Diffusion and transport in collisional magnetised plasma with temperature anistropy

Summary form only given. The collisional kinetics leading to the analytical derivation of the cross field diffusion transport coefficients in a two component singly charged (electron-ion) magnetoplasma having diffusion across the field lines is studied at the onset of an induced anistropy in plasma temperatures where T/sub ||/ and T/sub /spl perp// represent the components of temperature along the magnetic field direction and the directions perpendicular to it respectively. The modified results agree with early isotropic result of Rosenbluth and Kaufman in the limiting approximation. It is found that E/sup /spl rarr///spl times/B/sup /spl rarr// the drift velocity and thermoelectric coefficient (/spl lambda/) remain unaffected due to anisotropy in temperature where as both the electrical resistivity (/spl eta//spl perp/) and thermal conductivity (K) significantly decrease with increase in the thermal ratio (T/sub ||//T/sub /spl perp//). In the isotropic limit (V/sub 0/=0), the above results are readily recovered from early works. In addition the current density is found to be diminished owing to anisotropy in temperature; modified transport coefficients at the onset of temperature anisotropy are derived.
