IPC: F03H1/00
Filed: 1993-02-24
Abstract: PURPOSE:To keep the temperature of a magnet below tolerance limits even if an ion engine operates for many hours by providing a charged particle prevention member which is kept at negative potential for a shield case between a discharge vessel and the shield case in the ion engine which is mounted in an artificial satellite. CONSTITUTION:A charged particle prevention net 20 in the shape of net is provided between a discharge vessel 3 and a shield case 1 and is concentric with the discharge vessel 3. The charged particle prevention net 20 is kept at negative potential for the shield case 1.
