    • 专利摘要:
    A multipole plasma pinch method and apparatus produces hot magnetically confined z-pinch plasma with a plurality of z-pinch current channels arranged so as to generate a multipolar magnetic field and at least one hyperbolic magnetic axis within the plasma space roughly enclosed by the channels, forming thereby a region of average magnetic well in a region of nested closed plasma magnetic surfaces surrounding the plasma current channels, when the magnetic field component in the direction of the hyperbolic axis is also made to be substantially zero in the vicinity of the hyperbolic axis. The multipole pinch invention may be operated so that q and field reversal take place within the plasma, and the plasma so produced closely approximates known theoretical stability conditions. The well-producing hyperbolic axis of the present invention is produced effectively by replacing the solid conducting rings of prior art multipole plasma confinement devices by z-pinch-like toroidal current channel loops of plasma. The plasma Is formed inside a vacuum chamber and an electrically conducting shaping sheel assembly, whose noncircu- lar poloidal cross section imparts the desired shape to the plasma. The shape of the plasma may be maintained and/or adjusted by means of electrical currents driven through appropriately distributed external conductors.

    专利说明:

    two current channels 1 and 2, each of which is represented by an observatory field, and all together the opi form a multi-field configuration with at least one hyperbolic magnetic axis 3. Separate 4.
    The invention relates to a study on controlled thermo-nuclear synthesis and can be used to obtain plasma heating and confinement in toroidal thermo-nuclear reactors with magnetic confinement.
    The purpose of the invention is to increase plasma stability and improve plasma retention.
    Fig, 1 shows a plasma cord, cross section; in fig. 2-5 are the possible relative positions of the plasma channels in the process.
    The plasma is created in the form of at least two current channels 1 and 2 located in a common toroidal vacuum volume in such a way that at least one hyperbolic magnetic axis 3 is formed, divided by separatrix 4 into two groups of magnetic surfaces: magnetic surfaces 5 and 6, covering only one of the elliptical magnetic axes 7 and 8, and magnetic surfaces 9, spanning several elliptical axes. Channels 1 and chamber walls are symmetrical with respect to the main toroidal axis 10 and the middle plane 11, "The large radius of the plasma cord may vary regardless of the cross-sectional dimensions, since the plasma is insensitive in this case to long-range. The characteristic sectional shape, the purpose of which is to create parallel current channels 1 and hyperbolic magnetic axis 3, is formed due to the profiled conducting sheath and distributed winding (not shown),
    When plasma is generated and retained in a vacuum chamber filled with gadra of a family, the only current channel and several channels are covered. In the region of this second family, there is a magnetic field that improves the stability of the entire plasma formation. 5 il.
    Thus, using an external vortex electric field, at least two current channels are formed, which are compressed by their own magnetic field as a result of the pinch effect. The initial toroidal field is chosen to be sufficiently small compared to the current field (stability margin q 1), as a result of which
    magnetic flux in the conductive casing channels are formed with a reversed toroidal magnetic field. These channels form a multipole configuration with at least one hyperbolic axis, which has an average magnetic field in the volume surrounding the plasma (in the region of the magnetic surfaces 10 and 11). Having a common magnetic we significantly improves the stability of individual current channels.
