Copper defies the fusion superheating limit in material test
TL;DR
Researchers at SLAC used the MeV-UED electron camera to image copper as it was heated with laser pulses, revealing a gradual melt and maintained lattice order past the predicted superheating limit under dynamic pressure — a result that upends older models and improves fusion-material simulations.
