Infrared and X-ray Simultaneous Spectroscopy: A Novel Conceptual Beamline Design for Time Resolved Experiments

Many physical/chemical processes such as metal-insulator transitions or self-assembly phenomena involve correlated changes of electronic and atomic structure in a wide time range from microseconds to minutes. To investigate these dynamical processes we not only need a highly brilliance photon source in order to achieve high spatial and time resolution but new experimental methods have to be implemented. Here we present a new optical layout to perform simultaneous or concurrent Infrared and X-ray measurements. This approach may indeed return unique information such as the interplay between structural changes and chemical processes occurring in the investigated sample. A beamline combining two X-ray and IR beams may really take advantage of the unique synchrotron radiation properties: the high brilliance and the broad spectrum. In this contribution we will describe the conceptual layout and the expected performance of a complex system designed to collect IR and X-ray radiation from the same bending magnet on a third generation synchrotron radiation ring. If realized, this beamline will allow time resolved spectroscopy experiments offering new scientific opportunities in many frontier researches.
