ABSTRACT
A compact hard X-ray split-and-delay line for studying ultrafast dynamics at free-electron laser sources is presented. The device is capable of splitting a single X-ray pulse into two fractions to introduce time delays from -5 to 815â
ps with femtosecond resolution. The split-and-delay line can operate in a wide and continuous energy range between 7 and 16â
keV. Compact dimensions of 60 × 60 × 30â
cm with a total weight of about 60â
kg make it portable and suitable for direct installation in an experimental hutch. The concept of the device is based on crystal diffraction. The piezo-driven stages utilized in the device give nanometre positioning accuracy. On-line monitoring systems based on X-ray cameras and intensity monitors are implemented to provide active alignment feedback. Performance estimates of the system are also presented.
