Nuclear technology companies Phoenix and SHINE Medical Technologies have achieved a new world record for a nuclear fusion reaction in a steady-state system, the strongest of its kind ever produced on Earth. The reaction yielded 46 trillion (4.6×1013) neutrons per second, eclipsing the previous record by nearly 25% and setting a new standard for neutron generator technology.

The Phoenix system works by accelerating positively-charged deuterium ions into a target of tritium gas to induce a fusion reaction. This reaction results in the production of high-energy neutrons and helium. These neutrons then pass into a tank and strike their target: low-enriched uranium (LEU) dissolved in an aqueous solution. This causes the uranium nuclei to split and create multiple elements, including Mo-99 and other useful isotopes.

Gas target, eh?
