Hi Shay Not only specimen displacement, but also line broadening and relative intensities. They will all depend on the layer thickness. I don't know how well it would work, especially as WC is quite a heavy absorber, but in principle, it could. You could also try fixed incident been geometry

  Dear Pr. Francois GOUTENOIRE, In case of kapton tape there is a chance of getting diffraction peak at low angle, I prefer to use magic scotch tape. Some times to avoid the background from this tape as well, I use small punch in the thick paper card and pack the material in that hole for

Tricks for transmission sample preparation between foils

Dear Rietveld users, We are currently using transmission flat sample on our diffractometer. To prepare the transmission flat sample we are using mylar 15microns or kapton. We put the sample between 2 mylar foils. I would like to know if there is some tricks in order to nicely put the powder

Dear Rietveld users, Following Pr. Francois Goutenoire's question, I would like to add another question: I wonder how do you deal with electrostatic powders sample preparation though in Reflection mode. Do you use Kapton/mylar tape or any solvent to disperse the powder? How does it affect the
