Thanks for the interesting subject. It is really informing and very helpful
to improve instrumental resolution. P.S. Julian, ever tried additional SAXS
experiments changing several parameters to optimize your setup? Did you get

reducing tube power just reducing intensity which reduces your peak height
together with the background level. It won't help on the peak to background
ratio.
What you need to improve is the beam path. WhenI was checking the low angle
beam path, I measured the stage/goniometer dimensio
Shay,
Can we assume you are working with a reflection mode instrument?
You have two primary sources of background - the primary beam hitting the
detector directly, and x-rays scattering from the air rather than the sample.
The first of these you control with the divergence slits, but really sho
