Abstract
A transmission W/B(4)C multilayer has been designed and characterized which shows significant phase retardation up to a photon energy of 1 keV, when operated near the Bragg condition. This allows, for the first time, the full polarization vector of soft x-radiation to be measured up to 1 keV in a self-calibrating method. Quantitative polarimetry is now possible across the 2p edges of all the transition metals.
摘要
已设计并表征了一种透射式W/B(4)C多层膜，当在布拉格条件附近运行时，该多层膜在高达1 keV的光子能量下表现出显著的相位延迟。这首次使得能够通过自校准方法测量高达1 keV的软X射线的完整偏振矢量。现在可以对所有过渡金属的2p边缘进行定量偏振测量。
