Abstract

Undulators in electron/positron accelerators are powerful sources of UV radiation and X-rays. The field-generating elements in classical undulators are either permanent magnets or electromagnets. For undulators with short periods, permanent magnets are used and the field strength (for a given period length and gap) is limited by the material properties. In this paper a novel concept is described which allows these limitations to be overcome by using an in-vacuo undulator with superconductive wires.
