Recent status and measurement examples of the compact accelerator-driven neutron facility AISTANS

Abstract

AISTANS, which is optimized for the Bragg-edge imaging, has been utilized for industrial applications. A second beamline was recently constructed and is under preparation for neutron analysis use. The power of the electron beam, which is used for neutron production at a tantalum target, is currently approximately 1 kW and it is planned to be increased. At AISTANS, various sizes of automobile parts have been analysed non-destructively by neutron radiography, computed tomography, and the Bragg-edge method. Recently, other industrial applications such as analysis of lithium-ion batteries using Bragg-edge spectroscopy have been performed. The neutron diffraction method using a newly developed diffractometer is combined for the Bragg-edge analysis.
