Flat-Laser Compton Scattering Gamma-ray beam (F-LCS), which has a flat distribution in the energy spectrum and the spatial distribution with a small beam size, has been developed to study an isotope selective CT Imaging application in the beamline BL1U in UVSOR. We pro-pose generation of an F-LCS beam by using a circular motioned electron beam, which can be generated by a helical undulator installed in a storage ring, and collision with an intense laser beam. A simulation study on the LCS beamline BL1U in UVSOR shows a weak magnetic field (K=0.2) can generate an F-LCS beam. A demonstra-tion experiment has been carried out in UVSOR with the APPLE-II undulator. The spectra of the LCS beams were measured by using a 120% Ge detector. As a result, the energy bandwidth of the LCS peak was observed. The energy bandwidth measured in the energy spectra and the distribution map agreed with the EGS5 simulation.
