AWhat changed
The NIF collaboration measured fusion output exceeding laser energy delivered to the target in its December 2022 experiment. LLNL reports that machine-learning-assisted simulation supported pre-shot predictions alongside expert design.
Scientific scope
The NIF collaboration measured fusion output exceeding laser energy delivered to the target in its December 2022 experiment. LLNL reports that machine-learning-assisted simulation supported pre-shot predictions alongside expert design. Scope limitation: Target gain is not net electricity or wall-plug energy breakeven. Human teams designed, built and operated the experiment; CogSim supported prediction, not autonomous discovery. Source byline positions are retained, including repeated initials; these are not verified distinct person identities.
Evidence
Assessment uses the catalogue-linked source evidence for the stated contribution. Target gain is not net electricity or wall-plug energy breakeven. Human teams designed, built and operated the experiment; CogSim supported prediction, not autonomous discovery. Source byline positions are retained, including repeated initials; these are not verified distinct person identities.
