摘要

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.
