Diamond-anvil cell (IMAGE) Kumamoto University Caption A metal sample is placed inside a rhenium gasket with thermal insulators, squeezed between two diamonds to generate high pressure, and heated with a near-infrared laser. Density measurements under such high-pressure and high-temperature conditions are made by irradiating the sample with x-ray beams.
