Figure 4
Sketch of the microdiffraction set-up on ID15. The vertical microfocusing was achieved by a bent Laue crystal. A Debye–Scherrer cone is shown. The varying width is due to the dispersion of the Laue monochromator. The beams indicated by long (short) dashes relate to low (high) energies. The parameters of the set-up are compiled in Table 2. Scintillation counters were employed and the scattering angle was measured by slit scans. The lateral and axial residual strain profiles were measured simultaneously using two detector/slit units. |
