We developed a new dust source. Different dust samples have been accelerated at a test bench. A first data set with the prototype of the source was achieved at the 2 MV accelerator and met our expectations. We can now provide a wider range of projectile materials than before. E.g. the latex particles can simulate micrometeorites that have a low density and consist of organic materials. This will help to calibrate micrometeorite impact detectors and will improve our understanding of their time-of-flight spectra. It can also help to understand the impact physics better.
