项目摘要

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.

目前，电离辐射作为一种非破坏性的探测器，被广泛应用于医学成像、工业断层扫描、国土安全、考古和艺术史等领域，并在回答许多基础物理问题方面发挥着关键作用。世界各地有许多大型物理实验的例子，例如通过电离辐射测量来探测核结构、粒子物理或天体物理。在这些应用需求和基础研究的推动下，电离辐射探测技术近年来取得了显著进展。然而，在许多情况下，学术界和工业界同时取得了这一进展，它们之间的知识转让有限。在两个社区之间建立牢固的桥梁，促进知识转移，有很大的潜在收益和影响。在这个特定的项目中，我们有兴趣转让位置敏感闪烁体探测器及其在伽马射线成像中的应用技术。这种最先进的技术已经在学术界开发，并已用于基础物理实验。向工业界转让这一技术将使采用伽马射线探测的应用达到更高的灵敏度，特别是将直接影响医学成像和核安全等领域。
