The High Energy Density Sciences group at SLAC National Accelerator Laboratory studies materials in extreme conditions such as very high temperatures and pressures. We use shock waves produced by the Linac Coherent Light Source to compress polycrystalline diamond samples. Compressing these samples allows us to use x-ray diffraction to study...
Mineral inclusions in diamond, brought to the surface through kimberlitic eruptions, provide a unique glimpse into the geochemical inner workings of Earth’s deep interior. Diamonds source a wide range of depths in the mantle. While most diamonds originate from the upper 200 km of the Earth’s mantle, aptly called super-deep...
