This report covers progress made during the three-month period from October through December 1980. During this period, significant accomplishments include: (1) continuing stable output from the combustion life test of the one-inch diameter hemispherical silicon carbide diode (Converter No. 239) at an emitter temperature of 1730 K for a period of over 4200 hours; (2) construction of four diode module completed; (3) favorable results obtained from TAM combustor-gas turbine system analyses; (4) a FERP work function of 2.3 eV was obtained with the W(100)-O-Zr-C electrode; and (5) the average minimum barrier index of the last six research diodes built with sublimed molybdenum oxide collectors was 2.0 eV.
