Abstract
In residual stress analysis (RSA) using energy dispersive (ED) diffraction care has to be
taken of the detector energy stability. For a given detector system it is demonstrated that the energy
position decreases significantly with dead time. Correction of the RSA data both in reflection and
scanning experiments allows a significant improvement in the reliability of RSA under different
conditions. Owing the small diffraction angles in ED experiments, the effect of adjustment errors in
reflection geometry is investigated revealing the need of a wide incoming beam combined with high
collimation of the secondary beam. The differences in the used absorber materials are shown in
respect of sample heating and beam widening due to diffuse scattering.
