Design studies for a large proton-synchrotron and its laboratory

Analysis of the growth pattern of CERN-Meyrin leads to a model for the development of the proposed European 300 GeV Laboratory. The model must allow for flexibility in the development of the machine so that one may exploit future technological advances, e.g. pulsed superconducting magnets. The maximum use must be made of existing capital investment and infrastructure yet provision must also be made for a steady expansion in experimental utilization for 30 years to come. Various types of synchrotron with separated and combined- function lattices and missing-magnet, missing-power and fixed-energy configurations have been designed and costed. Their relative merits are discussed in the context of the model for the new Laboratory.
