Vacuum in Particle Accelerators offers a comprehensive overview of ultra-high vacuum systems that are used in charge particle accelerators. The book's contributors' noted experts in the field - also highlight the design and modeling of vacuum particle accelerators.The book reviews vacuum requirements, identifies sources of gas in vacuum chambers and explores methods of removing them. In addition, Vacuum in Particle Accelerators offers an in-depth explanation of the control of the beam and the beam aperture. In the final part of the book, the focus is on the modelling approaches for vacuum chambers under various operating conditions.
