ECE Imaging System in LHD
Abstract
Electron Cyclotron Emission Imaging(ECEI) is a powerful tool for investigating MHD instabilities and turbulence in magnetically confined plasma. In the LHD, the ECEI system has been developed and successfully obtained two-dimensional images of temperature fluctuations. This paper describes the current V-band and Q-band ECEI systems including developments in their key components. The initial results of the observation of geodesic acoustic mode (GAM) are presented.
