The Physics of Fluids, 1961
The magnetohydrodynamic stability of an infinitely conducting incompressible plasma, in the shape of an infinitely long circular cylinder within an external conductor, compressed by external Bθ and Bz against internal Bz, is investigated in the circumstance that the plasma has an angular velocity about the z axis of the cylinder.

Axial structure in a theta-pinch plasma
The Physics of Fluids, 1973Axial irregularities in a θ-pinch plasma are observed during the initial breakdown and main discharge phases. The structure is associated with a gas-breakdown effect. Wavelengths and growth times are consistent with the development of instabilities associated with thermal waves.

Journal of the Physical Society of Japan, 1958
A new process of pinching a plasma column is treated theoretically. A column of plasma with no longitudinal current can be pinched by an external magnetic field parallel to the column; and the plasma thus pinched will not show any instability. The process depends on the effective value of γ, the ratio of specific heats.

IEEE Transactions on Plasma Science, 1993
The Z-pinch is formed in a low-pressure pulsed discharge between two conical electrodes having an axial symmetry. In such a configuration, a plasma jet can be created. Results of a jet study by schlieren and interferometric diagnostics are used to design apparatus with a similar electrode configuration, in which the Z-pinch effect drives the plasma ...

Plasma jet formation in x-pinch plasmas
AIP Conference Proceedings, 2001Plasma formation in a x-pinch-formed from two 10 μm Al wires at a current of 100 kA- was studied by using a two frame Mach Zender interferometer. It was observed that the plasma column that forms on the axis of the x-pinch, does not come entirely from the coronal plasma from the limbs but rather from the plasma formed at the crossing point region.

Pinching Processes in Semiconductor Plasmas
Journal of the Physical Society of Japan, 1970Adiabatic compression model for the linear pinch in avalanching n -InSb is studied experimentally. The pinching radial velocity and the final pinched radius are determined from the cross sectional dependence of the pinch time, and compared with the theory.

Turbulent pinch in whole-plasma simulations of a dipole-confined plasma
Physical Review E, 2020Whole-plasma simulations of turbulent transport and upgradient plasma pinch are presented in a dipole magnetic geometry relevant to the Levitated Dipole Experiment (LDX). The self-consistent evolution of an inward particle pinch and the establishment of centrally peaked plasma profiles in a dipole field are explored from whole-plasma simulations using ...

Mesoatomic processes in a pinch plasma
Soviet Atomic Energy, 1990where ~pl is the lifetime of a plasma consisting of deuterium and containing cold (T ~ 1 eV) drops o~ a D-T mixture [i] with tritium concentration C T ~ 0.2 [7, 8]; w M, R, and N M are the fraction of the matter in the form of drops, the radius of the drops, and the density of nuclei in the drops, respectively. When the conditions (i) are satisfied the

Plasma Spectroscopy in Pinch Plasmas
2011Magnetic fields play a very important role in the dynamics of plasmas. Through interactions with the ions and electrons within plasmas, their behaviour and evolution can be drastically influenced. It is the Zeeman effect that is responsible for the splitting of radiative lines observed.
