ABSTRACT:
An ion beam accelerating device includes an accelerating cavity including an accelerating cavity outer conductor having a space therein, two accelerating cavity inner conductors though which an ion beam passes and which penetrate respective side walls of the accelerating cavity outer conductor and are separated from each other by a gap in the accelerating cavity outer conductor, and a plurality of magnetic cores disposed in the accelerating cavity outer conductor and surrounding one or both of the accelerating cavity inner conductors. The ion beam accelerating device further includes a plurality of high frequency magnetic field generating units equal in number to the magnetic cores for inducing respective high frequency magnetic fields in respective ones of the magnetic cores, thereby generating an accelerating voltage across the gap so as to accelerate the ion beam passing through the accelerating cavity inner conductors. Alternatively, the magnetic cores may be divided into a plurality of groups of magnetic cores, and the ion beam accelerating device may include a plurality of high frequency magnetic field generating units equal in number to the groups of magnetic cores for inducing respective high frequency magnetic fields in respective ones of the groups of magnetic cores.
