Race-track microtron-recirculator with superconducting RF cavities

The importance of designing and building a modern continuous electron beam accelerator for medium energy and possible directions for the design and implementation of the basic systems of such an accelerator are examined. Substantiation is given for the type of accelerator - a race-track microtorn with energy up to 200 MeV using superconducting accelerating cavities operating at liquid-helium temperature. A novel scheme is proposed for the microtron-recirculator. In this scheme, recirculation with individual deflection and focusing systems is orgnized for the first few orbits; further acceleration occurs in a standard microtron regime.[PUBLICATION ABSTRACT]
