Heavy-ion accelerators are considered to be one of the promising driver alternatives for inertial fusion. In a heavy-ion inertial-fusion driver, multiple beams of heavy ions are accelerated to the kinetic energies needed to ignite a fusion target. During acceleration, the beams of heavy ions are compressed from initial pulse durations of 10`s to 100`s of microseconds to a final pulse duration in the reactor of approximately 10 nanoseconds. The compressed beam of heavy ions is focused on the target in a reactor chamber where the energy released from the fusion reaction is converted to thermal energy and eventually to electricity. Several approaches for accelerating heavy-ions have been proposed including RF accelerators, conventional linear induction accelerators, multi-phase linear accelerators and recirculating induction accelerators. A recirculator is an induction accelerator which accelerates the particles and bends them in a closed path with dipole magnetic fields. A single beam traverses the same accelerating cavities many times to acquire its final energy. The primary motivation to evaluate recirculators is the potential for significant cost reduction over conventional linear induction accelerators. The idea of recirculation is not new, but only recently has a thorough investigation of this concept been conducted.
