title: A single W/B4C transmission multilayer for polarization analysis of soft x-rays up to 1keV.
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.
