Development of Neutron Visual Sensing Techniques

Abstract

Neutron visual sensing techniques are powerful and attractive advanced techniques for many kinds of scientific and industrial fields. In this article, the followings are described; (1) attractive points, (2) development of neutron visual sensing techniques at JAEA by now, (3) some applications, (4) prospects for future and (5) problems for the spread. The high-speed 2D method, high-speed scanning 3D/4D CT method, and multi-beam 4D CT method which have been developed by JAEA are reported. Visualization of oil flow in a mortaring car engine by the high-speed 2D method and 4D view of the falling sand flow in sand glasses by the high-speed scanning 4D CT method, which are carried out using JRR-3, are shown as application samples. Now, we run toward the development of the advanced pulse neutron visual sensing techniques for the multi-purpose applications using J-PARC as the pulse neutron source.
