Paper Abstract

Testing of the gamma ray imaging system will continue at the High Intensity Gamma Source (HIGS) at Duke University. Previous testing at OMEGA gave useful information but at much lower photon energies. Utilizing HIGS 108 gammas/s and its tight beam we will be able to characterize the system in the energy regime that it was designed for namely 4.44 MeV. HIGS offers the ability to tune the beam’s energy from 1-20 MeV by way of controlling the inverse Compton scattering off of a relativistic electron beam. With this feature characterization in a range of energies will be possible. Targets were made using a ray-tracing program that replicates a 12-micron ideal pinhole and a 20 cm long 300-micron gold penumbra aperture. The latter will require reconstruction of the coded images.
