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.

Monetary Award
Varies (~ $300)
The Nuclear Criticality Safety Division’s Technical Excellence Award recognizes individuals for outstanding contributions in the development and application of nuclear criticality safety (NCS) technology. These contributions include, but are not limited to:
The award consists of an engraved plaque and monetary award as the NCSD budget allows (-$300), and is presented at the NCSD Awards Banquet at the ANS Winter Conference.
Anyone can nominate a deserving NCSD member. The nominee must be a member of NCSD. Individuals who were nominated in the past and were not selected may be re-nominated.
The Nuclear Criticality Safety Division established this award in 2000.
The NCSD Honors & Awards Committee solicits nominations from NCSD members. The NCSD H&A Committee will confirm the qualifications of nominees and select the awardees by consensus.
Nominations must include the completed nomination form accompanied by the following supporting documents:
