What is it about?
Incoherent scattering (Compton and fluorescence) cannot be avoided in XPDF (X-ray Pair Distribution Function) measurements using an area detector. This article explores the effects of random noises from Compton and fluorescence on local structural information of disordered materials.

Why is it important?
Our studies provide a deeper understanding of the effects of incoherent scattering on XPDF analysis and propose an experimental strategy for high-quality XPDF data collection using an area detector.
Perspectives
Studying local structures using the XPDF method concerns collecting weak diffuse scattering, which is vulnerable to random noise. Thus, it is always curious to me how incoherent scattering interferes with a weak diffuse scattering in the measurement using an area detector. I find the result very pleasing that local structural information can be recovered with high enough counts.
