Book Description
Intense particle beams may be subject to coupled-bunch instabilities that would grow at rates greater than the bunch oscillation frequencies. The suppression of the growth requires both reduction of the driving impedances and active feedback of bunch motions. The shunt impedances of higher-order cavity resonances can be reduced by passive dampers and the beam impedance within the band of the fundamental resonance can be reduced by rf feedback around the cavity and power amplifier. The feedback of bunch motions composed of numerous coupled-bunch modes requires broad-band systems for which the amplifiers are costly. Examples proposed for electron storage rings are presented. 10 refs, 5 figs.

Book Description
This volume contains the proceedings of the Topical course on Frontiers of Accelerator Technology, jointly organized by the CERN Accelerator School, the KEK Accelerator School and the US Particle Accelerator School. It was held at Maui, Hawaii, November 3-9, 1994. The purpose was to disseminate knowledge on the latest ideas and developments in the technology of particle accelerators by bringing together world known experts and younger scientists in the field. It was intended for individuals with professional interest in accelerator physics and technology, for graduate students, for post-docs and for those working in accelerator-based sciences.The motivation to conceive and build accelerators comes from a most fundamental need of man — to understand and control the world around us. With beams and their associated accelerators, scientists and engineers can gain understanding of the nature of matter and modify matter not possible by other means. Areas already influenced by the developments in accelerator technology are high energy and nuclear physics, atomic and molecular physics, condensed matter physics and the biological sciences. There is also a growing number of applications in medicine and industry. The program was as follows: lectures in superconductivity, magnets, RF, feedback, instrumentation, high power sources, beam stability and novel accelerator techniques; seminars on accelerator applications, the role of government and industry, and perspectives on future technology; round table: the high energy accelerator frontier; four short courses, each including 8 hours of lectures, problems and tutorials on superconducting magnets, superconducting rf, instrumentation and linacs.This book aims to summarize all the currently available knowledge on the technology driving the development of particle beams for science, medicine, and industry. It is the most up-to-date and unique collection of information on this technology presently available.

Book Description
This book provides a comprehensive treatment of intensity dependent particle beam instabilities in accelerating rings. Written for researchers, the material is also suitable for use as a textbook in an advanced graduate course for students studying accelerator physics.The presentation starts with a brief review of the basic concept of wake potentials and coupling impedances in the vacuum chamber followed by a discussion on static and dynamic solutions of their effects on the particle beams. Special emphasis is placed separately on proton and electron machines. Other special topics of interest covered include Landau damping, Balakin-Novokhatsky-Smirnov damping, Sacherer's integral equations, Landau cavity, saw-tooth instability, Robinson stability criteria, beam loading, transition crossing, two-stream instabilities, and collective instability issues of isochronous rings. After the formulation of an instability, readers are provided a thorough description of one or more experimental observations together with a discussion of the cures for the instability.Although the book is theory oriented, the use of mathematics has been minimized. The presentation is intended to be rigorous and self-contained with nearly all the formulas and equations derived.

Book Description
This book offers the first strong evidence of the existence of CP violation in neutral B decays extracted from sophisticated B factories in the US and Japan. It also holds out the expectation of rare B decays and D, K physics in the near future. In addition, new physics beyond the Standard Model is described. Both experimental and theoretical points of view are given.

Book Description
The idea of colliding two particle beams to fully exploit the energy of accelerated particles was first proposed by Rolf Wideröe, who in 1943 applied for a patent on the collider concept and was awarded the patent in 1953. The first three colliders — AdA in Italy, CBX in the US, and VEP-1 in the then Soviet Union — came to operation about 50 years ago in the mid-1960s. A number of other colliders followed.Over the past decades, colliders defined the energy frontier in particle physics. Different types of colliers — proton-proton, proton-antiproton, electron-positron, electron-proton, electron-ion and ion-ion colliders — have played complementary roles in fully mapping out the constituents and forces in the Standard Model (SM). We are now at a point where all predicted SM constituents of matter and forces have been found, and all the latest ones were found at colliders. Colliders also play a critical role in advancing beam physics, accelerator research and technology development. It is timely that RAST Volume 7 is dedicated to Colliders.
