Abstract
The Photon Factory Advanced Ring (PF-AR) at the High Energy Accelerator Research Organization (KEK) was upgraded to improve performance. Vacuum systems were almost thoroughly redesigned and renewed to realize longer beam lifetime, higher stored current, and more reliable operation. Replacement of vacuum components was carried out in 2001. And the commissioning started in January 2002. After one-year operation, the beam lifetime grew 7 times longer than that of the former PF-AR.
