DEPARTMENT OF PLASMA PHYSICS

Researche


  1. The research of gas-discharge non-neutral electron plasma.

    • Dependence of electron sheath characteristics on anode alignment.
    • Influence of the asymmetry of electric and magnetic fields on electron sheath structure.
    • Neoclassical transport of electrons across the magnetic field in case of anode disalignment.
    • Collapse of electron sheath in quasi-neutral discharge regime.

  2. The development of experimental methods for investigation of non-neutral plasma non-uniformities.

    • The method of two electrostatic probe for measuring the non-uniformity trajectories and charges.
    • The method of determination of lateral dimensions of non-uniformity.
    • The diamagnetic and hole methods.

  3. The research of solitary vortex structures in non-neutral electron plasma.

    • Origination and formation of solitary vortex structures.
    • The dynamics of vortex structures in the discharge device of different geometry.
    • Orbital instability of vortex structure.
    • Neoclassical and turbulent transport of electrons across the magnetic field.

  4. The research of the mechanism of creation of electrons of "anomalous energy".

    • Creation of electrons of "anomalous energy" during the formation, approach and orbital instability of vortex structures.
    • Continuous flow of "anomalous electrons" from the vortex structures

  5. Theoretical investigation of non-neutral electron plasma.

    • Nonlinear evolution of non-neutral electron plasma.
    • Diacotron instability of gas-discharge non-neutral electron plasma.
