Thermal and electrical characteristics of thermionic converters under combined electrode heating

摘要

An experimental procedure for studying the thermal and electric characteristics of a single-element thermionic converter under combined heating of the electrodes is proposed (direct heating by thermal radiation from an electric heater plus heating of the emitter by the reverse cur-rents of the collector). The I-V characteristics of the converter are studied under various operating conditions and at different lengths of the reverse heating current pulse. (C) 2004 MAIK "Nauka/Interperiodica".
