Inorganic scintillation screens are a common transverse profile diagnostics tool for beams extracted from the heavy ion synchrotron SIS18 at GSI. Detailed investigations concerning light output, profile reproduction and spectral emission were performed for phosphor screens P43 and P46, single crystal YAG:Ce, alumina ceramics and Chromium-doped alumina (Chromox). The screens were irradiated with several ion species from proton to Uranium. The particle energy was 300 MeV/u at intensities in the range from some 10⁶ to 10¹⁰ particles per pulse, using either fast extraction (1μsecond duration) or slow extraction (some 100 ms duration). The light output coincides for both extraction types, i.e. no significant saturation was observed. For all materials the optical emission spectrum is independent on the ion species or beam intensities. Radiation hardness tests were performed with up to 10¹² accumulated ions: The phosphor P46 as well as YAG:Ce shows no significant decrease of light output, while for P43 and Chromox a decrease by 5 to 15 % was measured. These results will trigger the choice of the standard screens installed at the FAIR facility.
