The facility is composed of a 230 MeV synchrotron, a 7 MeV H⁻ linac injector and two experimental stations. It can provide a flux of 10⁵~10⁸ p/cm²/s with the uniformity of better than 90% on the 10 cm×10 cm sample. The overall design of XiPAF accelerator is presented in this paper. And the progress of project is reported also.
