Abstract:
A plasma accelerator arrangement comprising:a) a plasma chamber that is ring shaped and extends along a longitudinal axis, in which a working gas is supplied that is ionized to produce a plasma; b) an electrode arrangement comprising a plurality of electrode for producing an electronic potential difference as an electrostatic acceleration field in said plasma chamber for accelerating positively charged ions over an acceleration section extending parallel to said longitudinal axis; c) an electron beam emitter for introducing a focused electron beam which is in the form of a hollow cylindrical beam; and d) a magnet system for creating a magnetic field comprising a radially inner magnet arrangement comprising a plurality of magnets and a radially outer magnet. Arrangement comprising a plurality of magnets for guiding said focused electron beam inside said plasma chamber wherein said plurality of magnets of both said radially inner magnet arrangement and said radially outer magnet arrangement each have two opposite poles wherein said plurality of magnets are arranged so that extending along the longitudinal axis, like poles are positioned adjacent to each other.
