Abstract

For measuring a turbulence in a high-temperature nuclear fusion plasma, two backscattering systems have been developed in the Large Helical Device (LHD). The Ka-band and U-band Doppler backscattering system have been designed for measuring the ion Larmor radius scale turbulence. Because of the turbulence profile measurements, a microwave frequency comb is used as a source. The W-band backscattering system is designed for measuring the electron Larmor radius scale turbulence.
