The Physics of Alfvén Waves

Alfven-Wellen sind Plasmawellen, die als Träger von Energie und Information fungieren. Das Verständnis dieser Wellen ist von großer Wichtigkeit in der Astrophysik, der Physik der Magnetosphäre und Ionosphäre sowie in der Entwicklung von Fusionsreaktoren. Mit diesem Buch liegt jetzt ein Werk vor, das den aktuellen Stand der Forschung auf diesen Gebieten präsentiert. Dabei konzentriert sich der Autor nicht nur auf ideale Alfven-Wellen, sondern geht vor allem auf nichtlineare Effekte ein - ein Gebiet, auf dem Neil F. Cramer als Experte gilt. Obwohl selbst Theoretiker, legt er größten Wert auf die Einbeziehung von Experiment und Beobachtung.

Résumé
Low-frequency wave modes of magnetized inhomogeneous plasmas have been subject to intense study in the last decade because they play important roles in the transport of energy in the plasmas. The "Alfven wave heating" scheme has been investigated as a supplementary heating scheme for fusion plasma devices, and it has been invoked as a model of the heating of the solar and stellar coronae.
This book covers the latest research into the properties and applications of low-frequency wave modes in magnetized plasmas, the Alfven waves and magneto-acoustic waves, in the context of laboratory, space and astrophysical plasmas. In particular, non-ideal effects on the dispersion relation and absorption properties of linear and non-linear waves are included, such as ion-cyclotron effects, friction between the ionized plasma and a background gas of neutral atoms, and the interaction of the plasma with dust particles.
The book also surveys the theory of Alfven and magnetoacoustic waves in inhomogeneous plasmas, as occur in realistic laboratory, space and astrophysical plasmas, with resulting localized wave modes such as surface waves. Waves are considered under a variety of plasma conditions, ranging from cold cosmic plasmas, to hot laboratory and solar plasmas, to the relativistic plasmas around pulsars.
