    "abstract": "The Probability Distribution Function (PDF) Pn(n) of the particle density at\nthe edge of several magnetic fusion devices, including tokamaks, stellarators,\nand linear devices, is known to be strongly non-gaussian. In this paper we\npresent experimental results from RFX Reversed Field Pinch [G. Rostagni, Fus.\nEng. Design 25, 301 (1995)], confirming the universal shape of Pn also for\nRFP\u0027s. An explanation for the form of Pn is attempted, on the basis of simple\nconservation equations. The model result is shown to fitted fairly well\nempirical data in a few different experimental scenarios.",
