Two synchrotron light sources are in operation at the High Energy Accelerator Research Organization (KEK): the Photon Factory (PF) storage ring and the Photon Factory Advanced Ring (PF-AR). The 2.5-GeV PF storage ring was largely upgraded during March to September, 2005. Through this upgrade, existing ten straight sections were extended in length, and four short-straight sections were newly created. New short-period undulators were then installed in the new sections. Other developments, including a top-up injection, are in preparation. The other light source, the 6.5-GeV PF-AR, is routinely operated with a single bunch. It provides high-flux hard X-rays for research including time-resolved pulse X-ray experiments. In the PF-AR, four in-vacuum undulators and one elliptically polarized multipole wiggler are in operation. Moreover, a new in-vacuum undulator was installed in summer, 2006. Some operational developments were also carried out. In this presentation, we report both hardware and operational advances of the PF and the PF-AR storage rings.

Installation and assembling of accelerator components for J-PARC 50 GeV Synchrotron are now underway. Off-beam commissioning will be carried out between December 2007 and April 2008, and the full commissioning of J-PARC accelerator complex, which is consisted of an injector linac, a 3 GeV rapid cycling synchrotron and the 50 GeV Synchrotron, will be started from May 2008. This paper describes the status, schedule and method of installation and assembling of accelerator components. Radiation maintenance scenario will be also described.
