A future linear collider will provide the opportunity for precision studies of new physics. There are many design criteria for such a machine, but the key performance parameters are the collision energy and the luminosity. Projects currently proposed utilize very different linac technologies (with RF frequencies ranging from 1.3 GHz to 30 GHz), but all aim for energies above 500 GeV center of mass, and luminosities above 1034 cm-2s-1. To achieve these ambitious goals, the designers will need to use a wide variety of advanced techniques for production, control and preservation of high-intensity, high-energy beams with dimensions measured in nanometers at the interaction point. The specifications of many of the systems, including the sources, damping rings, linacs and beam delivery, go beyond any existing machines, even where comparable systems exist. This course offers an introduction to the accelerator physics of linear colliders. It will provide an overview including the principal systems from the gun to the interaction point, consider particular issues in depth, and will analyze the choices and constraints leading to designs capable of achieving the required energy and luminosity. Prerequisites: an understanding of basic accelerator physics and an utter disregard for practical realities.
