Abstract
Transport in a realistic reversed field pinch (RFP) configuration is studied numerically for neoclassical and MHD fluctuation transport mechanisms, by Monte Carlo simulation. The results indicate that neoclassical transport due to guiding center drift is one or two orders lower than classical transport due to finite gyro-motion and thus is not important for RFP plasmas. However, the electron diffusion coefficient corresponding to a typical MHD fluctuation configuration of the magnetic Reynolds number S=104, and equilibrium β=8% is about 106 cm2/sec which is two orders higher than the classical transport, and thus is an important transport loss mechanism for RFP plasma confinement.
