Abstract
The correlation integral has been studied in detail for broadband magnetic and density fluctuations observed in the TCA tokamak [Proceedings of the 11th Symposium on Fusion Technology (CEC, Luxembourg, 1981), Vol. I, p. 601]. These studies, which provide information on the correlation dimension ν, 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 (ν>10), or with a nonstationary state for which the concept of the correlation dimension has no meaning.Keywords
