| Injector linac at KEK is now under the way to produce high current and low emittance beams for SuperKEKB. The target luminosity for SuperKEKB is 40 times higher than that of KEKB. A short-range transverse wakefield and a dispersive effect at the linac cause an emittance growth, and a longitudinal wakefield effect enlarges an energy spread of the beams. In this presentation, we will show simulation studies concerning the emittance preservation and the energy spread issues. |
