✦ Synopsis

Neutron resonance spin echo (NRSE) enables us to measure neutron quasielastic scattering with high energy resolution. Its energy resolution is limited by neutron beam divergence. This divergent effect can be corrected by installing guide field between pair of resonance spin flippers. In this paper, we propose a beam divergence correction coil for NRSE spectrometer and evaluate its efficiency by numerical simulations.
