  1. Perspectives of power increasing of arc cesium-oxygen thermoemission converters with tungsten electrodes at increased emitter temperatures

    International Nuclear Information System (INIS)

    Characteristics of experimental thermoemission converters with emitters made of oxygen-containing monocrystal tungsten produced by chloride gas-phase technology were studied. The emitters, besides their main function in the operating converters, played the role of inner source of oxygen. An attempt was made to expand the range of the emitter temperatures towards increase for attaining the maximum output power of the converter using the new emitter material. Efficiency of using the monocrystal oxygen-free tungsten collector compared to collectors made of polycrystal tungsten and niobium alloy Cb-1 was studied
