This textbook, "Particle Accelerator Physics: Basic Principles and Linear Beam Dynamics," authored by Professor Dr. Helmut Wiedemann, provides a comprehensive introduction to the physics of particle accelerators and particle beam dynamics. The book is divided into two volumes, with the first volume serving as a self-contained introduction for newcomers to the field, covering fundamental principles of particle acceleration, linear beam dynamics, and basic concepts of synchrotron radiation. The second volume delves deeper into advanced topics such as higher-order beam dynamics, Hamiltonian particle dynamics, nonlinear beam optics, and collective beam instabilities. The text is based on lecture notes from various institutions and includes numerous figures and detailed discussions of theoretical concepts and practical applications. It aims to bridge the gap between internal notes from high-energy physics laboratories and accessible educational resources, making it a valuable reference for graduate students, engineers, and scientists in the field of particle accelerators.This textbook, "Particle Accelerator Physics: Basic Principles and Linear Beam Dynamics," authored by Professor Dr. Helmut Wiedemann, provides a comprehensive introduction to the physics of particle accelerators and particle beam dynamics.
