THEORY OF ANOMALOUS TRANSPORT IN THE REVERSE FIELD PINCH

The transport coefficient for a magnetized plasma, which has been obtained by the use of the method of self-sustained turbulence, is applied to the reverse field pinch (RFP). The dependence beta(p) proportional to n(3/4)/I-p is obtained (beta(p) is the plasma pressure divided by the poloidal magnetic pressure, n is the plasma density and I-p the plasma current). This result gives an explanation of the experimental observation of the RFP scaling, beta(p) proportional to n/I-p. This theory of anomalous transport unifies the L-mode scaling laws in tokamaks, stellarators and heliotron/torsatrons as well as the RFP.
