Development of a short pulse neutron source using the NIF-ARC laser

POSTER

Abstract

Neutron sources are used in a wide variety of applications including material science, isotope production and radiography. Short pulse laser-driven neutrons have unique characteristics such as sub-ns durations and high peak brilliance. The peak flux that is often required to probe temporally evolving environments has not yet been demonstrated for these laser-driven sources. Here, we report on the platform development of a pitcher-catcher neutron source using the large spot size, multi-kJ, multi-picosecond NIF-ARC laser. The initial experiments explored laser energy scaling at ARC conditions and catcher configuration and measured neutron yield, spectrum, and directionality.
