      abstract     = {Following demand from the user community regarding the
                      possibility of improving the experimental resolution, the
                      dedicated high-intensity/extended Q-range SANS
                      diffractometer KWS-2 of the Jülich Centre for Neutron
                      Science at the Heinz Maier-Leibnitz Center in Garching was
                      equipped with a double-disc chopper with a variable opening
                      slit window and time-of-flight (TOF) data acquisition
                      option. The chopper used in concert with a dedicated
                      high-intensity velocity selector enables the tuning at will
                      of the wavelength resolution [Delta][lambda]/[lambda] within
                      a broad range, from $20\%$ (standard) down to $2\%,$ in a
                      convenient and safe manner following pre-planned or
                      spontaneous decisions during the experiment. The new working
                      mode is described in detail, and its efficiency is
                      demonstrated on several standard samples with known
                      properties and on a completely new crystallizable copolymer
                      system, which were investigated using both the conventional
                      (static) and TOF modes.},
