Fusion reactor

Fusion reactor comprising a reaction zone, a magnetic field with magnetic flux lines surrounding the reaction zone, the magnetic flux lines being curved convexly seen from the reaction zone in the nearer surrounding of the reaction zone,

• an electric potential pot formed by an electric field surrounding the reaction zone for conversion of kinetic energy of ionized reactants escaping from the reaction zone into potential energy thereof and for subsequent return of the ionized reactants into the reaction zone with reconversion of their potential energy into kinetic energy,
• an ion source in an upper area of the electric potential pot distributed over a ringlike-shaped area surrounding the reaction zone, wherein the reaction zone is positioned in a center region of the electric potential pot surrounding the reaction zone, the portions of the magnetic flux lines extending within the electric potential pot in the region between the upper area of the electric potential pot and the reaction zone run substantially perpendicularly to equipotential lines of the electric field forming the electric potential pot, and
• the electric potential pot comprises at least an electrode in its upper area and at least an electrode in its bottom area in the nearer surrounding of the reaction zone being heated to a temperature within an upper part of the temperature range of liquidity of lithium.
