A fusion power plant could generate carbon-free energy at a scale needed to address climate change.
Researchers worldwide are making progress toward meeting that goal.
Key to a fusion reactor is a superheated plasma that's reacting inside a vacuum vessel.
The problem is finding a material for the vacuum vessel that remains strong enough to keep the reacting plasma and coolant apart.
Researchers found a metric that is easy to compute and reliable indicator of helium embedding energy.
The metric is the atomic-scale free volume, the size of the internal vacant space available for helium atoms to settle.
The researchers then implanted helium ions into the sample at a temperature similar to that in a fusion reactor and watched as bubbles of helium formed.
Having confirmed their approach, the researchers searched for helium-absorbing compounds that would work well with iron.
