Abstract
The accelerator includes a source of an ensemble or bunch of ions and a plurality of relatavistic electron beam stages, each of which generate a high current electron beam which in turn are injected along the accelerator centerline in a timed sequence to accelerate the ion bunch to increasingly high kinetic energy levels. In each relatavistic electron beam stage, a region of high electric charge is created by the discharge of a high current, short duration pulse between a cathode and anode. The electron beam created by the discharge stops a short distance beyond the anode, due to the buildup of its electric charge, thereby creating a region of high charge which accelerates the ion bunch. Each successive relatavistic electron beam stage is timed to fire when the ion bunch arrives at the region of high charge of that stage, and in operation, increases the kinetic energy of the ion bunch by a factor equal to or greater than the kinetic energy of the electron beam.
