Transport Phenomena in Stochastic Magnetic Mirrors [electronic resource]
Parallel thermal conduction along stochastic magnetic field lines may be reduced because the heat conducting electrons become trapped and detrapped between regions of strong magnetic field (magnetic mirrors). The problem reduces to a simple but realistic model for diffusion of mono-energetic electro...

| 520 | 3 | |a Parallel thermal conduction along stochastic magnetic field lines may be reduced because the heat conducting electrons become trapped and detrapped between regions of strong magnetic field (magnetic mirrors). The problem reduces to a simple but realistic model for diffusion of mono-energetic electrons based on the fact that when there is a reduction of diffusion, it is controlled by a subset of the mirrors, the principle mirrors. The diffusion reduction can be considered as equivalent to an enhancement of the pitch angle scattering rate. Therefore, in deriving the collision integral, the authors modify the pitch angle scattering term. They take into account the full perturbed electron-electron collision integral, as well as the electron-proton collision term. Finally, they obtain the four plasma transport coefficients and the effective thermal conductivity. They express them as reductions from the classical values. They present these reductions as functions of the ratio of the magnetic field decorrelation length to the electron mean free path at the thermal speed V{sub T} = √2kT/m{sub e}. They briefly discuss an application of the results to clusters of galaxies. | |
