Ultra small angle neutron scattering instrument at C1-3 in JRR-3M

An instrument for ultra small angle neutron scattering has been constructed at the beam line C1-3 of JRR-3M. Performance tests show that the instrument fulfills its function within the q range of 10 −5 –10 −2 A −1 at temperatures ranging at least from −20 to 100°C.
