Electron Induction Linacs

Electron induction linacs have been used for over four decades for a variety of applications. As discussed in Chap. 8, these include basic studies in magnetically confined fusion, transport of intense electron beams in various gases, the generation of electromagnetic radiation from free electron lasers, radiation processing of materials and food, and flash X-ray radiography sources.In this chapter we will discuss the basic structure of electron induction linacs, describe the focusing system commonly used and treat the most important instabilities in these machines.
