講演要旨
　　Although linear polarization analysis of the diffracted x-ray beam has become a routine method, especially in magnetic x-ray scattering, experimental conditions are still far away from perfection. This is even more true for the use of x-ray phase plates which may be employed to change the polarization of the incident beam. This talk will discuss recent developments on the technical, experimental and theoretical side, and it will outline the remaining challenges that need to be addressed in the near future. To show an example where x-ray diffraction with polarization analysis significantly improved our understanding of a sample, I will present our recent results on NpO₂.
