Description

We review the small-angle neutron scattering (SANS) instruments, prepared at JRR-3, Tokai, Japan. Conventional pin-hole type SANS instruments (SANS-J-II and SANS-U) were recently reinforced by using focusing lens in order to detect ultra-small-angle neutron scattering (USANS) appearing at q=10-4Å-1, where q is a magnitude of scattering vector. The double crystal (Bonse-Hart) method is available at PNO instrument which is able to reach to the q-region of q=10-5Å-1. mfSANS instrument was designed to reduce its dimension using a focusing method Dynamical nuclear polarization (DNP) analysis is available at SANS-J-II, in order to perform contrast variation experiments.
