We design a high-intensity Compton-backscattered photon beam facility at the PLS. A laser beam is shot to head-on collide with 2.5 GeV electrons, so that it produces a highly polarized photon beam with the wide energy range spanning between a few MeV and 400 MeV. We study the maximum photon beam intensity and the polarization of Compton backscattered photon beams with three different wavelength lasers (CO2, Nd-YAG, and Ar-ion). We present design parameters for the proposed Compton beam facility as well as experimental programs. Simulation results on the increase of energy spread due to Compton backscattering in the PLS storage ring are also presented.
