The FXE instrument will enable ultrafast pump–probe experiments on ultrafast timescales—below 100 femtoseconds—for a broad scientific user community.
The instrument comprises two independent secondary X-ray emission spectrometers next to a 1-Mpx detector for scattering studies. Its main research is devoted to dynamic studies of chemical and biochemical reactions in liquids next to different solid-state applications. With a powerful laser as pump source, it will permit studies with femtosecond time resolution exploiting different observables via a suite of hard X-ray tools (which may be further expanded over time):
The FXE scientific instrument will serve a broad scientific community and will embrace several fields of ultrafast X-ray science and their applications. State-of-the-art femtosecond instrumentation and techniques, both for X-rays and optical lasers, will deliver new information about geometric and electronic structures serving applications in many fields, and particular in the areas of
Operation of the FXE instrument is planned to start in 2017. A more detailed description of the science case of FXE can be found in the FXE TDR and CDR.
The main specifications and beam parameters of FXE are summarized in table 1 below. Further technical details about the available equipment at FXE is available here and in the TDR and CDR or by contacting the FXE group.
