Abstract
To realize neutron energy resolved three-dimensional (3D) imaging in the resonance neutron energy region, a camera system coupled with a high sensitivity and high frame-rate gating image-intensifier was developed. The resonance absorption 3D imaging was successfully demonstrated at the pulsed neutron source of the Japan Proton Accelerator Research Complex (J-PARC). The camera system allowed us to obtain a time-of-flight (TOF) image of 2352 (W)Ã1726 (H) pixels resolved into a narrow energy range. 3D images with enhanced contrast at corresponding resonance energy regions for cylindrical Au, Ta, and In samples were reconstructed by convolution filtered back-projection (FBP) and maximum likelihood expectation maximization (MLEM) methods. The spatial resolution in the depth direction was evaluated experimentally to be approximately 1Â mm. Our results show that the system could have applications in industrial fields.
