Abstract Microturbulence density fluctuations with drift-wave characteristics in KT-5B tokamak were investigated. The density fluctuation power spectrum S(k_⊥) can be fitted into S(k_⊥) ∝ k_⊥^-α, in which α is in inverse proportion to the toroidal magnetic field B_T. Both averaged frequency and width (FWHM) of the frequency spectrum are increasing functions of B_T. The phase velocity from the statistical dispersion is larger for k_⊥ < 20cm^-1 than that for k_⊥≥ 20cm^-1.
