The worldwide accelerator community is actively involved in the planning of a TeV Linear Collider, LC as the next big high-energy physics facility. This multibillion dollar facility still requires an enormous amount of R&D in many disciplines of physics, engineering and technology to generate, prepare and preserve the extremely high quality of beams required for useful application in high-energy physics. The USPAS feels a great responsibility to contribute to the education and training towards this goal. This course is intended to give the newcomer an overview of the basic functioning of a linear collider, it's components and beam diagnostics methods as well as a confrontation with many issues still to be solved during upcoming R&D. It is our belief that the whole accelerator community should be knowledgeable about this facility, which may very well dominate a significant part of our future. The lectures are complemented with computer-aided simulation studies for the generation and preservation of high-performance electron beams. More in-depth courses on special topics of LCs will be offered at future schools. The course is intended for accelerator as well as high-energy physics scientists and students and interested engineers and technicians with a background in basic accelerator principles and terminology.
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.
