[1M12] Demonstration of Isotope CT Using NRF Absorption Method in UVSOR-BL1U
Keywords:Nuclear resonance fluorescence (NRF), Computed Tomography (CT), Laser Compton Gamma-ray Beam, Isotope Distribution
By combining the Computed Tomography (CT) technique and Nuclear Resonance Fluorescence (NRF) absorption method (NRF-CT), an isotope specific CT image could be obtained. We have already obtained an isotope-specific CT image of 208Pb in the CT target consisted of a natural lead rod, an iron rod, and vacancy in an aluminum cylinder shielded by an iron cylinder in the BL1U of UVSOR facility. To obtain a higher resolution image and to examine the capability of isotope identification, the CT target was changed to three lead rods with a natural lead, an enriched 208Pb, and an enriched 206Pb put into a bismuth cylinder. The NRF-CT image of 208Pb obtained by the experiment will be discussed.
