THE DESIGN AND CONSTRUCTION OF THIN FILM RADIATION THERMOPILES
Abstract
Thin film radiation thermopiles promise substantial improvement in detector performance and construction cost over conventional solid-wire thermopiles when used in space simulation chambers for measuring simulated solar total irradiance. Three types of substrates were used during the investigation of thin film construction techniques: (1) aluminum foil suspended over a channel cut in the heat sink, (2) thin Mylar suspended over a channel cut in the heat sink, and (3) the heat sink containing a channel which is filled with an insulating resin. These substrates provide thermal resistance between active and reference junctions. Sixteen junction thermopiles of bismuth and antimony were vacuum evaporated onto the substrates, and the completed detectors were tested for sensitivity, response time, and resistance to damage caused by temperature cycling over the range from 80 to 440 K.
