Abstract

Technology advances have made possible the visualization of electron temperature profiles and fluctuations inside the core of high temperature plasmas via a two-dimensional passive millimeter wave imaging system. The electron cyclotron emission imaging (ECEI) system concept and configuration are briefly described. Advanced technologies such as frequency selective surfaces band-stop filter, planar Schottky diode mixer arrays, wide bandwidth IF electronics, and imaging optics are presented.
