The electron cyclotron emission (ECE) was investigated in IR-T1 tokomak. According to the
electron temperature plasma and its direct relationship with the absorption coefficient, the
absorption conditions were discussed for both first and second harmonic ordinary and
extraordinary modes and electron cyclotron radiation was calculated. The theory of electron
cyclotron emission and absorption coefficient were considered as non-relativistic effects in
low plasma temperature. By examining the area of absorption in condition pc, the profile
of optical depth in perpendicular emission =/2 and the equatorial plane torus were
calculated and the maximum value of optical depth =1.38 was obtained for IR-T1 tokamak.
These results show that the values of optical depth have a direct relationship with electron
density and electron temperature plasma mostly in second harmonic extraordinary mode.
