Course Overview
The graduate/senior undergraduate level course focuses on the fundamental physics and key concepts of modern particle accelerators. The course is intended for graduate students and advanced undergraduate students who want to familiarize themselves with principles of accelerating charged particles and gain knowledge about contemporary particle accelerators and their applications.
It will cover the following contents:
 History of accelerators and basic principles (eg. centre of mass energy, luminosity, accelerating gradient, etc)

Course Description
 Introduction to accelerator physics
You will have a glance into the history of accelerators and will learn about a variety of accelerators from electrostatic TVtubes to gigantic atom and nuclear smashers. Basic figures of merit will be introduced (center of mass energy, luminosity, accelerating gradient, etc.) You will learn general principles behing linear accelerators and circular accelerators, their relative advantages and disadvantages.
 Radio frequency cavities, linacs, superconducting RF accelerators
This part of the course will be dedicated to physics and technology of accelerating structures. You will learn basic principles of using radio frequency electromagnetic fields to accelerate particles to very high energies. Different types of accelerating structures will be introduced. You will also learn about brand new direction in linear accelerators – socalled energy recovery linacs. As many modern accelerators are based on superconducting RF (SRF) technlogy, you will learn fundamentals of the SRF accelerators and their advantages over conventional (normal conductoing) RF accelerators.
 Linear transverse beam dynamics
This part of the course will be dedicated to detailed description of linear dynamics of particles in accelerators. You will learn about similarity of particles motion to an oscillator with timedependent rigidity, matrix optics of various elements in accelerators, equation for beam envelopes and stability of periodic (circular) motion of the particles. Here you find a number of analogies with planetary motion, including oscillation of Earth’s moon. You will learn some “standards” of the accelerator physics – betatron tunes and betafunction and their importance in circular accelerators.
 Nonlinear transverse beam dynamics
This lecture will open door in fascinating and neverending elegance and complexity on nonlinear beam dynamics. You will learn about nonlinear resonances, which may affect stability of the particles and about their location on the tune diagram. You will learn about chromatic (energy dependent) effects, use of nonlinear elements to compensate them, and about problems created by introducing them. Some of traditional perturbation theory methods will be introduced during this lecture.
 Longitudinal beam dynamics
If you were ever wondering why Saturn rings do not collapse into one large ball of rock under gravitational attraction – this where you will learn of the effect socalled negative mass in longitudinal motion of particles. You will also learn about socalled synchrotron oscillations, which are have a lot of similarity with pendulum motion. One more “tunes” to remember about  synchrotron tune.
 Radiation effects
Charged particles going around an accelerator do radiate when their trajectory is bent – hence, there is entire range of topics arising from this fact. It goes from such effect as radiation damping of the particle oscillations, quantum excitation of such oscillation to the use of this extraordinary radiation as cuttingedge research tool. We will look both into positive (usefulness of synchrotron and FEL radiation) and negative (limiting the energy of electron storage rings) aspects of this natural phenomenon.
 Accelerator applications
We will devote this part of the course to the discussion of variety of accelerator application, among which are accelerators for nuclear and particle physics, Xray light sources, accelerators for medical uses, etc. You will also learn about future accelerators at the energy and intensity forntiers as well as about new methods of particle acceleration.
