Apparatus for Small-Angle Neutron Scattering and Rheological Measurements under Sheared Conditions

Abstract

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 JAERI Tokai, Japan.
