An introductory text on the physics of charged particle acceleration and transport, designed for senior and graduate courses in accelerators, nuclear physics, particle physics, ion implantation and electron microscopy. Equal emphasis is given to low energy and high energy accelerators, so that the material is relevant to a wide variety of applications. The book treats finite difference methods and analog methods and shows how to use analytic methods to solve Laplace's Equations. In addition it provides a detailed discussion of the role of ferromagnetic materials in accelerators, and a review of ferromagnetic materials and permanent magnets. A unique review of high voltage phenomena and pulsed power circuits - vacuum breakdown, Marx generators, transmission lines, pulse forming networks and pulsed beam diagnostics is presented. This is the only text to present material on linear induction accelerator.
