Simulations of the ZT-S reversed field pinch

The implosion and approach to equilibrium of ZT-S reversed field pinch is studied numerically using the Los Alamos Scientific Laboratory one-dimensional hybrid code ''aurora.'' The effects of classical and anomalous transport, impurity radiation, ion-electron thermal equilibration, and wall emission of plasma are considered in the calculations. Simulations of the implosion which assumed classical transport do not agree with the measurements. However, an accurate simulation of both the magnetic field and electron temperature evolution is obtained with anomalous transport and 0.7% oxygen impurity. As equilibrium is approached, the anomalous terms in the transport coefficients decrease and the values of these coefficients become closer to their classical values
