Abstract

This paper presents development of quasioptical microwave technology for ECE and reflectometry diagnostics in the Large Helical Device (LHD). The ECE for the electron temperature measurement is transmitted with the corrugated wave guide system. Technology for Microwave imaging, such as imaging reflectometry and ECE imaging, has been developed to visualize 3D view of turbulence
