Development of a single-shot CCD-based data acquisition system for time-resolved X-ray photoelectron spectroscopy at an X-ray free-electron laser facility

A single-shot CCD-based data acquisition system for time-resolved photoelectron spectroscopy using an X-ray free-electron laser has been developed. The basic performance of the system is demonstrated using XFEL-induced and synchrotron-radiation-induced Ti 1s core-level spectroscopy.

Polarization control of an X-ray free-electron laser with a diamond phase retarder

Circularly polarized X-ray free-electron laser beams have been generated at 11.56 keV, using a diamond crystal phase retarder at SACLA.
