Hiya all We are now the proud owners of a new Bruker D8 system with the twin Goebel mirror setup (Guinea Pigs R Us!). This has given me a few headaches with regard to modelling the instrumental broadening effects (not all of them solved) but that's another story. However, for Rietveld work with GSAS I am at a bit of a loss what value to use for the polarisation factor, as the diffracted beam mirror is sort of a monochromator but isn't in the conventional sense. Any suggestions or ideas would be most welcome.
