FIELD: power industry.
SUBSTANCE: invention relates to power industry. An ion engine containing a housing, and a gas discharge chamber and an ion-optic system and a cathode-neutraliser installed on the housing, which are rigidly fixed on the outer surface of the housing, with that, the housing of the ion engine has a toroid shape, with that, the cathode-neutraliser is installed on the central axis of the housing, electrodes of the ion-optic system and the gas discharge chamber has an annular shape, with that, their internal surfaces are rigidly fixed along the perimeter on the internal surface of the housing of the ion engine.
EFFECT: invention allows considerable increase of vibration strength of electrodes, stability of inter-electrode gaps, as well as increase of efficiency.
