(a) Power density of the damping wiggler source (DW100) at 28 m from the source, calculated using SRW (Chubar, 2001). The gray color scale represents the power density, ranging from zero (white) to the on-axis power density of 72 W mm−2 (black). The white box denotes the fixed mask aperture of 1.1 mrad × 0.1 mrad. (b) Power spectrum within the fixed aperture of the source (solid line), the beam after 2 mm of diamond (dashed line), and the beam after 2 mm of diamond and 4.8 mm of SiC (dotted line) or 8 mm of silicon carbide (dash-dotted line). |
