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.

具有高耐久性的纳米碳改性金属多孔阴极，可用于微波设备

摘要

本文介绍了具有金属多孔阴极活性物质成分的纳米碳结构的物理和能量参数的计算。获得的结果与实验数据匹配。通过实验确定，由碳纳米团簇的磺基加合物改性的活性物质的蒸发速率比典型的低1.5倍。作为行波管的一部分，用于太空应用的纳米碳改性阴极的测试表明，它们在集电器上的电流密度为0.645-A / cm ²时具有1 740 800 h的耐久性。
