Abstract
An objective is to provide a circular acceleration apparatus that can accelerate higher currents as well as avoid complex controlling of a deflecting magnetic field generated by an electron deflection unit. The circular acceleration apparatus is provided, which comprising a circular acceleratorincluding an electron acceleration unitand a deflection-magnetic-field generating unit; an electron generator, to which a pulsed voltage is applied, to generate electrons for injecting to the circular accelerator; and a circuit element which generates the pulsed voltage for providing to the electron generatorby making the pulsed voltage applied to the electron generatorhave at least one of a slow rising edge and a slow falling edge.
