COLLECTIVE ASPECTS OF BREMSSTRAHLUNG EMISSION AND ELECTRICAL CONDUCTIVITY IN A PLASMA

Abstract

The Bremsstrahlung spectrum and the a.c. electrical conductivity of a plasma is calculated, by classical methods, from a model in which the electrons interact with the plasma as a whole, and not with individual particles. The Fourier expansion of the particle density is employed for calculating the time dependent electrical field at the position of a moving electron, and the Fourier coefficients of the electrical field are used for calculating the Bremsstrahlung emission and the conductivity. The method clearly exhibits the relation between these two quantities, and gives a rigorous expression for the cut-off parameter pmax as a function of the Debye shielding length, the electron mean free path, and the average particle separation.
