However, some tokamaks, including the DIII-D tokamak in San Diego, have now experimented with the inverse shape known as negative triangularity.

Two seconds of hope for fusion power A fusion reactor in San Diego surpasses a limit on plasma density.

ITER engineers expect their tokamak reactor to generate 500 megawatts (Mw) of fusion power using just 50 Mw of input heating–compared with a nuclear fission reactor ’s roughly 1,000 Mw of ...

While the modeling framework looked at DIII-D, a tokamak operated by General Atomics in San Diego, the next phase of this research involves scaling the modeling framework to ITER.

DIII-D, pronounced “dee-three-dee,” is the largest tokamak in the United States. General Atomics’ fusion pilot plant will require building a brand new tokamak, among other infrastructure.

Westinghouse Electric has secured a $180m contract from ITER for the assembly of a nuclear fusion reactor’s vacuum vessel in ...

Almost unlimited clean energy has been brought a step closer with the setting of a new world record for the sustained running of a nuclear fusion reactor. China's "artificial sun"—formally known ...

San Diego’s General Atomics passes a milestone. Can nuclear fusion energy become a reality? The DIII-D facility is a cornerstone of research seeking to develop a virtually limitless, carbon-free ...

The DIII-D tokamak is a device designed not to produce energy, but to help researchers study the physics of the plasma where energy-releasing fusion reactors would take place and develop the ...

Physics Nuclear fusion experiment overcomes two key operating hurdles Two important barriers to a stable, powerful fusion reaction have been leapt by an experiment in a small tokamak reactor, but ...

The testing occurred at the Department of Energy's DIII-D National Fusion Facility in San Diego (see above). This tokamak reactor has been operating since the 1980s, and like all current fusion ...
