Electron cyclotron resonance heating on CT-6B tokamak

An electron cyclotron resonance heating experiment has been performed by using a gyrotron system for the fundamental and second harmonic resonance heating on CT-6B tokamak. Obvious changes are observed in soft x-ray radiations, electron cyclotron emission, displacement of plasma column, impurity line radiations, and bremsstrahlung radiation when heating pulse is injected, indicating an increase of the plasma electron temperature.
