Dear Davide,
the primary purpose of Soller slits in Bragg-Brentano geometry is to
reduce the axial divergence. Thus, a removal of the primary Soller
slit will cause
a) strong asymmetry of the low angle diffraction peaks
b) maybe axial beam overflow of the sample, resulting in "strange
background" bumps or diffraction peaks from the sample holder materials
a) is not critical, provided that your software is able to fit such
gemetrical profile abberation correctly, or if you do not care about
peaks say below 20 °2theta
b) is always critical, as stupid background or additional "non sample"
peaks are hard to describe.
My recommendation: Have a look on a fluorescent screen at the sample
position, to see if axial beam overflow exists. If not possible, it is
always recommended not to remove the primary beam Soller collimator.
Greetings
Reinhard
Zitat von davide.lev...@gmail.com:
Dear All,
I would like to know how the primary Soller Slits influence the
quality of the diffraction pattern, as from some test I did, I don't
see major differences in the peak shape. The use of these slits, on
the other hand, strongly cut the peak intensities.
Do you have any strong argument to use the primary Soller Slit for
qualitative and qualitative analysis?
Thank for your answer
Davide
