摘要：

At the Institute of Microstructure Technology (IMT) of the Karlsruhe Institute of Technology (KIT), a new type of refractive X-ray optics has been developed. Owing to its comparably easy fabrication method and the large aperture, the so-called Rolled X-ray Prism Lenses (RXPL) have the potential to be used with X-ray tubes in an industrial environment as a low-cost alternative to existing optics. The lens itself is built out of a micro-structured foil which is cut into shape and rolled around a winding core to form a refracting element for X-rays. The resulting refractive structure can be used as illumination optics. Diffractometry experiments with an NEST 1976a sample were performed and showed up to an 18-fold enhanced integrated intensity compared to that acquired with a steel tube collimator.
