Abstract

The GeV photon beam at SPring-8 is produced by backward-Compton scattering of laser photons from 8 GeV electrons. Polarization of the photon beam reaches to 100 % at the maximum energy if laser photons are 100 % circular polarized. The photon energy will be above 3 GeV thanks to the high energy of the circulating electron beam. The photon energy is measured by tagging the recoiled electron. The photon beam well defined in both the polarization and energy becomes a clean and sharp probe to study the baryon and meson structures in terms of quarks and their dynamics. We present the outline of the project. A few selected topics studied in the SPring-8 Laser-Electron Photon Collaboration are also discussed.
