A tunable monochromatic X-ray source operating in the 1-20 keV energy range is described. An X-ray tube provides initial photons. A dispersive crystal performs the energy selection, according to Bragg's law. An X-ray detector is connected to the monochromator fixed exit. This setup can be used for metrological studies. A first application consists in measuring attenuation coefficients in the 4-10 keV energy range. Results for aluminum and copper are given, with average relative uncertainties (1sigma) of 1% and 3% respectively.
描述了一种在1 - 20 keV能量范围内工作的可调谐单色X射线源。一个X射线管提供初始光子。一块色散晶体根据布拉格定律进行能量选择。一个X射线探测器连接到单色仪的固定出口。该装置可用于计量学研究。第一个应用是测量4 - 10 keV能量范围内的衰减系数。给出了铝和铜的测量结果，平均相对不确定度（1σ）分别为1%和3%。
