Figure 4
Radial X-ray scattering background with air scattering subtracted measured on beamline 12-1 at SSRL. The water solvent ring at q = ∼1.8 Å−1 is evident in the filled chip (black data points). While the background scatter from the COC windows at q = ∼1.2 Å−1 is effectively controllable based on the film thickness (green versus red data points), it may exhibit minor fluctuations (green versus black data points) due to small variations in the film thickness across the film and among different chips. |
