“…Therefore, GISANS experiments are commonly conducted using SANS instruments rather than instruments that have been optimized for neutron reflectivity. 14,15,[35][36][37] Beam guides in the collimation section of the apparatus are detrimental because they reduce the resolution.…”

“…However, the number of reported GISANS experiments is still very limited compared with GISAXS, possibly because of continued restrictions on performing GISANS experiments compared with numerous GISAXS experiments at synchrotron radiation facilities. An interesting variation on the typical GISANS technique, known as time-of-flight GISANS (short TOF-GISANS), 30,35,39 has recently been developed. TOF-GISANS has no well-established counterpart in the X-ray field to date because of the inherent problems with radiation damage in using X-rays.…”

The enhancement of surface sensitivity by grazing incidence geometry facilitates the investigation of nanostructures in thin films and at surfaces. The technique provides information about the surface roughness, lateral correlations, sizes and shapes of objects (such as, nanoparticles and nanostructures) positioned on top of the surface or in a region near the surface. Grazing incidence small-angle neutron scattering (GISANS) overcomes the limitations of conventional small-angle neutron scattering for extremely small sample volumes in the thin-film geometry. Although real space analysis techniques, such as atomic force microscopy, provide easy access to surface structures, reciprocal space analysis techniques, such as GISANS, provide several advantages: (i) average statistical information over the large illuminated sample surface can be detected and (ii) buried lateral structures can be probed without damage, using the variable-probed depth as a function of the incident angle. To illustrate the potential applications and challenges of GISANS, several different examples of thin nanostructured polymer films are reviewed. Nanostructures in triblock copolymer thin films are studied in the bulk as well as at the polymer-air and the silicon-polymer interface. Confined nanostructures in a dewetted diblock copolymer film are also discussed in terms of contrast and experimental settings.

“…SANS based on time-of-flight (TOF) technology [9] has been developed in spallation neutron sources [10][11][12] . In addition, time-of-flight grazing incidence small-angle neutron scattering (TOF-GISANS) can be performed with such an instrument, which makes it highly promising for various future applications [13][14] . The highly quality of the data is the key to obtain accurate results.…”

Abstract:Small-angle neutron scattering (SANS) is an experimental technique to detect material structures in the nanometer to micrometer range. The solution of the structural model constructed from SANS strongly depends on the accuracy of the reduced data. The time-offlight (TOF) SANS data are dependent on the wavelength of the pulsed neutron source.Therefore, data reduction must be handled very carefully to transform measured neutron events into neutron scattering intensity. In this study, reduction algorithms for TOF SANS data are developed and optimized using simulated data from a virtual neutron experiment. Each possible effect on the measured data is studied systematically, and suitable corrections are performed to obtain high-quality data. This work will facilitate scientific research and the instrument design at China Spallation Neutron Source.
