Figure 13
(Normalized) angular-flux-density calculations for a wiggler field of 0.838 T and a (fundamental) X-ray energy of 12.66 keV plus harmonics in the (a) horizontal direction, (b) vertical direction. The vertical lines mark the edges of the X-ray beam as defined by the primary slits (solid lines for umbra and dashed lines for penumbra). The λ/2 and λ/6 harmonics are shown in grey because they relate to `forbidden' Bragg reflections (222 and 666, respectively). Further details are provided in the text. |
