We report on details of an apparatus constructed for the simultaneous small angle neutron scattering and rheological measurements under various sheared conditions. In addition to studies under steady (shear rate range; order of 10-3 - 103 sec-1) and oscillatory (frequency range; order of 10-3 - 102 rad/sec) shear flows, other tests such as creep, stress relaxation, etc. can be performed for a wide variety of complex fluids. Moreover, because of its design, the apparatus itself has flexibility for further modification. It is now open to users as a permanent equipment of SANS-U spectrometer of Neutron Scattering Laboratory, ISSP, The University of Tokyo, at JAERITokai, Japan.
