Ebook: Magnetic Field Distribution in the Plasma Flow Generated by a Plasma Focus Discharge

Journal of Experimental and Theoretical Physics, 2014, Vol. 119, No. 5, pp. 910–923.The magnetic field in the plasma jet propagating from the plasma pinch region along the axis of the chamber in a megajoule PF_3 plasma focus facility is studied. The dynamics of plasma with a trapped magnetic flow is analyzed. The spatial sizes of the plasma jet region in which the magnetic field concentrates are determined in the radial and axial directions. The magnetic field configuration in the plasma jet is investigated: the radial distribution of the azimuthal component of the magnetic field inside the jet is determined. It is shown that the magnetic induction vector at a given point in space can change its direction during the plasma flight. Conclusions regarding the symmetry of the plasma flow propagation relative to the chamber axis are drawn.DOI: 10.1134/S1063776114110168
