Anomalous temperature relaxation and particle transport in a strongly non-uniform, fully ionized plasma in a strong magnetic field

摘要

In classical kinetic and transport theory for a fully ionized plasma in a magnetic field, collision integrals from a uniform theory without fields are uaed, When the magnetic field is so strong that electrons may gyrate during electron-electron and, electron-ion interactions, the form of the collision integrals will be modified, Another modification will stem from strong non-uniformities transverse to the magnetic field B. Using collision terms that explicitly incorporate these effects, we derive in particular the temperature relaxation between electrons and ions and the particle transport transverse to the magnetic field. In both cases collisions between gyrating electrons, which move along the magnetic field, and non-gyrating ions, .which move , in arbitrary directions at a distance transverse to B from the electrons larger than the electron, Larmor radius but smaller than the Debye l0ngth? give rise to enhancement factors in the corresponding classical expressions of order In (M_(ion)/M_(el)).
