This is a graduate-level introductory course on the physics, technology, design and operation of particle accelerators. The course will begin with a brief historical introduction to the needs, the concepts and the R&D of various types of accelerators. Contents of the course will include first, the single particle dynamics both longitudinal (acceleration, phase stability) and transverse (steering, focusing, dispersion). Both linear and non-linear motions will be studied and the use of maps will be presented. Next, for beam dynamics (multi-particle dynamics) we first introduce the concept of the emittance and study the various emittance raising or lowering processes. We, then, discuss the effects caused by the charge and current of the beam, namely, space-charge detuning, coherent beam instabilities (wakefield, impedance), and such special effects as beam-gas scattering, intra-beam scattering, Touschek effect, and beam-beam interactions in colliders. Thirdly, the radiative process of the beam (synchrotron radiation) and the beam-radiation interaction will also be studied in detail. Lastly, an interesting and essential topic is the physics and designs of hardware components such as magnets and rf-cavities (both normal and superconducting), vacuum systems, beam diagnostics, manipulations and controls systems, and error effects & corrections will also be discussed. However, depending on time it may not be possible to cover all these topics. On the other hand, if time allows, a discussion of the future prospects of accelerator R&D can also be included. Prerequisites: Classical Mechanics and Electrodynamics, and working knowledge of analytical geometry and calculus. Previous course in "Accelerator Fundamentals" or equivalent is advisable.
