Abstract: Fluctuations of the density in a transient process at electron-cyclotron heating have been measured by the methods of backscattering and small-angle scattering of gyrotron radiation by fluctuations of the plasma density. Estimates have indicated the increase and decrease in the turbulent heat fluxes at the switch-on and switch-off of additional electron-cyclotron heating, respectively. The possibility of excitation of vortices of drift waves and their relation with fast anomalous heat transport at electron-cyclotron heating has been discussed.
