As the commissioning phase of the Nagoya University Accelerator-driven Neutron Source for boron neutron capture therapy, in-phantom thermal neutron flux measurements were conducted using a small ⁶LiF/Eu:CaF₂ scintillator detector and activation foils. The spatial distribution of the measured thermal neutron flux agreed with the Monte Carlo simulation results. Based on this comparison, the free-in-air neutron spectrum, calculated at the exit aperture, was verified and the epithermal neutron flux, at a 0.25 mA proton current, was evaluated as (1.49 ± 0.10) × 10⁷ n/(cm s).
随着名古屋大学用于硼中子俘获治疗的加速器驱动中子源的调试阶段的进行，使用小型 ⁶LiF/Eu:CaF₂闪烁探测器和活性箔进行了体模内热中子通量测量。测量的热中子通量的空间分布与蒙特卡罗模拟结果一致。基于此比较，验证了在出口孔径处计算的自由空气中中子能谱，并评估了在 0.25 mA 质子电流下的超热中子通量为 (1.49 ± 0.10) × 10⁷ n/(cm s)。
