X-ray Spectroscopy of Highly Charged Ions - Diagnostics
Energy-dispersive X-ray Spectrometry
The X-ray spectra are measured with an energy-dispersive Si(Li) detector (FWHM=133 eV at 5.9 keV). Their structure, that is the transition energies and their intensities account for the produced ion species and their charge state distribution.
The transition lines above the electron beam energy are due to radiative recombination in open shells of the ions which even can detect bare ions.

Wavelength-dispersive X-ray Spectrometry
Measuring X-ray spectra with a crystal diffraction spectrometer is rather complex and time-consuming but results in a high resolution which allows to account for specific transition lines separately.
