Self-consistent radial electric field in collisional screw-pinches and axisymmetric closed field line configurations in the absence of fluctuations

Abstract

Collisional plasma confined by magnetic fields in a screw-pinch and any axisymmetric, up-down symmetric closed magnetic field line configuration (such as a dipole or a field reversed configuration) is considered, and equations governing the evolution of the self-consistent radial electric field and flow are derived for each case, provided that effects of plasma fluctuations are negligible.
