The invention relates to method and devices for producing stable hot plasma. In particular, the invention can be applied for realizing stable plasma in a thermonuclear reactor to provide energy source for power generation. In the method plasma is confined by pressure of AC magnetic field concentrated in a layer between plasma surface and surrounding conducting shell in which stabilizing feedback on the confined plasma is created by achieving conservation of the AC magnetic flux amplitude. The device for realization of the proposed method comprises a toroidal conducting shell filled with plasma, with AC voltages applied to insulated cuts in the shell made in poloidal and toroidal directions such that said AC magnetic field is created by AC currents in the shell and image currents on the plasma surface. The amplitudes and relative phases of said voltages are rather arbitrary, in particular they can be selected such that the resultant magnetic vector rotates in the plane tangential to the plasma surface with nearly circular polarization exerting nearly time independent magnetic pressure on the plasma.
A method of plasma creation and stable confinement by pressure of AC electric and magnetic fields, with the frequency of said fields such that the size of the confined plasma is substantially smaller than the wave length of electromagnetic wave propagating in vacuum with the same frequency, with polarization of said magnetic field being different from linear, with special feedback arrangement between perturbations of plasma boundary and said electromagnetic field such that said feedback produces a stabilizing effect on said plasma boundary.
A method of producing and confining plasma in which an electric discharge is generated in a gaseous working medium inside a chamber by subjecting said medium to the action of electromagnetic oscillations, with wall of said chamber having a generally toroidal topology, said toroidal topology defining a torus with a hole, a cyclic toroidal direction encircling said hole, and a cyclic poloidal direction generally orthogonal to said toroidal direction, with the frequency of said oscillations such that the minor radius of said chamber is substantially smaller than the wave length of electromagnetic wave propagating in vacuum with the same frequency, with amplitudes of AC magnetic field in said electromagnetic oscillations having nonzero components in the poloidal and toroidal directions inside said chamber in the vicinity of said wall, with said AC magnetic field generated by AC currents driven in said wall of said chamber and by image currents in said plasma.
