Cyclotrons and FFAG Accelerators as Drivers for ADS

Abstract

This review summarizes projects and studies on circular accelerators proposed for driving subcritical reactors. The early isochronous cyclotron cascades, proposed about 20 years ago, and the evolution of these layouts up to the most recent solutions or designs based on cyclotrons and fixed field alternating gradient accelerators, are reported. In addition, the newest ideas and their prospects for development are discussed.
