The Physics Society of Iran Iranian Journal of Physics Research 1682-6957 7 2 2019 11 26 Determining of electron temperature profile on the cross section of a Tokamak, using ECE technique Determining of electron temperature profile on the cross section of a Tokamak, using ECE technique 107 111 572 FA M. Hosseinpour A. Anvari M. Ghorannevis Journal Article 2019 11 26  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.  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.
