The probability distribution function Pn(n) of the particle density at the edge of several magnetic fusion devices, including tokamaks, stellarators, and linear devices, is known to be strongly non-Gaussian. In this paper experimental results from RFX reversed field pinch (RFP) [G. Rostagni, Fusion Eng. Des. 25, 301 (1995)] are presented, confirming the universal shape of Pn also for RFP’s. An explanation for the form of Pn is attempted, on the basis of simple conservation equations. The model result is shown to fit fairly well empirical data in a few different experimental scenarios.
