The designs utilise rotating crystal and Laue analyser optics respectively to energy analyse a pink synchrotron X-ray beam after reflection from a liquid surface. Some performance estimates are presented, along with results of a test experiment using a laboratory source and solid state detector.Keywords: Energy dispersive; Laue; Time resolved; X-ray reflectometer200110.1016/S0168-9002(01)00550-22015-12-12
