Generating magnetic field pulses in the development of an explosive Alfvén wave instability in a flow-plasma system

  • Published:
Radiophysics and Quantum Electronics Aims and scope

Abstract

The excitation of Alfvén radiation is studied when an explosive instability is developed in a heated gyrotropic plasma penetrated by a monovelocity flow of ionized gas. It is shown that magnetic field pulses are generated in the plasma under certain conditions. The amplitudes of the Alfvén wave harmonics are found and the conditions for stabilization of the “explosion” due to the nonlinear absorption associated with weakly damped Alfvén wave harmonics are specified.
