PURPOSE: An ultra small angle neutron scattering device is provided to reduce time for measuring an ultra small angle neutron scattering because a plurality of detectors can be reduced. CONSTITUTION: An ultra small angle neutron scattering device comprises a first previous monochromator(110), a first monochromator(120), and a first analyzer set(200). The first previous monochromator is arranged in an optical path(101) of neutron lights, thereby Bragg-diffracting the neutron lights. The first monochromator receives the diffracted neutron lights, thereby Bragg-diffracting to a side of specimens(121,131). The first analyzer set analyze the neutron lights penetrated through the specimen and comprises first analyzers(210,220,230) and first detector banks(241,251,261). The first analyzers are placed in an opposite side of the first monochromator based on the specimens. The first detector banks respectively detect the neutron lights diffracted by the first analyzers. |
