QENS focusses on the discussion and exchange of scientific ideas related to the investigation of atomic and molecular motions, while WINS deals with instrumental aspects of quasielastic and inelastic neutron scattering techniques. Though originally QENS and WINS were held independent of each other, the added value of their joint celebration was acknowledged in 2012, and continues today, since it enhances their scope and impact on the scientific community related with the quasielastic and inelastic neutron scattering techniques.
