| Research Abstract |
A meter-length flexible hollow glass fiber with 20 micron-bore and 1.5 mm-cladding diameters has been examined to transport a synchrotron X-ray beam for controlling the trajectory. The large cladding diameter keeps the moderate curvature to satisfy the shallow glancing angle of total reflection. The observed transmission efficiency was more than 20 % at 12.4 keV. As a demonstration, we performed the wide-area scan of a synchrotron radiation beam to identify the elements for a fixed metal film through its absorption spectra. The result obtained at the project suggests that the optics is applicable to control an arrival time of X-ray pulses toward future X-ray pump-probe experiments.
