ABSTRACT
Formulations of axisymmetric equilibrium problems are presented in orthogonal flux coordinates with boundary conditions that do not assume fixation of the boundary shape for both levitron-type traps with a plasma-embedded conductor and conductor-free configurations, including a tokamak. Illustrative examples of numerical solutions of these problems are presented. For traps with a conductor, it is demonstrated how the geometry of the equilibrium with an isodynamic magnetic surface can be found using flux coordinates.

    A simple derivation is given of equilibrium equations in flux coordinates in the general case of an anisotropic-pressure plasma. The issue of how to formulate the boundary conditions for these equations is discussed for two types of configurations-a straight system and a system with an internal...

    It is shown that the numerical method (Collocation Method) used here, works quite well, not only for curved cross-sections but also for cross sections with sharp edge in the boundary (e.g., tokamaks with rectangular or squared cross-sections). We calculated numerically, with high accuracy, the...

    By employing a quantum hydrodynamic model for bounded three-component quantum plasmas, two kinds of streaming instabilities due to ion-streaming and dust-streaming are studied. For this purpose, the dispersion relation for the bounded wave in quantum electron-ion-dust plasmas is obtained by...

The magnetic fields measured at the flux conserver are a sum of the magnetic fields from the plasma current and the eddy currents which...
