Energy Loss of Ions by Collisions with Magnetized Electrons
Abstract
The interaction of ions with electrons in the presence of an external magnetic field is a basic process for the description of the transport properties of a magnetized plasma, as e.g. the energy loss of ions to the superimposed electron beam in the electron cooler of a storage ring. But a comprehensive description of binary collisions of ions and electrons in the presence an external magnetic field has still to be established. Here, we recently achieved some progress by calculating the energy transfer in binary ion-electron collisions both by fully numerical classical-trajectory- Monte-Carlo (CTMC) simulations and by perturbation theory. These two techniques and some first results are presented and discussed, in particular the strong dependencies of the energy loss on the direction of the ion motion with respect to the magnetic field and on the anisotropy of the velocity distribution of the electrons.
