Electron Acceleration in the Aurora and Beyond

Front Cover
CRC Press, 1998 M10 1 - 311 pages
How did electrons in the high atmosphere and space around the Earth come to acquire their speeds and energies?
This intriguing question lies at the heart of understanding how high-energy electrons create the spectacular displays of the ^IAurora Borealis and ^IAurora Australis. Electron Acceleration in the Aurora and Beyond explores the mysteries of these phenomena and others involving the acceleration of electrons in the magnetosphere, in the solar wind, at the Sun and in the Cosmos.
This book presents a new approach to understanding this fascinating subject by treating the acceleration medium as a plasma. Using this new insight we can see that electron acceleration may well be caused by waves rather than steady potential differences. This unique approach is clearly explained in a lively and engaging style.
Quantitative formulae, experiments, practical demonstrations and computer programs enable us to investigate for ourselves how the model works. The theory is further illustrated by comparing acceleration in space with particle accelerators in the nuclear physics laboratory (and even on the sports field!)
Questions and exercises with answers are supplied to stimulate further thinking.
^IElectron Acceleration in the Aurora and Beyond is a thought-provoking book for graduate and post-doctoral space scientists.
