KEK fast cycling booster
The KEK GeV Proton Synchrotron aims at an intensity as high as 10/sup 13/ protons/pulse. For instance, a combination of a 50 MeV linac and 8 to 10 GeV separated function type synchrotron with reasonable aperture planned in the early stage of designing gives the space charge limit of 1.8 x 10/sup 12/ protons/pulse. By inserting a 500 MeV booster synchrotron and replacing with a 20 MeV linac, the incoherent space charge limit of the main synchrotron is raised to 2.0 x 10/sup 13/ protons/pulse. The 500 MeV booster is a fast-cycling combined-function type AG synchrotron with a repetition rate of 20 Hz. The mean radius of the booster is 6 m, which corresponds to one ninth of the main ring. Nine beam pulses from the booster every two seconds are stacked into the main ring longitudinally. Synchronization between the rf accelerating systems of the booster and the main ring requires the transition energy of the booster as far as possible from the ejection energy of the booster. Several candidates for the lattice structure of the booster synchrotron were studied, and triplet lattice of FDFO was chosen from the view point of the high transition energy.
