Synchrotron (IMAGE) Arizona State University Caption To measure crystal structures at the atomic scale at high pressure and temperature, a diamond-anvil cell with a sample is aligned with an X-ray beam (blue line) and laser beams (orange areas). The laser beams heat the sample to thousands of kelvins in temperature. The small red/gray rectangle sandwiched between diamond anvils is the sample.
