Opis:: In the report the dynamics of the Toroidal Plasmoids formation in a Cavity of the Neck (TPCN) of plasma columns and tubes is described. The study was carried out within the MHD (magnetohydrodynamics) frames and by using the particles method. It was shown that in the fast forming neck of plasma pinch, some observed orthogonal to the current structures could be H-filaments (at the equilibrium state they are θ-pinches). These filaments are supported due to the interaction of the induced (secondary) current with magnetic field of the Z-pinch.

Opis:: In this report we present a first series of tests of the lithium Capillary Porous System (CPS). We suppose that such a system can be used as a first wall in a thermonuclear reactor. The main goal of the presented work was to study the behavior of the lithium CPS in the condition simulating the influence of plasma in various operating regimes of the thermonuclear reactor. The tests were conducted in a Plasma Focus (PF) installation. The preliminary analysis of the received results confirms the high resistance of the lithium CPS to the pulse influence of plasma flows.

Opis:: This paper is devoted to the experimental and theoretical study of plasma current sheath behavior for a low energy plasma focus device operating at a filling nitrogen gas pressure of 3.3 torr, and at a stored energy of 1.2 kJ. Axial distribution profiles of plasma current sheath (PCS) characteristics such as propagation velocity Vz, acceleration az, azimuthal magnetic field induction Btheta, and magnetic force per unit volume Fz/m3 along the coaxial electrodes system was performed from a magnetic probe and miniature Rogovsky coil signals. The experimental results showed that the axial distribution of Vz, az, Btheta and Fz has approximately the same profile and the maximum value of these parameters was detected nearly at a mid-distance of coaxial electrodes system. Theoretical description of PCS dynamics at the axial phase, based on a snowplough, was estimated as a function of discharge time. These data were compared with the received experimental results.

Tytuł:: Nonlinear Excitation of the Non-Wave Perturbations by the Magnetoacoustic Waves in the Non-Isentropic Plasma

Tematy:: magnetoacoustic waves

Opis:: Nonlinear excitation of slow modes by the planar magnetosonic perturbations in a plasma is discussed. Plasma is an open system due to radiation and external heating. This may stipulate enhancement of wave perturbations and hence the acoustical activity of plasma. Plasma is assumed to be a homogeneous ideal gas with infinite electrical conductivity. The straight magnetic field is orthogonal to the velocity of fluid’s elements. Nonlinear excitation of the non-wave modes (that is, the Alfvén and the entropy modes) by periodic and aperiodic planar magnetoacoustic perturbations, is discussed. The sawtooth wave and the small-magnitude harmonic wave are considered as examples of periodic in time perturbations. The conclusions concern acoustically active and thermally unstable flows as well.

plasma focus
Opis:: A global instability theory of pinching plasmas allows us to justify the well-known empirical facts of the use of a mismatched dense plasma focus (DPF) and heavy inert gas admixtures. We assume that an instability of tangential discontinuity is responsible for the instability of a current-carrying plasma column. To inhibit development of a tangential discontinuity in a plasma focus, an array of insulator fibers or metallic wires placed on the anode near the axis of a discharge camera can be used.
