Power Supplies for Synchrotron Accelerators

This book presents the gradual development of particle accelerators that originated from the theory of atomic structure with the disintegration of nuclei in 1911, pioneering findings on radioactivity in 1919, and a few fundamental theories. It describes how the initial energy level has been raised to the present stage of operation and explains how the technological constraints that surfaced during operation over the years were gracefully solved in each step. This book has shared the working experience in a reputed particle accelerator project and tried to highlight various technical difficulties and approaches to find viable solutions to critical problems. The consistent demand for higher energies inspired the researchers to search for various possibilities and concentrate on finding suitable schemes to continue their experiments with particles accelerating at higher energies. This book attempted to encourage students, graduate engineers, researchers, and practicing engineers to focus and engage in new directions with an approach to undertake design, applications, and development of power systems for different patterns of load, power electronics, instrumentation, and control engineering. Practicing engineers working on Particle Accelerator projects may find new aspirations for selecting topics for their research and attempt to develop viable techniques for performance improvements. It is expected to find wide readership amongst science and engineering students and the libraries of colleges, universities, and research organizations may retain this book for the benefit of all because the treatment and presentation of engineering analysis of power supplies for magnet excitation has been taken as far as possible to ground level and dealt differently. It tried to show how simple concepts could initiate revolutionary changes in the development of particle accelerators to inculcate how simple ideas can be explored with confidence to realize a dream and how risks are taken in technological designs after considering all the possibilities of hazards and setbacks with the sole objective of improving performance and cost. The effort to describe a few significant practical achievements in the application of specifically designed electrical engineering equipment, power electronics, and engineering systems selected and developed for particle accelerators may be useful for future projects. This book contains adequate figures and tables with special features like practical illustrations and proper explanations. A new format for presentation will attract the readers and they may find this approach simple to understand the process of particle acceleration and their limitations in working with higher energies. The subject has been presented in such a way that it will be useful for countries intending to develop their particle accelerators.

Introduces particle accelerators to students, researchers, and general public Provides new directions with an approach to undertake design, applications and development of power systems Will be useful to students of Science and Engineering, graduate engineers, and researchers

Autorentext

Pranab Kumar Dey graduated in Electrical Engineering from Faraday House Engineering College, London, and joined Rutherford High Energy Laboratory, Berkshire, England as an engineer. He left Rutherford High Energy Laboratory to pursue postgraduate studies at the University of Nottingham after receiving a scholarship from the Berkshire County Council. But unfortunately, he returned to India without completing his course. He joined the Saha Institute of Nuclear Physics in Calcutta. His keen interest in power electronics and control engineering drew him to join Hindustan Copper Ltd, an integrated copper complex, where he could find different applications of Power Electronics in mining and Process Controls in plants.
