“…After that, in the third section, we will use those data in the PCM to predict the changes in the spectral lines' form and position. In the fourth section, we will use real-beam parameters along the PCM (RBPCM) based on a numerical method developed in [16]. The paper will be concluded with the summary and conclusions section.…”

In this paper, we propose to use quasi-monochromatic Cherenkov spectral lines for ion beam diagnostics. As representatives of light and heavy ions, we use C12 and Au197 ions, respectively. First, using the Geant4 toolkit, we determine the ionization lost energy as a function of the radiator penetration depth. After that, we use those data in the polarization currents method to compare the theoretical spectral lines with and without ionization losses. We also use the real-beam polarization currents method to analyze real-beam and setup parameters affecting the accuracy of the beam diagnostics. We emphasize that the precision of refractive index measurement might be a source of inaccuracy in ion beam diagnostics. Nevertheless, according to the provided data, we can expect that the method for measuring Cherenkov quasi-monochromatic spectral lines should be applicable for beam-diagnostics purposes, especially for lighter ions.
