<title>Discovering New Talents for Diamond</title>

<pubDate>February 25, 2010</pubDate>

<description><![CDATA[Researchers using an x-ray beamline at the U.S. Department of Energy&#39;s Advanced Photon Source at Argonne have discovered that synthetic diamond crystals exhibit a very high degree of perfection. This makes them indispensable for the realization of next-generation, fully coherent hard x-ray sources such as x-ray free-electron laser oscillators that have the potential for unprecedented average brightness along with record narrow spectral bandwidths.]]></description>
