Abstract :
To achieve the enormous luminosity required for B factories it is necessary to increase the factor I xi /sub V// beta */sub V/. The possibility of decreasing beta */sub V/ by using locally shortened bunches is investigated. The lattice and optics were designed to accommodate the CESR (Cornell Electron Storage Ring) tunnel. The beam-beam interaction was simulated for the following conditions: finite bunch length, longitudinal beam-beam kicks, and crossing angle collision geometry. Estimations and simulations show that by using a method of local bunch shortening, it is possible to design the ´after 10/sup 34/´ generation of e/sup +/e/sup -/ colliders with luminosities approximately 10/sup 35/.<>
