Abstract
Update of the first-generation undulators installed in 1980s is pushed forward at the PF-Ring taking advantage of the extended straight sections reconstructed in 2005. New undulators have been designed as variable polarizing undulators to obtain various polarization states, not only elliptical polarization but also linear (horizontal and vertical) polarization. Three undulators are to be installed by the end of FY2014 for BL02, BL13 and BL28. At the PF-AR, an independent beam transport line from the injector LINAC is being constructed. The Super KEKB which shares the injector LINAC with the PF-Ring and the PF-AR will be commissioned in FY2015. The full energy top-up injection of the PF-AR will be available as a simultaneous injection with the 7-GeV HER, the 4-GeV LER and the PF-Ring not so later than the commissioning of the Super KEKB.
