Abstract

The magnet lattices of a chain of two proton synchrotron and three dc storage rings for the proposed TRIUMF KAON Factory are described. The KAON Factory will provide pulsed and dc proton beams of 30 GeV and 100 PA and will be fed from the existing TRIUMF cyclotron. The rapid cycling Booster (50 Hz) accelerates from 440 MeV to 3 GeV; the 10 Hz main ring is 5 times larger and brings the energy to 30 GeV. The lattices are all of the separated-function type. For avoiding serious beam losses at transition the transition energy is driven far above the top energy of the accelerators. This feature is obtained mainly by creating a superperiodic structure with missing magnet cells and by choosing the horizontal tune just below the number of superperiods. A special arrangement of the rf accelerating cavities is used to avoid synchro-betatron coupling. Fast extraction systems are described.
