Abstract

137 GHz heterodyne receiver measurements with hollow ceramic HE₁₁ waveguides are being applied to nuclear waste glass melt monitoring of temperature, emissivity, and surface fluctuations/flow in both laboratory and engineering scale melters at temperatures as high as 1500°C. New insights are being provided on molten glass/salt interaction and glass pour dynamics.
