This engaging book presents the fundamentals of ion traps and their use in physics, chemistry and their technological applications. Following an overview of the types of traps and their operation, the book explores their key areas of application for the development of new physics, chemistry, or engineering at a level accessible by students. The introductory nature and broad coverage will also make the book essential reading for scientists who wish to understand and explore the use of ion traps in their research. Embracing optical manipulation, entanglement and exploitation in quantum computing, chemical reactivity, atomic clocks and testing fundamental physics this book provides a broad and accessible introduction to the world of ion traps and how our understanding and exploitation of trapped ions is furthering modern science and technology.
