Abstract Scope Recent advances in the design of diamond anvil cells for reaching extremely high pressures and temperatures have been combined with irradiations using swift heavy ions. Relativistic ions provide a unique opportunity to access states of matter far from thermodynamic equilibrium. Each projectile deposits exceptional amounts of energy (GeV) within an exceedingly short interaction time (sub-fs) into nanometer-sized volumes of a material. The coupling of extreme energy deposition with high pressures dramatically alters transformation pathways and can lead to the formation of new states of matter. This experimental approach allows us to form and stabilize novel phases (e.g., GeO2 and Gd2Zr2O7) and to manipulate the properties of solids at the nanoscale (e.g., CO2). A further application is to investigate the effects of radioactive decay in compressed and heated minerals of Earth’s interior, such as fission-track formation under crustal conditions and phase transitions of damaged minerals (e.g., ZrSiO4) resulting from meteorite impact.
