The Institute of Particle Physics is preparing a proposal to design and build a 10 GeV electron–positron ring to study electron–proton collisions at the Fermi National Accelerator Laboratory using the 1000 GeV protons from the Tevatron. The design and operation of a high-power electron linear accelerator is very similar to the accelerating system in an electron–positron storage ring. This report describes the design of an rf system for the main ring which has many characteristics similar to that found in the Electron Test Accelerator at Chalk River. Discussion of quantum lifetime, the amplitude of synchrotron oscillations, and the consequent choice of the size of the beam aperture have led to the design of a new structure which operates at a higher frequency than that used in the large storage rings presently in operation.
