Abstract. This paper presents and discusses an approach to fast-neutron imaging that will provide high-resolution detection (i.e. 1 mm) of small features such as inclusions, voids, and variations in density. The application for fast-neutron imaging centers around assessing low-Z materials in high-Z shielded configurations. For this paper we present a simple theoretical argument on the feasibility of fast-neutron imaging and present results from some of our feasibility measurements. Finally, we discuss the requirements and objectives for the fast-neutron imaging system currently under construction at Lawrence Livermore National Laboratory (LLNL).
