An apparatus for studying the heat characteristics of thin-film photoconductive cells

An apparatus for studying the temperature field distribution in thin-him ph otoconductive cells (PCCs) by LR pyrometry is described. The electric circu it of the apparatus permits automated maintainance of identical conditions for supplying the electric power to the PCCs on insulator substrates in tes ting the properties of several elements, for example, of four optron pairs. The use of substrates made of anodic alumina instead of conventional pyroc eramic ones to prepare thin-film PCCs was shown to greatly reduce the PCC o perational heat load; compared to sapphire substrates, this significantly l owers the cost of technology.
