تعیین تغییرات شعاعی و زمانی دمای الکترونهای پلاسما در توکامک IR-T1 با استفاده از تابش سیکلوترونی الکترونها ECE

 In this paper we have used plasma electron cyclotron emissions at the second harmonic frequency of extraordinary mode to determine the temperature profile of the plasma produced in IR-T1 Tokamak. The emissions obtained at different frequencies by a 5-channel heterodyne receiver, have been analyzed to determine the spatial variation of the electron temperature on the plasma cross section. The results have been also used to show the three-dimensional time evolution of the temperature profile during the period of confinement.
