Abstract :
A conceptual design of a 100 GeV e+-e- storage ring (LEP) being studied at CERN and some of the problems encountered are presented. The 20 GeV fastcycling injector synchrotron is studied at the Rutherford Laboratory.1 To obtain a luminosity L = 1 ?? 1032 cm-2 s-1 at 100 GeV, the product of bending radius ?? and the RF power PB delivered to both beams must be PB ?? = 136 GWm, assuming optimum coupling, a maximum permissible beam-beam tune shift ??Q = 0.06, and a vertical amplitude function ??y* = 0.01 m at the crossings. The bending radius ?? = 6.1 km was obtained by cost optimisation.2
