Our research group has been studying isotope CT imaging, and is currently working on simultaneous imaging of multiple isotopes. For this purpose, we have devised a method (Flat-LCS) that uses the helical undulator of the storage ring to broaden the energy distribution and reduce the spatial dependence of gamma-ray energy while keeping the beam diameter of a normal laser Compton gamma ray small, and have been conducting experiments at UVSOR. In this study, we measured the isotope abundance ratio of natural lead using the F-LCS beam and the normal LCS, and we report the results.
