Abstract

This paper describes a few outstanding features of the beam-optical lattice of the KEKB colliding rings. A chromaticity correction scheme with non-interleaved sextupole pairs, a new cell structure with 2.5π betatron phase advances, etc. have been introduced. The lattice successfully squeezed the vertical beta functions at the interaction point, which greatly contributed to the achievement of the world’s highest luminosity.
