Description
Summary:Advances in heterodyne receiver array technology coupled with a simplified optical design have resulted in significantly expanded plasma coverage and enhanced sensitivity, while simultaneously reducing the local oscillator power levels required to pump the imaging mixer arrays. Details of the next generation plasma imaging concept and its application on the DIII-D tokamak are discussed. Additionally, details of imaging technologies applied on the redesigned TEXTOR ECE imaging system are provided.
