Research

In a pump-probe approach, photo-induced structure changes in the femtosecond time domain are studied by diffracting ultrashort hard X-ray pulses from the excited sample. Both changes of atomic arrangements, i.e. lattice geometries, and of electronic charge density are addressed. The measurement of transient electron density maps has been pioneered by MBI and requires the simultaneous detection of many diffraction peaks. Femtosecond powder diffraction and the rotation method for single crystals have been implemented to fulfill this requirement.
