Transport Coefficients of Plasmas in a Magnetic Field

The electric and the thermal conductivities, and the coefficient of the thermal diffusion of plasmas in a magnetic field are calculated under the assumption that the mass ratio m 2 / m 1 is considerably smaller than unity, where m 1 and m 2 are masses of an ion and an electron, respectively. Thereby the terms of the order \((m₂/m₁)1/2\) are retained considering the application to the deuterium plasma, but the higher order terms than those are neglected. For various strengths of the magnetic field, these coefficients are evaluated by the Chapman-Enskog method up to the 6th approximation, and the convergence of this method is examined. The probable error of our approximation varies from 0.1% to 10% with the strength of the magnetic field.
