Copper melting behavior at extreme temperatures could inform fusion materials
Using SLAC’s electron camera, researchers recorded timestamps of solid copper atoms (orange) as they melted (yellow) after being blasted with laser heat. This graphic shows how copper atoms changed over a period of several femtoseconds (millionths of a billionth of a second), notated here as fractions of a picosecond. Instead of the predicted collapse, the researchers saw a gradual melting. (Image: Greg Stewart/SLAC National Accelerator Laboratory)
The SLAC National Accelerator Laboratory has announced researchers have conducted experiments testing how copper melts under extreme conditions, such as those it might be exposed to in a fusion machine. The results, published in Nature Communications, found that a copper thin film was more resilient to melting than models had predicted, uncovering molecular dynamics that had been missing from calculations.
“These results greatly improve the simulations we use to predict which materials have the best shot at surviving the extreme conditions of future fusion reaction chambers,” said Mianzhen Mo, the SLAC staff scientist who led the research.

A number of research reactors, test reactors, and facilities are in operation or are being developed and built. They support important R&D programs towards current and future developments. Many of these facilities are at university campuses, serving as both educational and R&D instruments. Although the design space of research facilities is dominated by light water systems, interest is growing in expanding research capabilities towards advanced research reactors. Universities are exploring pathways to bring either advanced research reactors or advanced irradiation capabilities to their campuses. Recently, Abilene Christian University received a construction permit approval to bring Natura Resources MSR-1 as the university advanced research reactor. This panel, composed of university community experts, will discuss ongoing and planned efforts involving research reactors, test reactors, and research facilities focusing on the significant opportunities offered by these systems in support of advanced reactor R&D. Economics, deployment, and licensing related to having such facilities on university campuses will be taken into discussion.
