Abstract

Instrumentation for sub-millisecond time-resolved SANS measurements at the National Institute of Standards and Technology (NIST) is described and applied to the reorientation dynamics of elongated hematite nanoparticles. Instrumentation for time-resolved Small-Angle Neutron Scattering (SANS) measurements with sub-millisecond time resolution, based on Gӓhler's TISANE concept, is in operation at NIST's Center for Neutron Research (NCNR). This implementation of the technique includes novel electronics for synchronizing the neutron pulses from high-speed counter-rotating choppers with a periodic stimulus applied to a sample. Instrumentation details are described along with measurements demonstrating the utility of the technique for elucidating the reorientation dynamics of anisometric magnetic particles.
