Outline of Final Research Achievements

Backward Compton scattering (BCS) of X-ray photons emitted from undulator in the electron storage ring and reflected back by a single crystal can produce a quasi-monochromatic gamma-ray beam up to an energy very close to the stored electron beam energy. The SPring-8 beam diagnostics beamline (BL05SS) is used to inject a reflected undulator X-ray radiation against 8 GeV stored electron beam and to extract a quasi-monochromatic 8 GeV gamma-ray produced by BCS. BL05SS has conditions to do a pilot experiment to obtain the gamma-ray beam. Reflectivity measurement of silicon and diamond Bragg mirrors at normal-incidence (90 degree) had been done. We confirmed that the reflectivity of diamond C(444) is 94%. Experimental setup including a Bragg mirror system was constructed. Also, we developed a new detector for high-energy gamma-ray which is comprised of eight PWO scintillators. We have tried to produce an 8GeV quasi-monochromatic gamma-ray beam using our newly developed system.
