Abstract :
A discussion is presented of the magnet lattice design of a high luminosity 51 0-MeV electron-positron collider, based on high-field superconduction bending dipoles. The design criteria are flexibility in the choice of the tune and beta functions at the interaction point, a horizontal emittance larger than 1 mm-mrad to produce a luminosity larger than 10/sup 32/ cm/sup -2/s/sup -1/, a large synchrotron radiation damping rate, and large momentum compaction. The RF system parameters are chosen to provide a short bunch length also when the beam energy spread is determined by the microwave instability. A satisfactory ring dynamic aperture and a simultaneous small value of the horizontal and vertical beta functions at the interaction point should be achieved using Cornacchia-Halbach modified sextupoles.<>
