Abstract

The SuperKEKB is now in a construction stage. The injector linac should be upgraded for realizing the 40times higher luminosity than that of KEKB. This requires both bunch charge increase and reduction of beam emittance. All of the relevant hardware designs for the injector system are being finalized now to meet the commissioning of the ring by the end of 2014. In the present paper is briefly reviewed the overall progress of such design decisions and hardware developments in the last two years. A perspective towards the commissioning is also presented.
