A new thermal neutron irradiation facility, devoted to carry out both dosimetric and radiobiological studies on boron carriers, which are being developed in the framework of INFN BNCT project, has been installed at the ENEA Casaccia TAPIRO research fast reactor. The thermal column, based on an original, hybrid, neutron spectrum shifter configuration, has been recently become operative. In spite of its low power (5 kW), the new facility is able to provide a high thermal neutron flux level, uniformly distributed inside the irradiation cavity, with a quite low gamma background. The main features and preliminary benchmark measurements of the Beam-shaping assembly are here presented and discussed.
一个新的热中子辐照设施已安装在意大利国家新技术、能源和可持续经济发展局（ENEA）卡萨西亚TAPIRO研究快堆上，该设施致力于对硼载体进行剂量学和放射生物学研究，这些研究是在意大利国家核物理研究所（INFN）硼中子俘获治疗（BNCT）项目框架内开展的。基于一种原始的混合中子谱移位器配置的热柱最近已投入使用。尽管该新设施功率较低（5千瓦），但它能够在辐照腔内提供均匀分布且伽马本底相当低的高热中子通量水平。本文介绍并讨论了束流整形组件的主要特性和初步基准测量结果。
