A combination of PPPL modeling led by physicist Gerrit Kramer and DIII - D experiments has found that broadening the electric current in the center of plasma could reduce the loss of crucial elements called alpha particles that heat the plasma and sustain fusion reactions.

Also selected to participate in Cori's NERSC Exascale Science Applications Program (NESAP) is the PPPL - led M3D - CI, an extended magnetohydrodynamics (MHD) code focused on simulation of plasma disruptions led by physicist Stephen Jardin, with support from physicists Joshua Breslau, Nate Ferraro and Jin Chen.

U.S. Department of Energy (DOE) high - performance computer sites have selected a dynamic fusion code, led by physicist C.S. Chang of the DOE's Princeton Plasma Physics Laboratory (PPPL), for optimization on three powerful new supercomputers.

The cause, according to a theory advanced by PPPL physicist David Gates and colleagues at the Laboratory, lies in the tendency of bubble - like islands that form in the plasma that fuels fusion reactions to shed heat and grow exponentially — a runaway growth that disrupts the crucial current that completes the magnetic field that holds the plasma together.

«The trim coils have proven extremely useful, not only by ensuring a balanced plasma exhaust onto the divertor plates, but also as a tool for the physicists to perform magnetic field measurements of unprecedented accuracy,» said Thomas Sunn Pederson, Max Planck director of stellarator edge and divertor physics.
