Diamond Anvil Cell at ALS Beamline 12.2.2

Caption

At Calipso, the California High-Pressure Science Observatory at beamline 12.2.2 of the Advanced Light Source, materials can be squeezed to tremendous pressures in diamond anvil cells, where they are trapped between the two diamonds in a small central chamber. The X-rays from the beamline pass through the diamonds and the sample, throwing diffraction patterns on a CCD detector that reveal the material’s structure. (Signals from diamond and corundum in the anvil cell mechanism must be subtracted from the diffraction patterns.)
