What these terms mean
Every classification on this page, defined. These are controlled-vocabulary terms, so the same word means the same thing on every profile.
- Operator
- Runs a facility, which may have been built by someone else.
- Supplier
- Supplies components, materials or fuel to the sector without developing a reactor or device of its own.
- Fusion
- Organizations pursuing energy from nuclear fusion, and their dedicated supply chain.
- Tokamak › › Tokamak
- Doughnut-shaped magnetic confinement using a strong toroidal field plus a current driven through the plasma itself. The most-studied configuration, and the one ITER uses.
In General Atomics’s own words
Quoted from the organisation’s own site as we archived it. Their description of themselves, not ours, and not a claim this site has checked.
Learn about DIII-D as a User Facility of the U.S. Department of Energy, and our role in the worldwide effort to develop fusion energy.
Where General Atomics sits
Composed from records in this dataset, not from outside research. Every figure below is counted from what the site holds, so it moves when the data does.
General Atomics is one of 10 organisations in this dataset pursuing tokamak.
It is one of 103 we hold in US.
It operates 1 device in this dataset, none of which carries recorded performance figures.

Measured results
Results recorded on this operator’s devices. Design parameters — bore, field, dimensions — are excluded: a machine’s size is not something it achieved. 3 design parameters are held on the device pages.

A source marked operator is the subject’s own publication. That is legitimate, and it is not independent confirmation. Methodology.
