本文报道了一种用于微米和亚微米空间分辨率的X射线吸收光谱、X射线荧光分析、X射线衍射和X射线小角散射测量的光束线的设计和建造。光束线的主要特点是在一个实验站中结合了所有这些方法。信号源将是BESSY 7-T波长移位器，它已经在运行中。这种具有连续光谱的波长移位器是进行这些实验的最佳光源。光束线的特殊光学元件选用玻璃毛细管和线性布拉格-菲涅耳透镜和双压片反射镜的组合。这条光束线将为BESSY用户提供使用微聚焦X射线束结合先进实验方法在同一样品上进行实验的可能性。
The design and construction of a beamline dedicated to X-ray absorption spectroscopy, X-ray fluorescence analysis, X-ray diffraction and X-ray small-angle scattering measurements with micron and submicron spatial resolution in the photon energy range of 1.9–30 keV are reported here. The main feature of the beamline is a combination of all these methods in one experimental station. The source will be a BESSY 7-T wavelength shifter, which is already in operation. Such a wavelength shifter with its continuous spectrum is an optimum source for these experiments. Glass capillaries and the combination of a linear Bragg–Fresnel lens and bimorph mirror were chosen as the special optical components in the beamline. This beamline will open for BESSY users the possibility to perform experiments on the same sample applying a microfocused X-ray beam in combination with advanced experimental methods.
