Inertial Electrostatic Confinement

The Cathode Space, Where it All Happens:  A More Rigourous Explanation.  Hirsch [5].

Normalized potential density as a function of normalized radius in the cathode space .  Each maximum  and minimum is a "virtual electrode."

Ion density of the same radius.

Note how the highest ion density corresponds to the lowest potential.  This is appropriate considering that it is the cathode potential that is the normative factor vs. anion distribution.
