| Popis: | A new scanning transmission X-ray microscope for the soft X-ray region is under construction at the BESSY II storage ring. The radiation from the undulator U-41 is monochromatized with a monochromator consisting of a plane mirror and a plane grating with varied line density. For a high resolution image, the zone plate is scanned with a piezoelectric flexure stage. The X-ray flux in the focal spot will be of the order of 10 9 photons=s. The sample is located in air. A pn-CCD detector is used to measure the transmitted intensity. # 2001 Elsevier Science B.V. All rights reserved. |
