| Abstract: | The Kruskal-Oberman kinetic model is used to determine the conditions for the convective stability of a plasma in a system
of coupled axisymmetric adiabatic open cells in which the magnetic field curvature has opposite signs. For a combination of
a nonparaxial simple mirror cell and a semicusp, the boundaries of the interval of values of the flux coordinate where the
plasma can be stable are determined, as well as the range in which the ratio of the pressures in the component cells should
lie. Numerical simulations were carried out for different particle distributions over the pitch angle. |
