Abstract ： We report our observation of low frequency (LF) density fluctuation of microturbulence in KT-5 tokamak. Broad frequency and wavenumber power spectra are observed. The density fluctuation frequencies are found to be around a few hundred kHz, and at higher frequencies the fluctuation level rolls off as n2 (f) ∝ f -β with β = 1 - 3. The wavenumber power spectrum S(k) can be fitted into S(k) ∝ k-α with a around 3.0.
