Confinement scaling laws for the conventional reversed-field pinch

A series of high resolution, 3D, resistive MHD numerical simulations of the reversed-field pinch are performed to obtain scaling laws for poloidal beta and energy confinement ar Lundquist numbers approaching 10(6). Optimum plasma conditions are attained by taking the transport coefficients to be classical, and ignoring radiation losses and resistive wall effects. We find that poloidal beta scales as beta(theta) proportional to I-0.40 and that the energy confinement time scales as tau(E) proportional to I-0.34 For fixed I/N, with aspect ratio R/a = 1.25.
