  In 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.
