Description

Strong spatial asymmetries in the spectrum and magnitude of low-frequency (ω<<ω/sub c/i) density fluctuations have recently been measured in the TEXT tokamak. Large amplitude, narrow-band (as low as Δω/ωapprox. =0.1) modes have been observed on the high-field torus inside in addition to the typical broad-band (Δω/ωapprox. =1) microturbulence which is present throughout the plasma cross section. These narrow-band fluctuations are only detected at the plasma interior, being localized towards the midplane, and are not seen at the edge
