Atomic spectroscopy with surface wave plasmas
Analytical and Bioanalytical Chemistry, 1996The 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
1988The 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, 1990Abstract 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.

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.

Spectroscopy of Astrophysical Plasmas
1987A 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.

Reflection Spectroscopy by Plasma-Resonance Enhancement
Applied Optics, 1973By 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 ...

Plasma spectroscopy for magnetically confined fusion plasma
AIP Conference Proceedings, 2007An emission line of neutral helium λ667.8 nm (21P‐31D) is observed with a set of line of sights which covers an entire poloidal cross section of LHD, a heliotron‐type fusion experimental device. From the observed Zeeman splittings and the well‐known magnetic field structure in the plasma, the emission locations on the line of sight are precisely ...

Imaging Spectroscopy at the Plasma–Liquid Interface
Applied SpectroscopyThis contribution presents a novel, simple and cost-effective method for observing the movement of reaction products out of the plasma–liquid interface (PLI). By employing an imaging spectrograph, a multidimensional view, i.e., spatial, spectral, and temporal, of reactions occurring at the PLI is made possible, including the ability to track the ...

Principles of Plasma Spectroscopy
1997This monograph presents a comprehensive description of the theoretical foundations and experimental applications of spectroscopic methods in plasma physics research. The first three chapters introduce the classical and quantum theory of radiation, with detailed descriptions of line strengths and high density effects.
