Neutral particles a drag on disruptive plasma blobs

For decades, scientists have been working to harness clean, renewable fusion energy, which occurs naturally in stars like our sun. Using strong magnetic fields to confine hot plasmas within a donut-shaped device called a ...

Unveiling the steady progress toward fusion energy gain

The march towards fusion energy gain, required for commercial fusion energy, is not always visible. Progress occurs in fits and starts through experiments in national laboratories, universities, and more recently at private ...

Integrating hot cores and cool edges in fusion reactors

Future fusion reactors have a conundrum: maintain a plasma core that is hotter than the surface of the sun without melting the walls that contain the plasma. Fusion scientists refer to this challenge as "core-edge integration." ...

Harnessing hot helium ash to drive rotation in fusion reactors

In controlled nuclear fusion, heavy isotopes of hydrogen fuse into helium, releasing a huge amount of energy in the process. A large portion of the energy released by a laboratory fusion reaction goes into hot helium ash ...

Visualizing the microscopic world of fast ions in fusion devices

The U.S. scientific community is currently conceptualizing the first nuclear fusion power plants, which will revolutionize energy production. Like the sun and stars, a fusion power plant will produce energy by fusing light ...

Micro-scale current sheets unleash macro-scale space weather

While movies show Earth as existing in a calm, pristine corner of the universe, in reality the near-Earth space environment is dangerous and dynamic. On any given day, hot charged particles and blobs of plasma, called the ...

Calling all 'fusioneers'! New US fusion energy website launches

The U.S. Fusion Outreach Team, a grassroots organization in the fusion community focused on reducing barriers to outreach efforts, has launched a new centralized website to engage an expanding workforce, media, educators, ...
