Conceptual design of a novel high-frame-rate fast-neutron radiography facility

Neutron radiography is a well-established technique. However, fast-neutron radiography is relatively new and unexplored, although several advantages are manifest. Here, a description is given of a concept of a high-frame-rate fast-neutron radiography instrument. Specific advantages for the instrument considered here are: - A high frame rate realised by the use of an intense pulsed neutron source created by an accelerator facilitating the investigation of dynamic processes. - Neutron-energy selection by means of time-of-flight facilitating resonance energy contrast variation. - Optional horizontal or vertical illumination of a sample by means of an adjustable neutron source position. - Stereoscopy realised by two neutron source positions.Typical features and design considerations are discussed. The possibility is shown that these different techniques are combined in one optimally designed high-frame-rate fast-neutron radiography instrument
