Abstract
The paper presents the calculations of the physical and energy parameters of nanocarbon structures with the components of a metal-porous cathode active substance. Obtained results match experimental data. It has been experimentally determined that the active substance modified by the sulfoadduct of carbon nanoclusters has an evaporation rate 1.5 times lower than the typical one. Tests of nanocarbon-modified cathodes as part of a travelling wave tube for space applications have shown them to have a durability of 1 740 800 h at a 0.645-A/cm2 current density on collector.中文翻译:
