Energy recuperation of positively charged ions

It is important to recuperate the energy of beams of positively charged ions with simultaneous neutralization of their charge, for example, behind the nozzle of an electric rocket engine, into electric power. One of the methods to solve this problem is development and application of energy recuperators of positively charged plasma flow ions, which can be installed near the cutoff of the ERD nozzle. The process of energy recuperation of positively charged ions with simultaneous neutralization of their charge consists in electrostatic inhibition of the concentrated beam of charged particles and their interaction with the energy recuperator multicollector electrodes, which in turn are the charging electrodes of the supercapacitor. It accumulates electrostatic electricity on the elec- trodes of the supercapacitor, which can be used to power the systems of the spacecraft (SC). When positively charged ions interact with multi-collector electrodes, their charge is also neutralized by the action of the electron current com- ing from the double layer of the charging electrode of the supercapacitor. To improve the efficiency of energy recovery of positively charged ions, the volume charge of charged particles is exposed to a low-frequency electric field by an isolated control electrode installed in the cavity of a multi-collector electrode towards the moving ion flow. Development of energy recuperators of positively charged ions and increase of energy efficiency of ERD requires a scientific research based on the construction of models, principles of construction and evaluation of methods of manufacturing of their individual components.
