Dear Davide, The polarization factor depends on the incident X-rays not on the type of detector. If your radiation comes from a sealed tube or rotating anode source without monochromator there is no polarization of light and the factor is 0.5, the use of a filter does not change the polarization state. If you have an incident beam monochromator it depends on the material of the monochromator (or better on the diffraction angle). If you are using synchrotron radiation you will need something in the range 0.95 to 1 depending on the optics of the beamline. I hope this helps, Leo
