Applied Atomic Collision Physics, Volume 2: Plasmas covers topics on magnetically confined plasmas. The book starts by providing the history of fusion research and describing the various approaches in both magnetically and inertially confined plasmas. The text then gives a general discussion of the basic concepts and properties in confinement and heating of a plasma. The theory of atomic collisions that result in excited quantum states, particularly highly ionized impurity atoms; and diverse diagnostic topics such as emission spectra, laser scattering, electron cyclotron emission, particle beams, and bremsstrahlung are also considered. The book further tackles heating of plasma by energetic particles; the boundary or edge plasma and particle-surface interactions; and the role of atomic physics in hot dense plasmas. Physicists and people involved in plasma and fusion energy studies will find the book invaluable.
