Summary:The sensitivity of the spin-echo small-angle neutron scattering technique based on magnetic fields that increase linearly with time is analyzed depending on the scattering geometry and the detector apperture. The application of sectoral collimators for the selection of scattering neutron trajectories is substantiated with the aim of improving the resolution and the corresponding effect on the data acquisition time is estimated.
