Processes of self organization in plasma focus discharges final phase

Current-plasma structures (CPS) in plasma focus discharges besides of pure practical interest from point of view of their influence on compression effects, plasma heating and particle acceleration have also a great physical significance as the striking example of self organization in high current plasma. Study of CPS at the initial and final phases of plasma focus has shown that neutron pulse generated at a so called turbulence state correlates with presence of absence of CPS. In this paper the CPS are investigated at final stage of plasma focus discharge with megampere current. It has been shown that an increase of filling pressure of deuterium gas without changing of bank energy leads to a more clear display of the effect of the filament structures creation (local quasi Bennet pinches-Kvartzhava pinch structures). The criteria and role of various mechanisms which result in a space periodic structure of plasma focus current sheath, the influence of this structure on the subsequent processes (including accelerating mechanism) are analyzed. The corresponding estimations are presented
