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

阐明了金属中织构反映了中子透射截面，并开发了世界上第一个推导织构、晶粒尺寸和应变定量信息的分析程序。利用该程序研究了焊接铸铁的织构和晶粒尺寸，并成功地成像了原位拉伸过程中的织构、晶粒尺寸和应变。此外，一个适用于脉冲中子源的相机系统已经开发出来。

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.
