Abstract
The Gottingen transmission X-ray microscope at the low emittance electron s torage ring BESSY II uses the concept of dynamical aperture synthesis (Reyn olds, DeVelis, Parrent. Thomson (Eds.), The New Physical Optics Notebook, S PIE, 1990, pp. 536-548) for the object illumination. The concept is well su ited as a condenser, as it can match any required numerical aperture of the TXM objective. Furthermore, a novel off-axis transmission zone-plate monoc hromator is included. which can generate a monochromaticity of several thou sand in the object illumination. (C) 2001 Elsevier Science B.V.
