Abstract

Superconducting radio-frequency accelerating structures are now successfully used in many accelerators. Their applications cover a wide spectrum: heavy ion linacs, recirculating electron accelerators, as well as circular machines. Their original use was in machines with relatively low beam currents, but today superconducting RF is also proposed for applications with high beam currents. A big development effort has already been done in this field, especially for circular machines. Recently several studies have started for high-current applications in linacs.

This paper describes the special aspects of superconducting accelerating structures, as compared to the classical normal conducting ones and experience gained in existing installations. Their advantages and also their drawbacks will be presented, especially in the light of the proposed high- current linacs.
