X-ray spectroscopy

Conference:

Abstract

This paper focuses on high resolution X-ray spectroscopy with particular emphasis on plasma properties diagnostics applications. A basic discussion is made of atomic physics aspects underlying the excitation of the spectral lines, starting with the simplest mechanisms and gradually increasing the complexity of the analysis. At each step in the discussion, an analysis is made of the information that can be obtained on plasma, and recent results produced in experiments with tokamaks are presented. The analysis is devoted to: H-like and He-like ions in low density plasma, whose emission spectra is shown and discussed; the instrumentation used on tokamaks for X-ray spectroscopy; the measurement of ion temperature from line shape; the relevance of line intensity ratios; the process of electron impact excitation and the diagnostic capabilities of dielectronic satellite and inner-shell excitation lines; the relative intensity ratio of the two components of the Lyman-alpha doublet; and the excitation of dielectronic satellites in non-thermal plasmas.
