ことを特徴とするイオンエンジン。 In an electron impact cusp type ion engine that generates ions by electron impact, there is a discharge chamber, an ion extraction grid system that accelerates and extracts the ions generated in the discharge chamber, and a hollow space that is a source of electrons to the discharge chamber. An ion source is constituted by a cathode, a propellant supply device that supplies ionized gas to the discharge chamber, and a magnetic circuit for capturing electrons from the hollow cathode and confining plasma within the discharge chamber. An ion engine characterized in that the magnetic circuit within the discharge chamber is made uniform by making the discharge chamber cylindrical and using a permanent magnet for forming a magnetic circuit installed inscribed in the discharge chamber.
