US fusion research at 180,000°F super-hot plasma reveals unexpected heat flow barrier

SMRTR summary

Researchers discovered an unexpected heat flow barrier in super-hot plasma at 180,000°F using the Omega-60 laser. Heat struggled to move between different materials in high-energy-density plasma, challenging assumptions about heat behavior in extreme environments like stars and fusion experiments. This finding has implications for inertial confinement fusion research and technologies involving hypersonic flight and semiconductor etching.
