Fixed Flat Plate Geometry and PSDs
----------------------------------
We are currently using an Enraf Nonius FR590 with an
Inel CPS 120 positiion sensitive detectorand fisxed flat plate
geometry to carry out X-ray powder diffraction and subsequently
Rietveld analysis on mixtures of apatites.
We have been using DBWS and GSAS Rietveld packages with
Bragg-Brentano geometry as our nearest model to the fixed flat
plate geometry. This is of course inappropriate for detailed work
as the absorption correction is very different as are the sample
displacement calculations etc. We would like to hear from anyone
who knows of a reliable Rietveld package which treats the fixed
flat plate geometry correctly.
We would also like to communicate with anyone using a
diffractometer with a PSD (particularly with INEL CPS 120
detectors) so that we could exchange ideas and information.
Yours
Sincerely
Rory. M. Wilson
