100 ps time-resolved solution scattering utilizing a wide-bandwidth X-ray beam from multilayer optics

100 ps time‐resolved X‐ray solution‐scattering capabilities have been developed using multilayer optics at the beamline NW14A, Photon Factory Advanced Ring, KEK. X‐ray pulses with an energy bandwidth of ΔE/E = 1–5% are generated by reflecting X‐ray pulses (ΔE/E = 15%) through multilayer optics, made...

Zusammenfassung:	100 ps time‐resolved X‐ray solution‐scattering capabilities have been developed using multilayer optics at the beamline NW14A, Photon Factory Advanced Ring, KEK. X‐ray pulses with an energy bandwidth of ΔE/E = 1–5% are generated by reflecting X‐ray pulses (ΔE/E = 15%) through multilayer optics, made of W/B4C or depth‐graded Ru/C on silicon substrate. This tailor‐made wide‐bandwidth X‐ray pulse provides high‐quality solution‐scattering data for obtaining photo‐induced molecular reaction dynamics. The time‐resolved solution scattering of CH2I2 in methanol is demonstrated as a typical example.
