- Аннотация: The nanocrystalline graphite (NCG) is an advanced field emission cathode material has been assessed to introduce an alternative technology for carbon nanotube (CNT) cathodes as a source of electron beam in spacecraft neutralizers compensating the ionic charge of small electric propulsion (EP) thrusters plume. Important advantage of the NCG cathode material for use in neutralizers is its ability to withstand higher oxygen content in ambient gas. In particular NCG cathode readily survives the lasting operation in atmospheric air at pressure of 10-4 Torr without cathode emission degradation.
