The present operational status of the Photon Factory storage ring (PF-ring) and the Photon Factory advanced ring (PF-AR) in KEK is reported. The scheduled user times of them were more than 4000 hours in FY2006. In the last summer shutdown, new undulators were installed in both of the rings and have been stably operated. A top-up operation in a single-bunch mode was demonstrated for six days in February...
We successfully reduced the emittance of the Photon Factory storage ring (PF ring) to as low as 28 nm-rad, which is very close to the theoretical minimum (27.3 nm-rad) under the present lattice configuration. The new low emittance optics had been already tried, however, we could not examine it sufficiently because of a poor injection rate. Recently, new kicker magnets developed for the new optics...
