Despite the great progress made during this century in the development and operation of particle accelerators, we are, at the moment, facing severe limitations which impede the attainment of very cold and dense beams of charged particles. These limitations are due to the interparticle Coulomb interactions: intrabeam scattering and space-charge effects. Recently, there has been interest in the feasibility of producing a crystalline beam. This is a spatially ordered ensemble of circulating particles having very small velocity fluctuations relative to each other. Such a state may be obtainable from an ordinary warm beam through the application of intense and continuous phase-space cooling (eg. stochastic, electron, laser). Crystalline beams represent the ultimate in the control of space-charge effects. The study, and eventual attainment, of crystalline beams may lead to a variety of other applications, but will certainly provide a deeper insight into the fundmental limitations of storage rings and particle colliders.

The quest for the revelation of the deepest composition of the structure of matter and the nature of the fundamental forces that bind them together is underway, using experiments with colliding hadron beams at the largest energy and luminosity that present and near-future accelerator technology can allow. This book gives the physics motivation of such a collider and discusses the benefits and requirements of the experimental program. Obviously the size of the collider is a major concern, and that is determined by the bending field which is possible to achieve in superconducting magnets; the book includes a discussion on the ultimate expected magnetic field that can be reached. There are also presentations of straw-man designs; in particular, the effects of the synchrotron radiation, which are quite significant at very large energies and large bending fields, are examined, with the possibility of taking advantage of them for the attainment of small beam size and thus luminosity. In addition, detector issues are discussed, especially in relation to the large expected background, the total number of events, and the difficulties of gathering and selecting relevant events. Finally, there is a discussion on the social and political implications of such a project.
