Large area imaging of hydrogenous materials using fast neutrons from a DD fusion generator

A small-laboratory fast-neutron generator and a large area detector were used to image hydrogen-bearing materials. The overall image resolution of 2.5mm was determined by a knife-edge measurement. Contact images of objects were obtained in 5–50min exposures by placing them close to a plastic scintil...

Description
Summary:	A small-laboratory fast-neutron generator and a large area detector were used to image hydrogen-bearing materials. The overall image resolution of 2.5mm was determined by a knife-edge measurement. Contact images of objects were obtained in 5–50min exposures by placing them close to a plastic scintillator at distances of 1.5 to 3.2m from the neutron source. The generator produces 109n/s from the DD fusion reaction at a small target. The combination of the DD-fusion generator and electronic camera permits both small laboratory and field-portable imaging of hydrogen-rich materials embedded in high density materials.
