As I understand the the fusor operation,
plasma heads towards the the central grid
rushes past and hopes to fuse. The grid heats
up because of plasma striking the grid
as it enters and leaves the fusion area.
Does anybody have a idea of what % of heating
is caused by plasma striking the grid on the
way in and the way out. Could not a third
grid covering the inner grid be added to partly acclerate the plasma but primary to have lower
energy plasma stike this grid rather than the
central grid for incoming plasma. This would
I hope would focus the plasma to avoid hiting the primary grid. Ben.
