A deuteron is the atomic nucleus of a type of heavy hydrogen called deuterium, and consists of a proton and a neutron. Phoenix’s neutron generators fire deuterons into chambers full of tritium, an even heavier form of hydrogen that has a proton and two neutrons as its nucleus. A high-speed collision between a deuteron and a tritium nucleus causes the two to fuse, creating helium and spitting out a neutron.
Evan Sengbusch, Phoenix’s president, says the company is supplying eight accelerators for a new isotope factory to be run by’s boss, Greg Piefer, says the facility will be finished in 2021, with the first production shortly thereafter. By 2023, he hopes,
