Energy balance in a twotemperature deuterium plasma
Abstract
The energy transfer between the electron and deuteron components of a hot fully ionized deuterium plasma is studied under the following circumstances: (a) the prevailing mechanism is the elastic Coulombian scattering, (b) each charged particle is screened by the surrounding particles of opposite charge at the socalled 'Debye radius', (c) Born approximation is used for estimating the collision crosssection, (d) local thermodynamic equilibrium and Maxwelllike velocity distribution do hold separately for electrons and deuterons. The rate of energy transfer is finally given as an analytical expression in terms of temperatures, particle densities and atomic constants.
