Figure 3
Trigonometric functions related to the variation of: the Bragg angle θB with respect to energy E, as η0; and the gap g with respect to θB and E, as η1 and η2 (shown in absolute values for readability in the logarithmic scale), respectively. They follow (11), (12) and (13) for the DCM geometry of Fig. 1, including representative miscut manufacturing limitations, i.e. crystals with small asymmetric cut angles α. The HD-DCM angular limits are represented by the vertical dash-dotted lines at 3° and 60°. |
