Evaluation of the properties for quasi-monoenergetic neutron calibration fields of high energies more than 20 MeV at TIARA is proceeding for development of the field. Among the properties needed for the development as the standard calibration field, we report on measurement of the neutron beam profile using an imaging plate with a polyethylene converter and on estimation of the contribution of scattered neutrons into the irradiation field based on pulse height distribution at various off-beam positions measured using an organic liquid scintillation detector.
为了开发该场，日本原子能研究开发机构正在对能量超过20 MeV的高能准单能中子校准场的特性进行评估。作为标准校准场开发所需的特性之一，我们报告了使用带有聚乙烯转换器的成像板测量中子束轮廓，以及基于使用有机液体闪烁探测器在不同离束位置测量的脉冲高度分布估计散射中子对辐照场的贡献。
