Measurement of electrostatic and magnetic fluctuations in the ZT-40M Reversed Field Pinch (RFP) are used to estimate fluctuation driven transport. Edge electrostatic fluctuations appear to explain edge particle transport, analogously to some tokamak and stellarator observations. However, in contrast to tokamaks, electrostatic fluctuations do not explain the heat flux through the edge. Instead, transport of suprathermal electrons along fluctuating magnetic field lines constitute the major electron heat loss. Ion losses in ZT-40M appear to be dominated by charge exchange.
