Abstract
The properties of experimental thermionic converters with emitters made of oxygen-containing single-crystal tungsten are studied. The tungsten is produced by the chloride CVD method. Such emitters not only perform their basic function in the converter but also serve as an “internal” oxygen source. An attempt is made to raise the emitter temperature in order to increase the maximal output of the converter using the new emitter material. The efficiency of applying an oxygen-free single-crystal tungsten collector is contrasted with that when the collector is made of polycrystalline tungsten or Cb-1 niobium alloy.
