We have developed a compact accelerator-driven neutron facility “AISTANS” at AIST Tsukuba in Japan. This facility is composed of an electron linear accelerator, neutron production source, and neutron beam line. The whole system is optimized for Bragg edge transmission imaging. In this paper, the advantages of neutron spectroscopy, in particular Bragg edge transmission imaging, the basis of the neutron production at AISTANS, and preliminary data are presented.
