BL09 SPICA Special Environment Powder Diffractometer


Real-time observation of structure and its change of functional materials and non-equilibrium reaction in practical devices

Research ObjectivesFunctional materials (ionic conductor, dielectric and magnetic material, metal and metal ceramic composite and etc.) and practical devices (battery and etc.)
FeaturesThe atomic position of a light element such as hydrogen and lithium in a crystal structure can be determined precisely. An observation of structure changes in the practical device under an operative condition.
SPICA is a TOF-type special environment neutron diffractometer dedicated for the battery study using operando technique. This instruments could collect time-resolved diffraction data of active materials from an operating battery device. And these diffraction data can reveal what happens in the device under its operation. The neutron diffraction technique is suitable to understand the nature of functional materials and a relationship between their properties and their structures. SPICA incorporates diffraction technique with real-time observation to determine structure information.
