Microprobe Endstation at SXRMB of Canadian Light Source: Introduction and Applications

Mapping of chemical element's distribution and Microprobe XAFS are the popular method to meet fundamental researches and industrial applications. Kirkpatrick-Baez (K-B) mirrors are normally utilized to realize the micro-focusing, commonly for energies above 4000 eV. At SXRMB, the microprobe station was designed to operate under vacuum, with a focus on applications in the challenging medium-energy region (2-4 keV). It uses a bending magnet source, covers an energy range of 1.7 -10.0 keV and uses a pair of K-B mirrors, focusing the collimated beam to a spot size of 10 m 10 m with 10 8 -10 9 photons/100mA/Sec flux [1]. A high resolution and large area CCD camera is equipped to obtain optical image of sample. A 4-element Si drift detector is used for mapping in fluorescence mode and TEY mapping is also possible.
