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 …

The hydrothermal diamond-anvil cell (HDAC) can be applied to study fluids, solids and particularly aqueous samples in situ at high pressures and temperatures. Although such cells are usually used at P-T conditions of less than 3 GPa and 850 °C, experiments with aqueous fluids to 23 GPa and 1025 °C have been reported in the literature.
Because diamonds are transparent over a large range of the electromagnetic spectrum, samples in the HDAC can in principle be studied using any "photon-in – …
