      abstract     = {AbstractIn any neutron scattering experiment the
                      measurement of the position of the scattered neutrons and
                      their respective velocities is necessary. In order to do so,
                      a position sensitive detector as well as a way to determine
                      the velocities is needed. Measuring the velocities can
                      either be done by using only a single wavelength and
                      therefore velocity or by creating pulses, where the start
                      and end time of each pulse is known and registering the time
                      of arrival at the detector, which is the case we want to
                      consider here. This pulse shaping process in neutron
                      scattering instruments is usually done by using a
                      configuration of several choppers. This set of choppers is
                      then used to define both the beginning and the end of the
                      pulse. Additionally there is of course also a selection in
                      phase space determining the final resolution that can be
                      achieved by the instrument. Taking into account the special
                      requirements of a specific instrument, here a small-angle
                      neutron scattering instrument, creates an additional set of
                      restrictions that have to be taken into account. In this
                      manuscript a chopper configuration for two possible
                      settings, namely a maximum flux and a high-resolution mode
                      will be presented.Keywords SANS; Chopper; Time-of-flight;
