Simulated X-ray spectra from two typical APS undulator sources, through a 1 mm × 1 mm pinhole located at 35 m away from the source. U18Gap10.5: undulator with a period of 18 mm and a gap of 10.5 mm; U33Gap25: undulator with a period of 33 mm and a gap of 10.5 mm. The electron energy is 7 GeV and the current is 100 mA. The spectral flux is normalized by the peak value. |
