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.

National laboratory
A state-funded laboratory operating at national scale, usually running facilities no single university could support.
Operator
Runs a facility, which may have been built by someone else.
Fusion
Organizations pursuing energy from nuclear fusion, and their dedicated supply chain.

Where Princeton Plasma Physics Laboratory 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.

It is one of 103 we hold in US.

It operates 2 devices 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.
