PEP-II: an asymmetric B factory based on PEP

An asymmetric B factory to be installed in the PEP (Positron Electron Project) tunnel has been under study for several years. A mature design for a 9 GeV*3.1 GeV electron-positron collider with a design luminosity of 3*10/sup 33/ cm/sup -2/ s/sup -1/ is presented. Solutions exist for all the technical problems, including issues related to high currents (e.g. beam instabilities, feedback systems, vacuum chamber design, lifetime degradation, and radiation power dissipation in the interaction region) and those related to the different energies of the beams (e.g. beam separation, beam-beam interaction, and detector requirements). The status of this project is discussed.<
