High efficiency circuital scheme of hard radiation on base of compact electron accelerators

The new physical schemes of X-ray and /spl gamma/-radiation sources are considered in which the process of photon emission happens at multiple cross by circulating electrons of the thin target. The sources of a bremsstrahlung radiation with additional acceleration of radiating electrons and monochromatic radiation with usage of the crystalline target are discussed. The computer model operation confirms high efficiency of schemes, which allow essentially to increase an yield of both hard and monochromatic photons at maintenance of compact device sizes that is specially important at development of different sources.
