High-power ultraviolet and x-ray sources

The review is devoted to the problem of using cyclic electron accelerators and storage rings as sources of high-power ultraviolet radiation and x rays. A brief description is given of the properties of synchrotron radiation and also of the undulatory radiation which can be generated in such installations. Particular cases of use of these radiations are discussed. The parameters of Soviet accelerators and storage rings and the intensities of the synchrotron radiation beams from these installations in the far ultraviolet and x-ray regions of the spectrum are given. These characteristics are compared with the corresponding data for the DESY synchrotron at Hamburg, whose radiation is extensively used for x-ray structural analysis of biological polymers, investigation of the electronic structure of solids and gases, surface phenomena, and many other purposes.
