Abstract
Neutron scattering method is essential in a study of internal structure and dynamics of material due to the exclusive nature of a neutron. However, owing to the extremely low intensity of the neutron beam compared with the synchrotron-radiation photoemission, it can be restrictedly applied. To improve this situation, we have been developing neutron refractive optics, such as a neutron lens and neutron prism. In this study, we have developed compound refravtive lens for cold neutrons.
