Position reconstruction of gamma-ray interaction in scintillator crystals

如今，许多应用都采用电离辐射作为一种非破坏性探针，以获得通过目测无法获得的信息。这些应用范围从医学成像到工业断层扫描和国土安全，以及考古和艺术史。此外，电离辐射在寻求回答广泛的基本物理问题方面起着关键作用。世界上有许多大规模物理实验的例子，例如，通过电离辐射测量核结构、粒子物理或天体物理。在这些苛刻的应用和基础研究的推动下，检测电离辐射的技术近年来取得了显著的进步。然而，在许多情况下，这种进展是在学术界和工业界同时发生的，它们之间的知识转移受到限制。在两个社区之间建立牢固的桥梁将促进知识转移，这将产生巨大的潜在收益和影响。在这个特别的项目中，我们有兴趣转让位置敏感闪烁体探测器的技术及其在伽马射线成像中的应用。这种最先进的技术已经在学术界开发出来，并且已经在基础物理实验中使用。将这项技术转让给工业将使采用伽马射线探测的应用达到更高的灵敏度，特别是它将直接影响医疗成像和核安全等领域。

Nowadays numerous applications are employing ionising radiation as a non destructive probe to obtain information that is not available through visual inspection.These applications range from medical imaging to industrial tomography and homeland security as well as archeometry and history of art. Furthermore, ionising radiation plays a key role in the quest for answering a wide range of fundamental physics questions. There are numerous examples of large-scale physics experiments around world to probe, for example, nuclear structure, particle physics or astrophysics through measurements with ionising radiation. Driven by these demanding applications and fundamental research, the technology for detecting ionising radiation has seen a remarkable progress in recent years. This progress, however, has occurred in many cases in academia and industry in parallel and the transfer of knowledge between them has been limited. There is a great potential gain and impact in building strong bridges between the two communities that will facilitate the knowledge transfer.In this particular project we are interested in transferring the technology on position sensitive scintillator detectors and their use in gamma-ray imaging. This state-of-the-art technology has been developed within the academic community and is already being used in fundamental physics experiments. The transfer of this technology to industry will enable applications employing gamma-ray detection to reach a higher level of sensitivity and in particular it will impact directly areas such as medical imaging and nuclear security.
