The Quantum Beam Science Center of Japan Atomic Energy Agency (JAEA) is promoting a wide variety of science and technology by multiplex and complementary use of various quantum beams from the JAEA-owned large-scale facilities and instruments. These are high-intensity and high-quality photons from J-KAREN laser facility in Kizu, synchrotron radiation from SPring-8 beam-line facilities in Harima, neutrons from JRR-3 research reactor and J-PARC/MLF spallation source in Tokai, electrons and ion beams from accelerator facilities in Takasaki. The research activities cover wide areas from basic and applied sciences to industrial applications relevant for environment and energy, materials, life science and biotechnology.
In this talk the R&D of the Quantum Beam Science Technologies at JAEA will be presented with an emphasis on materials exploration with neutrons and synchrotron x-rays. Discovery of NaCl-type lanthanum monodeuteride under high pressure by complementary use of synchrotron x-rays and neutrons, in-situ load experiment on residual stress in reinforced concrete using neutrons, utilization of polarized neutrons in magnetic materials imaging and spin contrast variation technique for soft matter will be reported.
