Abstract

A new electron cyclotron emission (ECE) antenna was designed and installed outside of torus, when the heating and diagnostics systems were reconfigured in LHD. Its design is based on Gaussian beam optics and consists of two plane and two concave mirrors. The mirror surfaces are defined using the concept of constant phase to improve matching to the corrugated waveguide. The new ECE antenna was used in a 2010 experiment to measure the electron temperature profile and its fluctuations.
