Study of Silicon+6LiF thermal neutron detectors: GEANT4 simulations versus real data
摘要:
替代性热中子探测技术和方法的研究和开发是当前需要的。商业固态硅探测器,加上含有6Li的中子转换器层,已被证明代表了一个可行的解决方案,如文献中存在的几个应用。为了更好地了解这些探测器的详细操作以及响应和效率,进行了一系列专门的GEANT 4模拟,并与在几种不同配置中收集的实际数据进行了比较。结果表明,数据和模拟之间的显着一致性,表明探测器的行为是完全理解的。
英文摘要:
Research and development on alternative thermal neutron detection technologies and methods are nowadays needed as a possible replacement of 3He-based ones. Commercial solid state silicon detectors, coupled with neutron converter layers containing 6Li, have been proved to represent a viable solution for several applications as present in literature. In order to better understand the detailed operation and the response and efficiency of such detectors, a series of dedicated GEANT4 simulations were performed and compared with real data collected in a few different configurations. The results show a remarkable agreement between data and simulations, indicating that the behavior of the detector is fully understood.
