Development of advanced modulators for recirculating heavy-ion accelerators

Several approaches for accelerating heavy-ions have been proposed including RF accelerators, conventional linear induction accelerators, multi-pulse linear accelerators and recirculating induction accelerators (recirculators). A recirculator is an induction accelerator which accelerates the particles and bends them in a closed path with dipole magnetic fields. One of the areas of technology that is critical to the feasibility of a recirculator is the modulator system which generates the pulses that accelerate the ion beams. System studies were conducted which helped identify the desirable modulator characteristics. These system studies are briefly described. (K.A.) 6 refs.; 4 figs
