摘要: In vacuum arc discharges the current is conducted through vapor evaporated from cathode surface. these devices very dense, highly ionized plasmas can be created any metallic or conducting solid used as cathode. This paper describes theoretical models of performance for several thruster configurations which use plasma sources. analysis suggests that thrusters using sources operated efficiently with a range propellant options gives great flexibility in specific impulse. addition, efficiency production appears to largely independent scale because metal within few microns electron emission sites, so this approach well-suited micropropulsion.
