The Photon Factory Advanced Ring (PF-AR) is a 6.5-GeV synchrotron light source at the High Energy Accelerator Research Organization (KEK). It can provide high-flux hard X-rays for such research as the materials science, structural biology and medical applications. The PF-AR has five insertion devices including four in-vacuum undulators. It is operated with a single bunch which fits for time-resolved experiments. A special 5-GeV operation is partly provided for a clinical application. An initial beam current and a beam lifetime are 60 mA and approximately 14 hours, respectively. Recent developments include an installation of a new in-vacuum undulator (U no. NW14-36) to the west rf section, which was accompanied by transferring two rf cavities to other section. The undulator has been successfully operated at a minimum magnetic gap of 10 mm. We also carried out such accelerator studies as a successful test of beam injection using a pulsed quadrupole magnet, a study of low emittance optics, an establishment of two-bunch operation for the clinical application, a successful operation of a multi-bunch feedback system, and an installation of a test undulator which enables us to control polarization using a new arrangement of magnets.
