A prototype hard x-ray K-B nanofocusing system at the 34-ID-E station of the APS. The beam can be rapidly switched between monochromatic and polychromatic modes.
Mirror figures measured by LTP. The rms deviation from the ideal ellipse can be even less over smaller regions of the mirror when ignoring the both ends. (a) Vertical mirror; (b) horizontal mirror.
Nanoprobe mirror tank. The white arrows indicate vertical and horizontal mirrors.
Patterned gold mask for precise and fast characterization of the beam profile. Either Au fluorescence or the reflected intensity by Au film can be collected. (a) A single Au stripe at glancing angle is equivalent to a wide pseudoslit or reflector. (b) Multiple nanoslits/reflectors were scanned across the beam at every along the beam axis.
Doubly focused monochromatic nanobeam at . The intensity profiles were obtained by scanning a Au nanoslit/reflector across the beam.
Vertical vibration spectrum measured by fluorescence correlation function spectroscopy. (a) The amplitude of vibration is on the order of at dominated frequency of . (b) and (c) Smaller focal spot sizes obtained in horizontal by turning off power to the most likely vibration sources.
Schematic of side-by-side Kirkpatrick-Baez mirrors. Both vertical and horizontal mirrors have identical figures and focal lengths.
Optical parameters of the K-B nanofocusing mirrors.
