Abstract Text:
We consider an idealized rotating magnetic mirror, omitting temperature variation as well as impurities and such neutral gas effects as charge exchange. With these simplifications, we explore generalized axisymmetric equilibria, determining in particular the two-dimensional structure of the electrostatic potential, which is nonlinearly coupled to the rotation. We point out that the conventional treatment, based on a simple Boltzmann ion density distribution, implies a rotation frequency that is constant along field lines --- the so-called isorotation model. The equilibrium solution derived here, from force balance and Maxwell equations, is not isorotational, thus overturning the conventional picture. After discussing the nature and quality of the resulting confinement, we consider possible applications of our results to confined fusion plasmas and ion mass filters.
