High-current stream of energetic alpha particles from laser-driven proton-boron fusion
Original language description
The nuclear reaction known as proton-boron fusion has been triggered by a subnanosecond laser system focused onto a thick boron nitride target at modest laser intensity (∼10to16 W/cm2), resulting in a record yield of generated α particles. The estimated value of α particles emitted per laser pulse is around 10to11, thus orders of magnitude higher than any other experimental result previously reported. The accelerated α particle stream shows unique features in terms of kinetic energy (up to 10 MeV), pulse duration (∼10 ns), and peak current (∼2 A) at 1 m from the source, promising potential applications of such neutronless nuclear fusion reactions. We have used a beam-driven fusion scheme to explain the total number of α particles generated in the nuclear reaction.
