摘要：

The parameters of two elliptical poly-capillary lenses and one mono-capillary parabolic lens were characterized at the optical test bench of the BM05 ESRF beamline and at the BESSY mu Focus beamline. The poly-capillary lenses with an input aperture of circle divide 5-6 mm have shown a focal spot size (FWHM) on the order of 6-20 mu m with a gain factor of about 600-700 in a wide energy range. For the first time the parabolic mono-capillary lens has shown a focal spot size of < 2 mu m in the energy range of 10-15 keV. The gain factor reached 980. (C) 2008 Elsevier B.V.
