Title Energetic neutron beams generated from femtosecond laser plasma interactions
Contributors
Abstract Experiments at the HERCULES laser facility have produced directional neutron beams with energies up to 16.8(±0.3) MeV using d12(d,n)32He,Li73(p,n)74Be,andLi37(d,n)84Be reactions. Efficient Li12(d,n)84Be reactions required the selective acceleration of deuterons through the introduction of a deuterated plastic or cryogenically frozen D2O layer on the surface of a thin film target. The measured neutron yield was ≤1.0 (±0.5)×107 neutrons/sr with a flux 6.2(±3.7) times higher in the forward direction than at 90∘. This demonstrates that femtosecond lasers are capable of providing a time averaged neutron flux equivalent to commercial d12(d,n)32He generators with the advantage of a directional beam with picosecond bunch duration.
