Abstract

The interaction of non-thermal electrons injected into a flare loop and whistler turbulence in it is investigated. Turbulence generated by an external source is considered with spatial and temporal characteristics similar to those of electron injection; it is assumed that both of these processes occur at the same time and in the same place during energy release in a flash. The peculiarities of the non-thermal electron distributions transformation in energy and pitch angles are revealed, taking into account the reverse effect of electrons on the whistlers’ turbulence. It is established that the power of the turbulence source and the turbulent capture of non-thermal electrons significantly affect the process of additional acceleration. In contrast to the model with a given stationary distribution of Whistler turbulence, in the model with a consistent interaction, there is a significant decrease in the energy density of turbulence, which significantly reduces the efficiency of electron acceleration.
