An accelerator-driven thermal neutron source for BNCT, planned to be installed at the INFN Laboratori Nazionali di Legnaro (LNL), is in progress in the framework of the SPES (selective production of exotic species) research program. The most critical element of such a facility is the construction of a reliable neutron converter based on the (9)Be(p,xn) nuclear reaction, working at a high power level (150 kW) and 5 MeV beam energy, due to the SPES driver constraints. Two original, beryllium-based, target concepts have been designed for such a purpose. The present status of the neutron converter, as well as the test results performed so far on prototypes constructed, is reported here.
一个计划安装在意大利国家核物理研究所莱尼亚罗国家实验室（LNL）的用于硼中子俘获治疗（BNCT）的加速器驱动热中子源，正在选择性产生奇异核素（SPES）研究项目的框架内建设中。由于SPES驱动装置的限制，这种设施最关键的部分是基于（9）Be（p，xn）核反应构建一个可靠的中子转换器，该转换器要在高功率水平（150千瓦）和5兆电子伏束流能量下工作。为此设计了两种基于铍的原始靶概念。本文报道了中子转换器的现状以及到目前为止在已构建的原型上进行的测试结果。
