Abstract

The National Ignition Facility at Lawrence Livermore National Laboratory is in need of a gamma-ray imaging diagnostic system to image imploding capsules for inertial confinement fusion experiments. A prototype system was designed and constructed to image 4.44 MeV gammas resulting from 12C(n,n’ γ)12C interactions with the plastic ablator. Testing of the system was undertaken at the OMEGA Laser at the University of Rochester using hard x-rays from an imploding capsule and at the High Intensity Gamma Source at Duke University using a 4.47 MeV gamma beam. The results of these tests produced a number of lessons and recommendations presented here.
