DAFNE2: Lattice for a 2 GeV Electron Collider
  Within the general frame of the upgrade of the collider DAFNE to the neutron-antineutron energy threshold (2-2.5 GeV c.m.), modifications and different options for the accelerator design are discussed and a possible lattice for the Main Rings at 1 GeV is presented. The luminosity required by the experiments for such a light quark factory is of the order of few 10^31 cm-2 s-1, easily achievable in the particle factory era.
