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.
