Inertial Electrostatic Confinement
The Cathode Space, Where it All Happens
1. The electrodes are initially charged, charge distributed
on surfaces.
2. An anion arrives in the central space. More follow.
The potential is no longer that of a "simple spherical shell".
3. Electrons surround central anions in a shell. First "virtual
electrode" at boundary between anion space and electrons.
4. Second anion shell forms. Second electron shell approximately
at bounds of sphere enclosed by the cathode grid.
