The high resolution of a Bragg crystal diffraction spectrometer was us
ed to investigate the ion charge distribution of krypton ions inside t
he plasma of an 14.5 GHz ECR ion source. Analyzing the measured spectr
a, we got information about the abundances and the relative densities
of krypton ions of different charge states.
