This course provides a broad overview of radiation phenomena associated with relativistic particle beams for application in synchrotron radiation and particle colliders. Basic concepts of beams of particles and radiation are reviewed. The principles of synchrotron radiation are introduced. A qualitative understanding is given followed by a comparison of the characteristics of the radiation from bending magnets, wigglers and undulators, and special radiation devices. Tutorials on advanced topics include: quantum synchrotron radiation, beamsstrahlung, radiation damping in storage rings and the Oide effect. We will describe the generation of short x-ray pulses via Thomson/Compton scattering of high power laser beams with relativistic electron beams. We will discuss the relationship of the x-ray pulses to the undulator radiation and derive formulas for the radiation characteristics for a general incident angle based on scattering formalism. We will also discuss resonant scattering of high power broad band laser beams by relativistic heavy ions and derive rate equations for moving ions, gamma ray and x-ray generation and radiative ion cooling. We will give an introduction to free electron laser physics, energy modulation and bunching phenomena, FEL oscillators and amplifiers. Finally, we will discuss a variety of applications, in particular the application of the FEL interaction to slicing out femto-second electron pulses and to optical stochastic cooling. There will be discussion sessions and problem sets will be assigned. Prerequisites: undergraduate-level electromagnetism and classical mechanics.
