N2 - A standard method to measure beam profiles is to use scintillating screens. Such technique is used e.g. at the European XFEL in order to overcome coherence effects in case of OTR based diagnostics. However, already during the XFEL commissioning, the standard screen material LYSO:Ce has revealed a new problem - non-proportionality effects. The reason is a high electron bunch density. Therefore it was decided to exchange LYSO:Ce by GAGG:Ce, as the material has not shown any signs of non-proportionality in a series of measurements at the XFEL. Nevertheless, further studies are ongoing. The last measurement campaign has been carried out at PITZ (DESY Zeuthen) which has two important advantages compared to the XFEL: (1) a higher bunch charge and (2) a lower electron energy. Five different scintillating materials have been investigated: LYSO:Ce, YAP:Ce, YAG:Ce, LuAG:Ce and GAGG:Ce. The present work comprises the results of the latest measurements.
