X-ray plasma diagnostics

Results and methods are given for the investigation of hot laboratory and astrophysical plasmas parameters in a soft X-ray region 1 = 1-40 A. Line spectra of multiply charged ions are usually studied exper~mentally, and relative Intensities of spectral lines are measured. Achievements of modern physics of electronion collisions and theoretical spectroscopy make it possible to obtain for transie...

Cold Plasma Chemistry and Diagnostics

This paper gives an overview of the main chemical processes which take place in cold plasmas generated in glow discharges, both in the gas phase and at the surfaces in contact with the plasma. Illustrative examples are provided where the relevance of different processes is evinced. Most common plasma characterization techniques and their recent improvements are also presented briefly.

Use of the Plasma Spectrum RMS Signal for Arc-Welding Diagnostics

A new spectroscopic parameter is used in this paper for on-line arc-welding quality monitoring. Plasma spectroscopy applied to welding diagnostics has typically relied on the estimation of the plasma electronic temperature, as there is a known correlation between this parameter and the quality of the seams. However, the practical use of this parameter gives rise to some uncertainties that could...
