敏度，这些基础科学研究通常使用这种闪烁体。
