Journal ArticleDOI
Ion separation due to magnetic field penetration into a multispecies plasma.
TL;DR: It is found that ion separation occurs in which a light-ion plasma is pushed ahead while a heavy- ion plasma lags behind the magnetic piston, and most of the momentum imparted by the magnetic field pressure is taken by the reflected light ions.
Journal ArticleDOI
Observations of two-dimensional magnetic field evolution in a plasma opening switch
TL;DR: In this paper, the time dependent magnetic field distribution was studied in a coaxial 100ns positive-polarity plasma opening switch (POS) by observing the Zeeman effect in ionic line emission.
Journal ArticleDOI
Spectroscopic investigation of fast (ns) magnetic field penetration in a plasma
TL;DR: In this article, the time-dependent magnetic field spatial distribution in a coaxial positive-polarity plasma opening switch (POS) carrying a current ≂135 kA during ≂100 ns, was investigated by two methods.
Journal ArticleDOI
Spectroscopic investigations of the plasma behavior in a plasma opening switch experiment

TL;DR: In this article, the electron density, the electron kinetic energy, the particle motion, and electric fields in a coaxial positive-polarity plasma opening switch (POS) were studied using spectroscopic diagnostics.
Journal ArticleDOI

TL;DR: In this paper, the authors investigate the interaction of fast-rising magnetic fields with multi-species plasmas at densities of 1013-1015 cm−3 and find that the magnetic field propagation velocity is faster than expected from diffusion.
