Observation of the ETG mode component of tokamak plasma turbulence by the UHR backscattering diagnostics

Year: 2007

Type: article

Abstract: A fine scale drift wave mode possessing unusually high frequency 2–3 MHz and radial wave number is observed using the correlative upper hybrid resonance backscattering technique at the FT-2 tokamak under conditions when the ETG mode should be unstable. The radial wave number spectrum of turbulence is measured and shown to be maximal at values 120–170 cm −1 corresponding to the largest ETG instability growth rate.
