Outline of Final Research Achievements

To establish an isotope imaging method by using LCS gamma-ray and Nuclear Resonance Fluorescence, the LCS beamline which can generate LCS gamma-rays whose maximum energy is 5.4 MeV and maximum flux of 10^7 gamma/s has been developed in UVSOR-III.
The CT sample consisted of lead rod, iron rod, air void embed into aluminium body with iron outer ring was tested at the LCS beamline in UVSOR-III. The transmission NRF measurement has been performed to measure the NRF absorption in the CT sample in 7 points in horizontal axis in 5 mm step and 5 rotation angles. The CT reconstruction result clearly proofed that 208Pb distribution in the CT sample can be obtained by our proposed method of the isotope imaging.
