Proponents of inertial fusion energy celebrated in December 2022, when researchers at the National Ignition Facility at Lawrence Livermore National Laboratory achieved fusion ignition by subjecting a carefully crafted diamond cryogenic sphere containing frozen deuterium-tritium fuel to NIF’s laser energy. NIF has yet to repeat the feat, in part because that facility was not designed to produce fusion energy, and ignition requires near-perfect targets. For inertial fusion energy to serve as a reliable power source, it will require swift, reliable, and economic target production.
