On the structure of the boundary layer separating a neutral anisotropic plasma from a magnetic field

The structure of the boundary layer separating a collisionless plasma from a one-dimensional magnetic field has been studied for anisotropic particle velocity distribution functions of the form

,

where F± is a weighting function, H_± is the Hamiltonian, a± is a parameter, p_z is generalized momenta, m± is particle mass, and δ is the Dirac delta function. Charge neutrality was preserved throughout the boundary layer and self- consistent solutions were obtained for particles having two or three degrees of freedom and moving against either a plane or circular boundary. The results were compared with those for the structure of a boundary layer consistent with a cold streaming plasma having a particle velocity distribution of the form
