The Acceleration of the Electrons with Distribution Function ƒ ~(v_{0)/v)^δ by Langmuir's Flare Turbulence
Abstract
The process of acceleration of an evolutionary electron beam by Langmuir's flare turbulence is studied in two ways. By means of the diffusion equation in velocity space, Langmuir's turbulence (LT) is described by the spectrum of a strong LT, and secondly, using the Fokker-Planck equation, the LT is described by a soliton gas. In addition, the time in which the original Maxwell distribution function is accelerated to a distribution function is estimated with the aid of a computed spectrum and of the soliton gas under the conditions of the acceleration space. It is suggested that the acceleration space has a filamentary structure, oriented in the direction of the magnetic field and vertically.
