Second generation high gradient quadrupoles for the LHC interaction regions

Conceptual designs of large-aperture high-gradient Nb/sub 3/Sn quadrupoles, suitable for use in a second generation LHC interaction region, are presented. A quadrupole with a 90 mm coil aperture and the same 200 T/m gradient as in the current LHC IR is technically feasible and would allow /spl beta/*=0.25 in to be achieved, doubling the LHC luminosity.
