Fundamental Physics using Neutron Optics

冷中子束流线BL05是在J-PARC建造的。利用我们的中子光学器件提供的高质量光束，开始了包括中子寿命精确测量在内的各种实验。这些设备的发展，例如，超冷中子的时空聚焦，使我们能够对超出标准模型的物理进行极高精度的测量。在材料科学方面，我们还开发了一些新的中子谱仪，包括聚焦VCN-SANS和共振NSE。

Cold neutron beam line BL05 was constructed at J-PARC. Various experiments including precision measurement of neutron lifetime was started with the high quality beam, which is provided by using our neutron optical devices. Developments of the devices, for example, space-time focusing of ultra-cold neutrons, enables us to perform extremely high precision measurement for physics beyond the standard model. For material science, we also developed some new neutron spectrometers including focusing VCN-SANS and resonance NSE.
