I have two questions about the plasma.
1. Can the plasma sheath be made diffuse enough and cover enough electrode area that the discharge intensity is reduced to the point where metal vaporization is insignificant?
For example can a corona charge be created around the electrodes to create a larger conductive area around the electrodes?
2. The metal ions are much heavier than the deuterium ions. Can the momentum of the metal ions be used to separate them from the pinch?
