Abstract The small scale density fluctuations in the interior of HT-6M Ohmic plasma have been studied by CO2 laser collective scattering system in deuterium discharges covering a range of neqa (chord-average density times safety factor at the limiter) and energy confinement time. The relative density fluctuations level in the interior is inversely proportional to the toroidal magnetic field and average density, and the energy confinement time TE decreases with the fluctuation level increasing in the region where TE linearly increases with neqa and satisfies the Goldston scaling Jaw. It is suggested that the microturbulence in the interior zone is responsible for anomalous transport in tokamaks.
