      abstract     = {To study and control the incoherent inelastic background in
                      small-angle neutron scattering, which makes a significant
                      contribution to the detected scattering from hydrocarbon
                      systems, the KWS-2 small-angle neutron scattering

                      Science (JCNS) at Heinz-Maier Leibnitz Zentrum (MLZ),
                      Garching, Germany, was equipped with a secondary single-disc
                      chopper that is placed in front of the sample stage. This
                      makes it possible to record in time-of-flight mode the
                      scattered neutrons in the high-Q regime of the instrument
                      (i.e. short incoming wavelengths and detection distances)
                      and to discard the inelastic component from the measured
                      data. Examples of measurements on different materials
                      routinely used as standard samples, sample containers and
                      solvents in the experiments at KWS-2 are presented. When
                      only the elastic region of the spectrum is used in the
                      data-reduction procedure, a decrease of up to two times in
                      the incoherent background of the experimentally measured
                      scattering cross section may be obtained. The proof of
                      principle is demonstrated on a solution of bovine serum
                      albumin in D2O.},
