Figure 1
Detector images for diffraction from proton-irradiated Fe at 77 K, near the (033) reflection, with data collection parameters given in Table 1. The bars below images indicate rescaling of the images to show weak features. Panel (a) shows the Bragg reflection at the Bragg energy. The circles indicate the same detector position on the other images, where an afterglow is visible (i.e. a detector artifact). Lines indicate Debye rings owing to crystal mosaicity. Arrows indicate diffuse scattering. (See Fig. 2 for the scattering geometry for these features.) |
