SHINE Medical Technologies and Phoenix set a world record for a nuclear fusion reaction in a steady-state system, the strongest of its kind ever produced on Earth, SHINE announced today.

According to a release, the reaction yielded 46 trillion neutrons per second, which beat the previous record, held by the Rotating Target Neutron Source II facility in Livermore, Calif., by nearly 25 percent.

“The world record proves the accelerator technology is suitable to produce medical isotopes at the scale required to support a robust business case,” SHINE CEO Greg Piefer said in a statement.

The world record was set in late July during a demonstration of Phoenix’s third-generation gas-target neutron generator.
