抄録

The measurement of electron density and temperature from electron cyclotron emission (ECE) is studied using a numerical calculation taking into account the relativistic effect. For the measurement of the electron temperature profile in Large Helical Device (LHD) in order to avoid the relativistic effect of 2nd harmonic ECE at the center and the absorption effect at the outer periphery, the location of the observing port should be at the opposite side of the highest magnetic field point with respect to the plasma center. The measurement of the electron density profile from ECE proposed can be applicable for various electron density profiles in tokamak.
