Plasma Spectroscopy in Pinch Plasmas

2011
Magnetic 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.

Principles of Plasma Spectroscopy

Nuclear Fusion, 1998
This book gives a comprehensive treatment of plasma spectroscopy, the quantitative study of line and continuous radiation from high temperature plasmas. This highly interdisciplinary field combines elements of atomic, plasma and statistical physics, and has wide application to simulations and diagnostics of laboratory and astrophysical plasmas ...

“All air–plasma” terahertz spectroscopy

Optics Letters, 2011
We demonstrate terahertz wave generation and detection capabilities up to 6 THz without the need for solid state materials, biased electrodes, or forward propagating signal collection. An "all air-plasma" terahertz system is used to encode explosive material resonant signatures into the 357 nm nitrogen fluorescence line of a bichromatic field-induced ...

Atomic spectroscopy with surface wave plasmas

Analytical and Bioanalytical Chemistry, 1996
The use of microwave induced plasmas, particularly of surface wave plasmas, as detectors in atomic emission spectrometry for elemental analysis is reviewed. Surface wave plasmas have been produced at low HF power and used as gas chromatographic detectors.

Elementary plasma spectroscopy

1988
The preceding chapters have shown that the widths, shapes and intensities of spectral lines depend on the temperature, pressure and electron density of the environment of the atom or molecule, as well as on its intrinsic properties. If the broadening and other physical processes are properly understood and the necessary atomic parameters are known, the

Simulation microfield method for plasma spectroscopy

Journal of Quantitative Spectroscopy and Radiative Transfer, 1990
Abstract A computer simulation method has been developed to analyze the effect of the ionic microfield fluctuations on the spectral line shape of hydrogenic emitters. The simple simulation model involves use of independent perturbers interacting with the emitter through a Debye potential and is valid for weakly-coupled plasmas.

Reflection Spectroscopy by Plasma-Resonance Enhancement

Applied Optics, 1973
By placing a thin layer of a metal with plasma frequency omega(p) upon a substrate of a second metal with a plasma frequency much greater than omega(p) a configuration is created that greatly enhances plasma-resonance effects upon reflectance. Sample results of calculations for films of potassium and silver deposited upon an aluminum substrate are ...

Spectroscopy of Astrophysical Plasmas

1987
A group of acknowledged experts describe the use of spectroscopy as a diagnostic probe of astronomical environments. The broad sweep of the book enables good coverage to be given to all the situations in which plasmas are encounteres in astronomical investigations.

Basics of plasma spectroscopy

Plasma Sources Science and Technology, 2006
These lecture notes are intended to give an introductory course on plasma spectroscopy. Focusing on emission spectroscopy, the underlying principles of atomic and molecular spectroscopy in low temperature plasmas are explained. This includes choice of the proper equipment and the calibration procedure.
