Measurements of Potential Positive Ion Sources of Gadolinium

The work describes measurements of potential sources of gadolinium (Gd) ions. The measurement methods and preliminary results are presented. The aim of this research is to develop a positive Gd ion source for further experiments, particularly the measurements of negative ions. Two methods were used for creating Gd atom and ion emission spectral lines: laser-induced breakdown spectroscopy (LIBS) and hollow cathode (HC) discharge combined with radiofrequency inductively coupled plasma (ICP). For this research, samples of gadolinium oxide Gd2O3 and gadolinium Gd were used in HC-ICP device, and Gd2O3 samples for LIBS. The recorded plasma spectra was analyzed to identify atomic and ion emission lines.
