Diamond Anvil Cell (image) European Synchrotron Radiation Facility Caption This illustration depicts a diamond anvil cell which allows to compress microscopic pieces of material to pressures of 3 Mbar and more. Laser pulses (black arrows) then heat the sample and an X-ray beam (orange) passes through the cell to probe the states of matter at these extreme conditions.
