Generation of High Charge State Metal Ions in an Arc Plasma

Resumo

Generation of high charge state metal ions in arc plasma is investigated and methods of elevation of the average ion charge state are analyzed. To realize multiple ionization of the arc plasma, a strong magnetic field in the arc cathode area, an ark current spike, an injection of a high-current electron beam or a high-power microwave radiation flow into the plasma, and a creation of a short high-current arc are realized. For each method, the main features are considered and the maximum ion charge states are determined.
