Figure 6
1D SAXS profiles calculated from the 2D detector images of silica NPs (100 nm) recorded with an open (red; simultaneous SAXS/SANS mode) and a closed (blue; standalone SAXS mode) neutron shutter for different neutron collimation lengths and X-ray sample-to-detector (SDxray) distances. Owing to the reduced neutron flux, the radiation background is insignificant on the X-ray detector for (a) a long collimation length, while for (b) intermediate and (c) short collimation lengths significant background radiation is observed for q > 0.31 nm−1. The intensity is plotted as an intensity normalized to the direct beam intensity with no background radiation subtraction for comparison purposes. |
