Peering into 36-million-degree plasma with SLAC’s X-ray laser
SLAC National Accelerator Laboratorya team of researchers has used an X-ray laser to measure, for the first time, how a plasma created by a laser blast expands in the hundreds of femtoseconds (quadrillionths of a second) after it’s created. Their technique could eventually reveal tiny instabilities in the plasma that swirl like cream in a cup of coffee.
