Within the research group CLEAR we endeavor to understand large scale geological processes that operate deep inside planets. Our approach is to recreate high pressure-temperature conditions in the laboratory and examine various physical properties of minerals and rocks (in situ) using state-of-the-art spectroscopic techniques. Specifically, we use statically- and dynamically-heated diamond anvil cells together with a pulsed time-resolved broadband optical probe and a precisely-synchronized …

For quantitative interpretation of impact ionization spectra, analogue experiments in the lab are mandatory. For mineral and organic dust particles, this is achieved by electrostatic acceleration of micron and sub-micron sized dust grains of known composition that are fired upon duplicates of the space detectors.
Acceleration of icy particles to the desired speed is currently not possible. However, to simulate icy particle impact one can use a laser-driven analogue setup. Here a highly …
