"Condensed matter research on large-scale devices", Project „High temperature kinetics experiments for the investigation of material syntheses with photoionization mass spectrometry (KEIM)“

The aim of the project was to investigate the gas phase and the formation of growth species and small particles in high-temperature syntheses of condensed materials in situ. For this purpose, a novel mass spectrometer system optimized for particle detection was set up, consisting of an ion trap, an ion mobility spectrometer and a time-of-flight mass spectrometer, which can use narrow-band VUV radiation for selective photoionization. This extraordinary combination of methods makes it possible to determine the composition and form of intermediates and also to distinguish isomers in order to identify important growth species and understand the chemical processes involved in synthesis.
