An X-ray beamline for utilizing intense, high-energy undulator radiation
The design, development and performance of an X-ray beamline for utilizing intense, high-energy undulator radiation are presented. A double multilayer monochromator, consisting of 150 pairs of 3.33 nm periodic Cr/C multilayers, provides intense X-rays by extracting a 1% energy bandwidth from high-order harmonic undulator radiation. We experimentally confirmed a high flux of 3.4 × 10<sup>13</sup> (1.3 × 10<sup>11</sup>) photons s<sup>-1</sup> with a beam size of 0.7 (0.3) mm (vertical) × 2.9 (∼4) mm (horizontal) at an X-ray energy of 100 (267) keV with a 1.0% (1.2%) energy bandwidth. Excellent performance of the high-energy high-flux X-ray beam was proven by conducting high-speed imaging analysis.
