Abstract

The cross-field transport coefficients in collision dominant relativistic plasmas have been derived from a relativistically modified kinetic equation by Legendre expansion analysis. The collision integrals; which include the cross section of relativistic Rutherford scattering, are integrated by using the relativistic Maxwell distribution for electrons. The thermal and electrical conductivities. the Peltier, Nernst, Hall, and Leduc-Righi coefficients are obtained for relativistic plasmas. Resistive magnetic field equations consistently coupled with magneto-hydrodynamic (MHD) and kinetic equations are derived. The set of equations can be included in the simulation code which describes magneto-hydrodynamics of plasmas with relativistic energy electrons. The energy relaxation of relativistic electrons and ions in dense plasmas and the properties of nonlinear heat wave propagation in the ultra-relativistic temperature are also investigated. It is found that the ion heating rate is significantly enhanced by the relativistic effects. This feature is essential for off-centre ignition of targets in laser fusion.
