Abstract :
We have developed an electron cyclotron emission (ECE) radiometer to measure the radial electron temperature profiles. Before installation of this system on KSTAR, we installed a part of this system on LHD, and confirmed that acquired signals are in good agreement with those provided by the Michelson spectrometer.
