Anisotropic Coulomb effects on bremsstrahlung emission from bi-Maxwellian plasmas

Abstract

Anisotropy of the electron-ion bremsstrahlung spectrum from bi-Maxwellian plasmas is investigated including the Coulomb correction effects. The Coulomb correction effects on the bremsstrahlung emission rate for T∥>T⊥ are found to be more significant than those for T∥<T⊥ where T∥ and T⊥ are temperatures for the parallel and perpendicular motion to the magnetic field. An increase of the parallel or perpendicular temperature causes a decrease of the Coulomb effects on the bremsstrahlung emission power.
