Figure 3
(a) Scheme showing that a shifted source is equivalent to a rotating CRL. Here, SRS is the synchrotron radiation source and D is the detector. A new optical axis makes an angle θ with the old axis. In reality xs ≪ z0. (b) The experimental rocking curve (markers) is taken from the work of Snigireva et al. (2004) and the theoretical rocking curve (solid line) is from this work. |
