Figure 2
Ray-tracing simulations for RP = 500 mm, r = 50 mm, θB = 75° (central beam) for the Si(440) reflection. The images show the crystal surface. The colours indicate the reflected energies. The asymmetry angles are 0°, 7.5° and 15° from left to right. The deviations (ΔE) are given in the colourbar in electronvolts. |
