The thick line represents a marginally stable field for . The marginally stable magnetic field strength at the axis is drawn by a dashed line. ICRH with tuned resonant absorption just outside one of the mirrors can be applied to improve ion end confinement.

Marginally stable magnetic field with straight field lines in the confinement region. Magnetic flux tube cross sections with constant are indicated with ellipses. Resonant absorption of ICRH appears at constant surfaces.

Variations of the electric potential, density, and the magnetic field strength along a flux line. The lower curves show possible density and electric potential profiles, where a sheath potential near the wall is added. The bump where is essential for trapping low energy ions and provide a warm plasma stabilization. The outer region where near and outside the mirror trap is crucial for confining the electrons. A potential sheath depression close to the wall, where quasineutrality does not hold, can confine a majority of the few loss cone electrons that are able to penetrate the mirror trap.
