Generation of fast neutrons through deuteron acceleration at the PALS laser facility
Result description
Recent experiments at the laser facility PALS focused on the laser driven fusion of deuterons are reviewed. They benefit of high reaction cross-sections and of a high number of multi-MeV deuterons from thick CD2 targets irradiated by intensity of 3x10(16) W cm(2). In the reported experiments fast fusion neutrons with energy up to 16 MeV were produced through Li-7(d, n)Be-8 and B-11(d, n)C-12 reactions in a pitcher-catcher target configuration. When using a large area CD2 foil as a secondary catcher target the total maximum neutron yield from the H-2(d, n)He-3 reaction increased by a factor of about 5, from 4x10(8) to 2x10(9). This result reveals that most of the deuterons having enough kinetic energy to enter a fusion reaction are emitted from the primary target into vacuum.
