This book deals with recent topics in the field of ion beam cooling. Indications of one-dimensional ordering observed by electron beam cooling of highly charged heavy ion beams, and crystal beams observed by laser cooling at the RFQ storage ring, are presented together with theoretical and computational investigations on these phenomena. The approach to hot ion beam cooling is also discussed, from the viewpoint of application of the beam cooling technique.

This book is especially concerned with fundamental theoretical and experimental aspects of relativistic beam physics, recoil, and cooling phenomena in atomic and ion beams and traps, with emphasis on coherence and collective effects. The central theme is the physics of atomic laser and free electron laser, and the development of a bridge between them through the mechanism of the so-called recoil induced gain mechanism. The links between relativistic beam physics and atomic laser physics are explored. This book is targeted at an audience of non-specialists or specialists in only one of the fields mentioned above. It addresses the following topics: Fundamentals of laser cooling and trapping of atoms: theory and experiments; Quantum optics and atomic coherence effects; Laser cooling of trapped ions; from single ion to ion crystal; Spatio-temporal instabilities in optical systems; Coherence in atom optics; atomic diffraction and interferometry; Optical lattices; nonlinear effects in laser-cooled atoms; Coherent population trapping; Two-level gain and collective recoil-induced effects; Fundamental physics of relativistic particles beams; High-gain free electron laser: theory, experiments and projects; Cooling of ion beams in a storage ring; Experiments on dense laser-cooled stored ion beams.

The frontiers of beam research point to increasingly high energy, greater brightness and lower emittance beams with ever-increasing particle species. These demands in turn have triggered a rapidly growing number of beam phenomena that involve quantum effects. Concurrently, the violent accelerations which are becoming available through novel accelerator research may, perhaps, help to investigate fundamental physics associated with general relativity. In view of these exciting developments and the important role they may play in the next century, the world's first conference on the 'Quantum Aspects of Beam Physics', held at Monterey, California, in January 1998, attracted a broad spectrum of experts from beam physics, particle physics, laser science, astrophysics, condensed matter physics, nuclear and atomic physics. At the end of the meeting, a new term 'quantum beam physics' was coined.This book collects together the excellent reviews and papers on new advances in the field which were presented during the workshop. It should be a valuable reference to all physicists interested in the frontiers of quantum beam physics.

This volume is a compilation of significant papers by leading scientists exploring exciting frontiers of physics. It presents the latest results in well-defined fields as well as fields represented by the interfaces between mainstream sciences.G 't Hooft is the 1999 Nobel Laureate in Physics and A Richter is the Stern-Gerlach prize recipient of 2000.
