Induction synchrotron with a constant magnetic field

Abstract

In this paper the possibility of accelerating charged particles in a “nearly constant” orbit in a timeconstant magnetic field is discussed. The closed trajectories of the accelerated particles are formed by azimuthally set short bending magnet sections, each comprised of two particle-deflecting magnetic dipoles in which the incidence and deflection angles do not depend on the particle energy. The sign-alternating focusing of the beam is carried out by the dipole fields and quadrupole lenses placed between the bending sections. The particles are accelerated by pulses of the electric field of the induction sections. The inductive pulses and the beam pulses are synchronized by a beam-transit time transducer. The stability of the longitudinal oscillations is determined by the shape of the top of the accelerating pulse. The nonresonance acceleration method does not require preaccelerators and boosters.
