As part of the Innovative Structural Materials R&D project funded by the New Energy and Industrial Technology Development Organization (NEDO), the Innovative Structural Materials Association (ISMA) is developing a dedicated, compact electron-accelerator based neutron source at the National Institute of Advanced Industrial Science and Technology (AIST) in Tsukuba, Japan, for the characterization of structural materials. The accelerator is designed to have a maximum electron beam power of 10 kW (~36 MeV and ~275 mA), which will be incident on a water-cooled Ta target. The electron beam will have a maximum pulse length of around 10 μs at a repetition rate of 100 Hz. Neutrons produced through photo-nuclear reactions will be cooled by a decoupled solid methane moderator. Using this pulsed, low-energy neutron beam we plan to perform various imaging spectroscopies of structural materials including Bragg-edge imaging. In this contribution we will describe the dedicated neutron source in more detail, with particular emphasis on the electron accelerator. PB - JACoW Publishing CP - Geneva, Switzerland ER -
