The correlation integral has been studied in detail for broadband magnetic and density fluctuations observed in the TCA tokamak [Proceedingsofthe11thSymposiumonFusionTechnology(CEC, Luxembourg, 1981), Vol. I, p. 601]. These studies, which provide information on the correlation dimension &ngr;, have shown no evidence for a low‐dimensional attractor. It has therefore been concluded that the broadband fluctuations are associated either with a high‐dimensional system (&ngr;>10), or with a nonstationary state for which the concept of the correlation dimension has no meaning.
