Scenario of Pinch Evolution in a Plasma Focus Discharge

Original language description

In this paper, the possible evolution of the pinched plasma column is presented following from the results of the temporally resolved measurements using magnetic probe, interferometry and neutron diagnostics performed on the plasma focus PF-1000 device with deuterium as the filling gas. Together with the discharge axial current about 1.5 MA a toroidal current component of the order of 100 kA was estimated in the toroidal, helical, and plasmoidal structures formed within the dense plasma column. The massinside these structures increases due to injection of the plasma from the neighborhood regions with a higher pinching pressure. This injected plasma increases the intensity of the internal magnetic field, probably through turbulent motion and magnetic dynamo effect. The neutrons from the D-D fusion reaction, produced during the formation and decay of plasmoidal structures and constrictions, are accompanied by the changes of the axial component of the magnetic field. Then, the transforma
