Study on change of transmission cross sections and development of new application field in spectroscopic imaging using a pulsed neutron transmission method

阐明了金属的织构反映的是中子透射截面，并开发了世界上第一个用于导出织构、晶粒尺寸和应变定量信息的分析程序。利用该程序对焊接铁的织构和晶粒尺寸进行了研究，并成功地对原位拉伸试验中铁的织构、晶粒尺寸和应变进行了成像。此外，还研制了一种适用于脉冲中子源的摄像系统。

It has been clarified that texture in metals reflects the neutron transmission cross section and the world's first analysis code for deducing quantitative information of the texture, crystallite size and strain has been developed. By using this code texture and crystallite size of a welded iron were investigated, and also texture, crystallite size and strain of iron during in-situ tensile test were successfully imaged. Furthermore, a camera system applicable to a pulsed neutron source has been developed.
