Novel multiple-beam very small angle neutron scattering (VSANS) using a conventional SANS instrument

A novel technique is described to produce multiple neutron beams, which focus at the sample, and allow very small angle neutron scattering (VSANS) measurements to be made using a conventional small-angle neutron scattering (SANS) instrument. This extends the range of material length scales able to be studied to greater than 1 µm (and scattering vectors down to 10⁻⁴ Å⁻¹), almost one order of magnitude greater than that of a conventional SANS instrument.
