Researchers at the University of Rochester, Lawrence Livermore National Laboratory, and France's Centre National de la Recherche Scientifique have developed a method to enhance the accuracy of computer models in simulations of laser-driven implosions.

In laser-driven inertial confinement fusion experiments, intense pulses of light deliver energy to heat and compress a target of hydrogen fuel cells.

The team demonstrated how laser beams modify the conditions of the underlying plasma, which affects the transfer of energy in fusion experiments.

This research validates a longstanding theory, and shows that laser-plasma interaction strongly modifies the transfer of energy.

Said Rochester's Michael Campbell, "The results are a great demonstration of the innovation at the Laboratory and the importance of building a solid understanding of laser-plasma instabilities for the national fusion program."
