Beamed neutron emission driven by laser accelerated light ions

Abstract:

Highly anisotropic, beam-like neutron emission with peak flux of the order of 109 n/sr was obtained from light nuclei reactions in a pitcher–catcher scenario, by employing MeV ions driven by a sub-petawatt laser. The spatial profile of the neutron beam, fully captured for the first time by employing a CR39 nuclear track detector, shows a FWHM divergence angle of $\sim 70^\circ $, with a peak flux nearly an order of magnitude higher than the isotropic component elsewhere. The observed beamed f...
