Abstract:

Our knowledge of the most fundamental structure of matter has increased enormously over the past 50 years. We now know that quarks and leptons are the basic constituents of matter, at least at accessible eCollOct30nergy scales. We also know that the electromagnetic, weak and strong forces can be understood to be the result of gauge invariance and spontaneously broken symmetry. In order to bring gravitation into this framework, many theorists have spent enormous efforts on developing string theory. At the present time, the Large Hadron Collider is coming online and we all hope that it will elucidate some of these ideas. We “expect” to discover the elusive Higgs boson, and perhaps supersymmetry and hitherto unrevealed space dimensions. We may even see evidence for the "stringy" nature of matter. These theoretical ideas, and the experiments, are often discussed. However, the accelerator itself often gets little attention. All our knowledge of the most basic level of matter has been due to advances in accelerator science. Accelerators are an amazing union of physics and engineering; the history of advance in particle physics is the history of advance in accelerator science. I will discuss some of the ideas of basic accelerated beam dynamics, and also talk about the status of the LHC itself.
