Abstract

PURPOSE:To get rid of necessitation to form a discharge vessel with insulator quarts glass as well as to aim at prevention against breakdown, by setting up an induction coil inside the discharge vessel, while covering this coil with a magnetic field, and preventing it from coming into contact with a plasma coil. CONSTITUTION:When the electron accelerated by an induction coil 6 collides with the Hg gas led into a discharge vessel 2 from a gas intake system 1, ionizing plasma is formed inside a discharge chamber 8. If so, Hg<+> ion is given kinetic energy by accelerating electrodes 3-5 and, after being neutralized by an electron to be emitted out of a neutralizer 7, discharged out, becoming impel lent force for an ion engine. At the abovementioned, the induction coil 6 is installed inside the discharge chamber 8. And, a magnet 9 is set up on a wall of the discharge vessel 2 so as to cause a magnetic line of force inside the discharge 8 to make up a magnetic cusp annular line around the induction coil 6. With this constitution, plasma is prevented from coming into contact with the induction coil 6. :a: Hg gas.

ことを目的とする。FIG. 2 shows the configuration of a conventional RF (Radio Frequency) type ion engine. Gas introduction system 1
The electrons accelerated by the induction coil 61 collide with the Hg gas introduced into the discharge vessel 2 from the inside of the discharge chamber 8 to generate ionized plasma in the discharge chamber 8. Kinetic energy is given by the accelerating electrode, which is neutralized by the electrons emitted from the neutralizer 7, and then released to become the thrust of the ion engine. Since the induction coil 6 is located outside the discharge vessel 2, insulator quartz glass, which allows the magnetic field to enter the discharge chamber 8, is used as the material for the discharge vessel 2. Quartz glass is easily broken and is not preferable when a large-scale ion engine is used. [Object of the Invention] The present invention has been made in view of the above circumstances, and is an RF type ion engine that does not use quartz glass.・The purpose is to provide engines.

Note that parts 1 whose configuration is the same as that of the conventional device will be designated by the same reference numerals and the description thereof will be omitted. When the induction coil 6 is installed in the position shown in FIG. 1, if there is no magnet, the induction coil 6 will come into direct contact with the plasma, which will shorten its life.
