Effect of finite beta on drift-wave turbulence and particle confinement
Journal Article
·
· Phys. Rev. Lett.; (United States)
This Letter predicts, on the basis of the structure of mode-coupling equations, that if the plasma ..beta.. exceeds the square of the inverse aspect ratio, (a/R)/sup 2/, the cross-magnetic-field diffusion is greatly enhanced by the appearance of convective cells even in the presence of magnetic shear.
