Using low-energy (0–25 eV) threshold electron spectroscopy and contact potential difference in vacuum not worse than 2 × 10–8 Pa, oxygen films obtained at 295, 325–1425 (in steps of 50), and 1575 K, including in subsequent heating from the adsorption temperature to 1925 ± 50 K, on the cylindrical surface of a gas-phase tungsten coating 30 μm thick on NbC-1 alloy (Nb – 1% Zr), used as a collector...
The paper presents a comparative analysis of various schemes of thermionic electrogenerating assemblies (EGAs) that convert the heat of a nuclear reactor into electricity. Multielement single-channel EGAs, combining advantages of a single-element and a garland multielement EGA, are quite promising. The problem of high-temperature insulation of emitters in the construction of this EGA is solved by...
