an injector for injecting electrons from the electron generator;
an accelerator for accelerating the injected electrons;
a deflection electromagnet for generating a deflection magnetic field to deflect the injected electrons and accelerated electrons; and
a target with which the accelerated electrons are made to collide, whereby electromagnetic waves are generated, wherein deflection electromagnet has a shape focusing injected electrons or accelerated electrons, the circular accelerator has stable electron closed orbits that, through the deflection electromagnet focusing of the circular accelerator, are situated in a region with a predetermined width in a radial direction, the electron closed orbits been stable during step and an acceleration step, the target is arranged across the stable electron closed orbits and, in accordance with the arrangement of the target, so that a collision region, where a circulating electron beam collides with the targets and at least one non-collision region that is adjacent to the collision region and in which a circulating electron beam does not collide with the targets are located, within the stable electron closed orbits, and through control of respective patterns of changes with time in a deflection magnetic field created by the deflection electromagnet and in electron-beam acceleration, a given electron closed orbit is shifted between the collision and the non-collision regions, whereby the target and a circulating electron beam collide with each other, thereby generating electromagnetic waves.

Abstract
A compact and low-cost electromagnetic wave generator in which X-rays having high intensity can be generated and the energy of generated X-rays can rapidly be switched. In an electromagnetic wave generator including a circular accelerator, a deflection electromagnet incorporated in the circular accelerator focuses injected and accelerated electrons, The circular accelerator produces stable electron closed orbits in a region with a predetermined width in the radial direction of the accelerator that are stable during injection and acceleration of electron. A target is arranged across the stable electron closed orbits and a collision region, where a circulating electron beam collides with the target and a non-collision region where a circulating electron beam does not collide with the target produced. Through control of respective patterns of changes with time in the deflection magnetic field, a given electron closed orbit is shifted between the collision and the non-collision regions, thereby generating X-rays.
