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.

PSA call for journal papers
PSA 2025 has partnered with the ANS journal Nuclear Science and Engineering (NSE) to publish a special issue of papers derived from the conference. Additionally, should you choose not to pursue journal publication, we invite you to consider submitting to the ANS online platform Nuclear Science and Technology Open Research (NSTOR). See below or click here for more information on NSTOR.
If interested, please contact the guest editors listed below or submit directly via the links below.
**Submission window: open now with a final deadline of September 30, 2025

Submittal instructions:
Please consider the scopes of the journals when deciding where to submit.
Nuclear Science and Engineering welcomes submissions that explore basic and fundamental research in all areas related to nuclear science and engineering.Submit to NSE – Questions? Email nse@ans.org.
Nuclear Science and Technology Open Research welcomes submissions where authors prefer, or funders require, a fully open publication venue for research articles, and/or where authors would like to submit article types not typically supported by archival journals (e.g., brief reports, method articles, data notes, posters/presentations).Submit to NSTOR – Questions? Email nstor@ans.org
Thank you again for attending PSA 2025, and we hope you participate in this special issue opportunity!
Our very best,
