Pulse power: Applications to accelerators

In this paper we discuss the potential role of pulse power technology for future high gradient accelerators. Compared to present day pulse power sources the requirements are quite modest and, with the exception of a detailed testing of high repetition rate systems, all components have been tested over several years. We review pulse power technology and its use in collective acceleration of ions and electrons. An account is presented of a new concept for collective electron acceleration through the parametric excitation of fast waves on beams. A summary is given also of achievements in the generation of high power microwave signals, and a discussion presented of structure requirements to take full advantage of the newly evolving ultra high power sources.
