This book is the first to focus on tokamaks, the principal research tool in controlled fusion research. Beginning with an examination of the tokamak's place in the field and the requirements of working power generation, ensuing chapters cover such topics as plasma physics, properties of the tokamak, plasma heating methods and problems associated with them, and diagnostic methods. The author also provides an appendix on background mathematical and physical theory. Copiously illustrated throughout and designed with an unusually large page size, this easy to use handbook is both a sound introduction and a basic guide to theory, definitions, and equations for workers in plasma physics, nuclear fusion, energy resources, and power systems.
