Abstract [en]

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 at Lundquist numbers approaching 106. 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 βθ∝I-0.40and that the energy confinement time scales as τE∝I0.34 for fixed I/N, with aspect ratio R/a = 1.25.
