Resolution
International Tables for Crystallography (2006). Vol. C, Section 2.5.1.3, p. 85 [ doi:10.1107/97809553602060000580 ]
Resolution 2.5.1.3. Resolution The momentum resolution in energy-dispersive diffraction is limited by the angular divergence of the incident and diffracted X-ray beams and by the energy resolution of the detector system. The observed profile is a convolution of the profile due to the angular divergence and the profile due ...
Incident X-ray beam
International Tables for Crystallography (2006). Vol. C, Section 2.5.1.2, p. 84 [ doi:10.1107/97809553602060000580 ]
Incident X-ray beam 2.5.1.2. Incident X-ray beam (a) Bremsstrahlung from an X-ray tube. Bremsstrahlung from an X-ray diffraction tube provides a useful continuous spectrum for XED in the photon-energy range 2-60keV. However, one has to avoid spectral regions close to the characteristic lines of the ...
