US-China collaboration makes excellent start in optimizing lithium to control plasma

DOE/Princeton Plasma Physics Laboratory
Business Announcement

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.

Physicists discover that lithium oxide on tokamak walls can improve plasma performance

DOE/Princeton Plasma Physics Laboratory
Peer-Reviewed Publication

A team of physicists has discovered that a coating of lithium oxide on the inside of fusion machines known as tokamaks absorbs as much deuterium as pure lithium does.

Scientists perform first-principles simulation of transition of plasma edge to H-mode

DOE/Princeton Plasma Physics Laboratory
Peer-Reviewed Publication

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.
