    • In order to achieve suitable positional resolution for an angular scan in Grazing Exit X-ray Fluorescence (GEXRF), the sample (2) should be irradiated with a small spot (14). Consequently, the fluorescent radiation yield is low so that the duration of a measurement is comparatively long. In order to mitigate this drawback, the invention proposes the use of an analyzing X-ray mirror (16) having a line focus (22) extending perpendicularly to the sample surface (4). The line focus (22) coincides with a line-shaped PSD (24), so that every position on the PSD corresponds to a given height on the mirror, which height itself corresponds to a given take-off angle of the fluorescent radiation relative to the sample surface. Excellent positional resolution and an attractive fluorescent radiation yield are obtained by irradiating the sample by means of a focused electron beam.
    • 为了在放牧出口X射线荧光(GEXRF)中实现角度扫描的适当位置分辨率,样品(2)应用小斑点(14)照射。 因此,荧光辐射产量低,使得测量的持续时间相对较长。 为了减轻这种缺点,本发明提出了使用具有垂直于样品表面(4)延伸的线对焦(22)的分析X射线镜(16)。 线对焦(22)与线形PSD(24)重合,使得PSD上的每个位置对应于反射镜上的给定高度,该高度本身对应于相对于荧光辐射的给定起飞角度 样品表面。 通过聚焦电子束照射样品,获得优异的位置分辨率和有吸引力的荧光辐射产率。
