Public Release: 15-Jun-2017 US-China collaboration makes excellent start in optimizing lithium to control plasma
For fusion to generate substantial energy, the ultra-hot plasma that fuels fusion reactions must remain stable and kept from cooling. Researchers have recently shown lithium, a soft, silver-white metal, to be effective in both respects during path-setting US-Chinese experiments on the Experimental Advanced Superconducting Tokamak (EAST) in Hefei, China.

Physical Review Letters Scientists perform first-principles simulation of transition of plasma edge to H-mode
PPPL physicists have simulated the spontaneous transition of turbulence at the edge of a fusion plasma to the high-confinement mode that sustains fusion reactions. The research was achieved with the extreme-scale plasma turbulence code XGC developed at PPPL in collaboration with a nationwide team.

Physics of Plasmas New model of plasma stability could help researchers predict and avoid disruptions
PPPL physicists have helped develop a new computer model of plasma stability in doughnut-shaped fusion machines known as tokamaks. The new model incorporates recent findings gathered from related research efforts and simplifies the physics involved so computers can process the program more quickly. The model could help scientists predict when a plasma might become unstable and then avoid the underlying conditions.

Physics of Plasmas PPPL physicist uncovers clues to mechanism behind magnetic reconnection
Physicist Fatima Ebrahimi has published a paper showing that magnetic reconnection -- the process in which magnetic field lines snap together and release energy -- can be triggered by motion in nearby magnetic fields.
