A first X-ray imaging microscopy test using the two types of “micro-capillary lens” (kind of the X-ray refractive lenses) has been done at the undulator and bending magnet radiation of SPring-8. One (lens No.1) contained bubbles in glue whereas the other (lens No.2) contained bubbles in glycerol. The lenses had the inner diameters of 0.2 mm and 0.8 mm, respectively. The tests were mainly done using the lens No.2 and the 17-18 keV X-rays. By taking the images of a gold mesh, the spherical aberrations and the field distortions were carefully examined. This lens is superior with a large aperture, 0.8 mm, and a small field distortion, e.g., less than 10 % inside the diameter of 300 μm. [ABSTRACT FROM AUTHOR] |
