摘要: Using a two-dimensional turbulence model, strong linear correlation is found between density and electron temperature within scrape-off layer fluctuations. This has important implications for gas puff image interpretation two commonly used lines, Dα HeI (587.6 nm). emission responds approximately linearly to proportional changes in the underlying plasma temperature, making relatively straightforward. However, above ∼25 eV, nm) constant with so perturbations may go unseen. (© 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
