The chemical element lithium may just have found itself a new application. Scientists at the Princeton Plasma Physics Laboratory (PPPL) and China's Experimental Advanced Superconducting Tokamak (EAST) have found that lithium powder can reduce periodic instabilities in plasma when used to coat tungsten surfaces in fusion devices.

These instabilities are known as edge-localized modes (ELMs) and occur at the outer parts of the fusion plasma. ELMs develop regularly when the plasma enters what is known as high-confinement mode, or H-mode, which holds heat within the plasma more efficiently. ELMs can damage the divertor, a plasma-facing component that extracts heat and ash produced by the fusion reaction, and cause fusion reactions to fizzle.

The researchers also found that it became easier to eliminate ELMs as the experiments progressed, possibly requiring less lithium as time went on.

The results cause physicists to be confident that these techniques could also reduce ELMs in larger fusion devices that were designed to be compatible with lithium.

February at ITER opened with a high-stakes visit from the Committee on A Strategic Plan for U.S. Burning Plasma Research. The Committee, operating under the auspices of the US National Academies of Sciences, Engineering, and Medicine, has been charged with reviewing the overall state of magnetic confinement fusion research in the United States. A key outcome of the review is to be a recommended strategy for going forward—with or without ITER—in a way that preserves the US status as a leader in burning plasma research.

The Committee publicly released its interim report on 21 December 2017.
