# CME Structure and Particle Acceleration

## TL;DR

This paper explores the structure of coronal mass ejections and the mechanisms of particle acceleration, emphasizing the role of free electrons, electric fields, and magnetic field induction during solar eruptions.

## Contribution

It introduces a model linking ejection structures, free electron effects, and particle acceleration processes in CMEs.

## Key findings

- Ejection-image structures differ between chromospheric and coronal observations.
- Excess free electrons from Compton scattering create an electric field that accelerates particles.
- Accelerated particles induce magnetic fields, influencing CME dynamics.

## Abstract

The differences of the ejection-image structures in the chromospheric lines and the coronal continuum are considered. The outer, more diffusive scattering envelope of the ejection seems to be produced by the excessive free electrons due to the Compton effect. The resulting electric field accelerate the particles while the hard radiation is acting. The directed motion of the accelerated particles induces the magnetic fields.
