Dynamic aperture and extraction studies for the SSC High Energy Booster

Results of a study made to evaluate the coil-winding aperture needed for the final booster in the injector chain for the SSC (Superconducting Super Collider) are presented. Lattice designs based on 5-cm and 7-cm dipole apertures are evaluated by looking at the long-term dynamic aperture, at injection and the good-field aperture requirement for resonant extraction of high-energy test beams. The 5-cm dipole is found to be marginal, while the 7-cm dipole satisfies field quality criteria for both injection and extraction.<
