【 摘 要 】

Usually there is a large longitudinal emittance growth during transition crossing in Booster. The combination of both the rf manipulation and the {gamma}{sub T} jump can reduce the longitudinal emittance growth during transition to a negligible level. So the goal for Booster to be able to deliver 8-GeV proton beams to Main Injector at the intensity of 4.5 x 10{sup 12} per batch with {var_epsilon}{sub L} of 0.12 eV {center_dot} sec and {Delta}p of 18 MeV can be achieved.
