      abstract     = {The requirements of SANS instruments at the new high-flux
                      source ESS are discussed in context with detectors. Since
                      instrument fluxes are one order of magnitude (or more)
                      higher than at conventional reactors, new detector concepts
                      are essential. There, the new SoNDe concept ideally fills in
                      the gap.We will see that for most of the SANS measurements
                      SoNDe will ideally deal with the high intensities of SKADI.
                      The envisaged 20MHz count rate on 1m2 detector will serve
                      most of the experiments well. For instance single-shot
                      kinetic experiment need to deal with high intensities, since
                      the statistics must be collected in a single run.Apart from
                      the classical SANS requirements, we will discuss options for
                      high resolution. Liquid crystalline order demands for high
                      resolution in the classical SANS range, where neighbored
                      Bragg peaks need to be distingushed, where the peak width
                      will characterize the correlation length, and where the peak
                      width as a function of peak order will tell about the kind
                      of order (whether a paracrystal is obtained). At smaller
                      angles in the VSANS range, best resolution is required to
                      obtain smallest possible scattering angles with adequate
                      resolution. Both techniques would benefit from an
                      interpolation algorithm that could drive the resolution
                      higher by factors of 3 to 5 or even 10. Here, the Anger
                      camera principle would fill in the gap.While the classical
                      SANS experiments require highest count rates with well
                      separated dead times for each pixel that is usually obtained
                      by optically separating the light conduction for each pixel,
                      the high resolution Anger camera would need to spread light
                      cones over several pixels. While in the first case grooves
                      in the scintillation material would separate the light
                      conduction, they are not allowed in the second case. This
                      dilemma needs to be discussed and solved, where the emphasis
                      lies on the classical SANS applications, and eventually high
                      resolution options need to be seen as wishes for the
                      future.},
