Nonlinear Behavior of the Reversed Field Pinch with Nonideal Boundary Conditions.

摘要

The effect of a resistive boundary and/or a distant conducting wall on a reversed field pinch is investigated with a three-dimensional magnetohydrodynamics code. Fluctuations rise with increasing distance between the conducting wall and the plasma. The enhanced fluctuation induced v /times/ b electric field primarily opposes toroidal current; hence loop voltage must increase to sustain the current. 13 refs., 4 figs. (ERA citation 14:003978)
