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.
Laser ICF, indirect drive › › Laser ICF, indirect drive
Laser energy converted to X-rays in a hohlraum, which drives the capsule. The NIF configuration.
Deuterium–tritium
Lowest ignition threshold; 80% of energy in 14.1 MeV neutrons. The reference fuel for every near-term net-gain claim.

In Lawrence Livermore National Laboratory’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.

LLNL’s National Ignition Facility is the only lab on Earth to achieve fusion ignition. Since making history in 2022, each repeat deepens our understanding of high energy density and fusion science. Explore how NIF brings star power to Earth in service of U.S. national security.

The Department of Energy and National Nuclear Security Administration have approved a path forward for a project that will increase the laser energy available to NIF at LLNL. The Enhanced Yield Capability project will enable more pertinent assessments and modernization efforts for the nation’s nuclear stockpile.

Where Lawrence Livermore National 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.

Lawrence Livermore National Laboratory is one of 3 organisations in this dataset pursuing laser icf, indirect drive.

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. 1 design parameter are held on the device pages.
