Addresses the topics vital to understanding high-power accelerators and high-brightness charged particle beams. Presents a unified description of charged particle beams that is detailed enough for use as a text and comprehensive enough to stand as a reference. This treatment of particle beam physics prepares students to read the literature and to use accelerators effectively. Describes the basic ideas behind modern beam applications such as stochastic cooling, high-brightness injectors and the free electron laser. Designed to furnish students with the critical thinking skills necessary for the simplifications and problem-solving insights unique to collective physics problems. Serves as an independent reference or as the companion book to Principles of Charged Particle Acceleration to provide a programmed introduction to the field of particle acceleration.
