Low emittance lattice and final focus design for a SuperB project

Very low emittances and small beta functions at the interaction point(IP) are needed to achieve the design luminosity of 10³⁶ cm^-2 s^-1 for a SuperB project. Two rings of 4 and 7 GeV have been designed with the same emittances and damping times. A new Final Focus section has also been designed to strongly squeeze the colliding beams both in the horizontal and the vertical plane at IP, while providing local correction of the large chromaticity and exploiting the large crossing angle and crab waist concepts. Lattice features and chromaticity correction schemes will be discussed here. Dynamic apertures, with damping wigglers similar to those of ILC, will also be presented.
