Novel non-destructive quantification technique for the sub-percent carbon in steel by accelerator muons

(English translation 2024-05-16)

The research group in which Dr.Go Yoshida (Assistant Professor of Radiation Science Center) participates as a co-experimenter has developed a non-destructive method for quantifying carbon that is contained in steel below one percent, by using muon beams in J-PARC. The new technique of the muon lifetime measurement method contributed significantly to this achievement. The research is expected to be applied to quality control of steel and analysis of archeological samples made of steel such as Japanese swords. This achievement will also lead to the development of a new analysis method for light elements other than carbon.
