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
Observation of faster-than-diffusion magnetic field penetration into a plasma
TL;DR: In this paper, the authors used spectroscopic measurements of the magnetic field, electron density, and turbulent electric fields to study the interaction between a pulsed magnetic field and a plasma.
Journal ArticleDOI
Spectroscopic investigations of a dielectric-surface-discharge plasma source
TL;DR: In this article, the properties of a flashboard plasma source are investigated using spectral line intensities and line profiles, and detailed collisional-radiative modeling is used to analyze the observed line intensity.
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.

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.
