A multi-MeV alpha particle source via proton-boron fusion driven by a 10-GW tabletop laser
Original language description
Nuclear fusion between protons and boron-11 nuclei has undergone a revival of interest thanks to the rapid progress in pulsed las. technology.Potential appl. of such reaction range from control. nuclear fusion to radiobiology.A laser-driven fusion approach consists in the interaction of high-power,high-intensity pulses with H- and B-rich targets.We report on an experiment exploiting proton-boron fusion in CN-BN targets to obtain high-energy alpha particle beams(up to 5 MeV)using a very compact approach and a tabletop las. system with a peak power of ~10GW,which can operate at high-repetition rate(up to 1 kHz).The secondary resonance in the cross section of proton-boron fusion(~150 keV in the center-of-mass frame)is exploited using a laser-based approach.The generated alpha particles are characterized in terms of energy,flux,and angular distribution using solid-state nuclear-track detectors,demonstrating a flux of ~105 particles per second at 10Hz,and ~106 per second at 1kHz.
