Laser Driven Neutron Generation at the Texas Petawatt
ORAL
Abstract
We realized a bright laser-driven neutron source at the Texas Petawatt laser facility. We investigated the interplay between ion- and x-ray- driven neutron production regimes, by scanning a large range of target thicknesses, converter materials and laser parameters. We employed a large suite of electron, ion, gamma and neutron diagnostics to obtain a complete characterization of the interaction energetics. Neutron yields in excess of 10$^{9}$ neutrons/shot with a fairly isotropic distribution were measured.
