Abstract

See full text

A new concept is presented along with different embodiments to produce improved duty cycle of electron beams and multiple beams of different energy from WF, FFAG and other betatron and induction accelerators. These variations are achieved by using the induction core in both directions of induction core swing to accelerate beams in different magnetic guide regions to improve beam repetition rates and duty cycle. The beams may have different energies and intensities. Multiple guide field regions may be used with an induction core while the field is varying in one direction to also produce multiple beams, each differing in energy and intensity. The use of a single core allows improved duty cycle and multiple beams with a substantial increase in performance and reduction of cost in those cases where the induction core, associated power supplies and control are a significant fraction of the cost of such an accelerator.
