Application of Monolithic Capillary Half Focusing X-Ray Lens in Micro-EXAFS Analytical Technology

  • A monolithic capillary half focusing X-ray lens (MCHFXRL) is used to focus the synchrotron radiation. The magnitudes of the focal spot size and gain of the synchrotron radiation microbeam focused by the MCHFXRL are in the orders of 10μm and 103, respectively. In the energy range from 5.5 to 11.5keV, the focal spot size varies from 38 to 29μm; the transmission efficiency varies from 26.1% to 20.5%; the translation of the vertical position of the focal spot is 3μm; the change of the output focal distance is 155μm. On the basis of the investigation of the performances of the MCHFXRL, the application of the synchrotron radiation microbeam in micro-extended-X-ray-absorption-fine-structure (micro-EXAFS) analysis is studied.

Abstract: A monolithic capillary half focusing X-ray lens (MCHFXRL) is used to focus the synchrotron radiation. The magnitudes of the focal spot size and gain of the synchrotron radiation microbeam focused by the MCHFXRL are in the orders of 10μm and 103, respectively. In the energy range from 5.5 to 11.5keV, the focal spot size varies from 38 to 29μm; the transmission efficiency varies from 26.1% to 20.5%; the translation of the vertical position of the focal spot is 3μm; the change of the output focal distance is 155μm. On the basis of the investigation of the performances of the MCHFXRL, the application of the synchrotron radiation microbeam in micro-extended-X-ray-absorption-fine-structure (micro-EXAFS) analysis is studied.
