R. M. Magee and colleagues report the first measurements of proton-boron fusion in a magnetically confined plasma, a reaction that is attractive for energy but technically hard. The fuels are abundant, non-toxic and non-radioactive, and the reaction makes no neutrons, only helium. In the Large Helical Device, boron powder injected at the plasma edge accumulated in the core. Three 2 MW, 160 kV hydrogen neutral beams supplied well-confined, high-energy protons to react with it. A custom detector counted the MeV alpha particles, giving a fusion rate in very good relative agreement with calculations.
