Figure 1
Angular dependence of the X-ray intensity transmitted by the diamond crystal close to Bragg conditions, measured for the four energy windows close to the Gd L3 edge, specified in Fig. 2. The angle Ψ was adjusted to obtain optimum non-dispersivity conditions: Bragg conditions are met at the same time in the four energy regions. The transmitted intensity is normalized to unity before the Bragg angle and it is artificially shifted vertically for three of the four energy regions. |
