Table 1. Comparison of the used techniques for the investigation of the VL structure and IMS domain formation.
| Technique | Instrument | q-range sensitivity (Å−1) | d-range sensitivity (nm) | Spatial resolution (determined by) | Information about |
|---|---|---|---|---|---|
| SANS | SANS 1 | 2 × 10−2 to 1 × 10−3 | 30–600 | 3 mm diameter (aperture) | VL |
| VSANS | KWS 3 | 3 × 10−3 to 1 × 10−4 | 200–6,000 | 5 mm × 10 mm (aperture) | IMS domains |
| nGI (TI) | ICON | 2 × 10−1 to 3 × 10−3 | 3–200 | 0.5 mm (geom. blurring) | VL |
| nGI (DFI) | ICON | 6 × 10−3 to 1 × 10−5 | 100–60,000 | 0.5 mm (geom. blurring) | IMS domains |
DFI, dark-field images; nGI, neutron grating interferometry; SANS, small-angle neutron scattering; TI, transmission images; VSANS, very small-angle neutron scattering.
The q-range of the TI was calculated assuming that the scattering angle must be larger than the geometrical blurring caused by the high sample to detector distance (SDD) but smaller than the angular range which is covered by the detector.
