The PF-AR is a full-time single-bunch light source for SR experiments in the X-ray region. Electrons are injected at 3.0 GeV and ramped up to the final energy of 6.5 GeV for normal user operation or 5.0 GeV for medical application. The typical initial beam current is 55 mA at 6.5 GeV and the beam lifetime is 15 h at 50 mA. The initial single-bunch impurity better than 10-8 was achieved, however, degradation of the impurity during the users' run has to be solved. Since the present emittance of 290nm{center_dot}rad is not satisfactory, we are making an effort to realize the minimum attainable emittance of 160nm{center_dot}rad. The high quality of pulse X-ray has brought us abundant occasions to do time-domain and/or time-resolved measurements.
