Physical conditions in reversed field pinches and theta pinches as inferred from simulations
The nature of the transport in certain pinches is investigated by comparing experimental data with computational predictions of the AURORA code. It is shown that anomalous resistivity and anomalous thermal conduction are present during the implosion phase of the ZT-S reversed field pinch, and that as equilibrium is approached the anomalous contribution to the transport coefficients decrease. Evidence is presented indicating that a low density wall emitted plasma occupies the region between the main plasma column and the wall. Simulations of a theta-pinch show that anomalous heating of the ions due to microturbulent fields makes a noticeable contribution to the ion energetics.
