      abstract     = {Grazing Incidence Neutron Spin Echo Spectroscopy (GINSES)
                      has recently been applied to measure the dynamics of
                      surfactant membranes close to a hydrophilic silicon wall.
                      The scattering depth of the evanescent wave inside the
                      microemulsion depends strongly on the angle of incidence and
                      the wavelength. The inherently low scattering intensity of
                      GINSES measurements, however, requires the integration over
                      a rather broad wavelength band. In particular, at a pulsed
                      source the instrument operates with a broad wavelength band
                      covering all neutrons within one frame between two pulses.
                      In order to yield viable counting statistics it is highly
                      desirable to integrate data corresponding to significant
                      fractions of the wavelength band. Therefore, in a normal
                      reflectometry setup the penetration length would be smeared
                      and blur the depth dependence of the experimental results.
                      Here we describe a new method to strongly mitigate this
                      effect and show its application in a GINSES experiment at
                      the neutron spin echo instrument at the Spallation Neutron
                      Source (SNS). A prism in front of the sample was introduced
                      in order to adapt the angle of the incoming beam according
                      to the wavelength by this optical component. As an example
                      an experiment on a bicontinuous microemulsion using these
                      neutron optics is presented. (C) 2012 Elsevier B.V. All
