Study of deuteron motion in a filamentary Plasma-Focus pinch column for different configurations of filaments

The motion of deuterons in dynamical filamentary configurations of a PF pinch column has been studied with a three-dimensional numerical model. Apart from magnetic fields, the motion-induced electrical fields as well as ion-ion and ion-electron collisions have been included in the equations of deuteron motion. Calculations were performed for different numbers of filaments and its spatial distributions under different initial conditions. Energy of ions was assumed to be from 10 keV up to 200 keV The results obtained have shown many possible modes of ion motion and have demonstrated that the current filaments can cause peculiarities observed in the angular distribution of deuterons emitted from the PF pinch column.
