More than 210 million core hours on two of the most powerful supercomputers in the nation have been won by two teams led by researchers at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory. The highly competitive awards from the DOE Office of Science’s INCITE program will accelerate the development of nuclear fusion as a clean and abundant source of energy for generating electricity and will advance understanding of the high-energy-density plasmas found in stars and other astrophysical objects.
