Efficient Neutron Generation with Sub-J Short Pulse Lasers

抄録

We present results from experimental investigations to generate a high flux source of energetic neutrons using a short pulse high rep rate laser system. Interactions of the laser pulse with a heavy water stream target allowed the generation of ~105 neutrons/second at an energy of ~2.45 MeV. We used liquid scintillators with pulse shape analysis along with bubble detectors to confirm neutron production. Further optimization of the target as well as an increase in the rep rate of such laser systems has the potential to enable the development of a high flux laser driven portable neutron source.
