The equilibrium of an infinitely long, thinElayer under the influence of external and self‐fields is studied. The canonical angular momentum and the total energy per particle are constant in this analysis. The results can be summarized as follows: (1) with complete charge neutralization, as the number of particlesNincreases, theE‐layer radiusRetends toward the valueRe = (RwRc)1/2, whereR wandR care the radii of the outer and inner conducting walls, respectively, (2) the total kinetic energy per particle initially decreases asNincreases; (3) the axial temperature increases withNso as to maintain stability with respect to the tearing mode; and (4) the current per unit length saturates at a value well beyond that required for field reversal.
