Electron Temperature Measurement in IR-T1 Tokamak by ECE Diagnostic

Original Paper


A suitable instrument for electron temperature measurement in Tokamak is electron cyclotron emission diagnostic. We used a heterodyne radiometer in Iran-Tokamak-1 (IR-T1) to measure this parameter. This 5 channel system works in K α-band and has a very fast response time and good resolution frequency for IR-T1 tokamak. This receiver was used outside the Tokamak, perpendicular to B t, and with second harmonic of X-mode, variation of electron temperature was measured.
