CASE STUDY: Goodfellow Materials Power Historic Fusion Ignition Breakthrough at LLNL
On December 5, 2022, the Lawrence Livermore National Laboratory (LLNL) in California achieved a monumental milestone: fusion ignition at the National Ignition Facility (NIF). This historic demonstration marked the first time a laboratory experiment produced more energy from a fusion reaction than the energy used to initiate it: a condition known as ignition.
Goodfellow Ltd. is proud to have provided critical, specialized materials that contributed to this groundbreaking achievement, helping to overcome one of the major barriers to producing clean energy.
The NIF experiment involved firing the facility’s 192 powerful lasers onto a BB-sized target of deuterium and tritium (DT), heavier isotopes of hydrogen. By delivering 2.05 megajoules (MJ) of laser energy, LLNL scientists achieved a fusion energy output of 3.15 MJ, demonstrating a net energy gain. This peer-reviewed and externally verified result confirms the fundamental principles of inertial confinement fusion (ICF), marking a transformative breakthrough for fusion energy and a critical step toward the pursuit of limitless, clean power.
“Simply put, this is one of the most impressive scientific feats of the 21st century.” (U.S. Secretary of Energy Jennifer M. Granholm)
“This is the breakthrough everybody has been waiting for, and it is exciting to have played a small, but critical part in supporting them on their journey to this discovery.” (Dr. Aphrodite Tomou, Goodfellow’s Head of Technical)
The LLNL historic experiment achieved the first instance of scientific breakeven controlled fusion, with an energy gain factor of 1.5.
