摘要
The concept of a concave aluminium wedge-shaped absorber for hard X-ray synchrotron beamlines is presented. Unlike the commonly used absorber types (fixed-thickness absorber sheets or binary exchangers of individual fixed absorbers), this concept allows a compact system, controlled with a single linear positioner, and provides a wide attenuation range as well as a precise tunability over a large energy range. Data were recorded at the Nanofocus Endstation of the MINAXS beamline, PETRA III, Hamburg, Germany.
