ELECTROSTATIC ION ACCELERATOR SYSTEM Russian patent published in 2014 - IPC H05H1/54 

FIELD: physics.

SUBSTANCE: electrostatic ion accelerator system having an ionisation chamber (IK), which has a beam exit opening on one side, in a longitudinal direction, an electrode system comprising an anode system (AN) and a cathode system (KA), which generates an electrostatic field in the ionisation chamber directed in the longitudinal direction, wherein the anode system lies opposite the exit opening at the base of the chamber. The anode system gives off a predominant part of the lost heat that occurs in it to the ionisation chamber (IK) as heat radiation (WS), and a neutral working gas is fed into the ionisation chamber and positive ions are ionised therein. The ion accelerator system forms a spacecraft drive; the magnetic system surrounding an ionisation chamber forms a magnetic field in the ionisation chamber; a heat radiation reflecting device has a reflecting surface with radiation capacity which is less than or is preferably at most half of the radiation capacity of the front surface of the anode facing the ionisation chamber.

EFFECT: simple design.
