The RIXS (Resonant Inelastic X-ray Scattering) technique was pioneered already in the 1980’s, and since then it has provided a broad range of applications. It relies heavily on access to a high brilliance source of primary photons, and it is only recently that the full power of the method has been realised. The new synchrotrons offer the ability to monitor the process with a high level of control over energy and momentum and angular momentum transfer. It has been demonstrated that e.g., that fundamental excitations in correlated materials can be studied in detail, and that individual vibrational excitations in molecular systems can be resolved. It is obvious that the improved spectral quality will open the door to new classes of phenomena, and it is envisioned that e.g. local ultrafast electron-phonon interaction, which determines the properties of many materials, will be possible to investigate in detail.
The Veritas beamline is designed to fully exploit the extraordinary brilliance of the 3-GeV ring at MAX IV with the aim to further refine the RIXS method and to become a world-leading facility in this highly competitive field. It comprises a grating spectrometer, which covers the 275-1 500-eV energy range, i.e., the range where resonances of many important species, including carbon, nitrogen, and oxygen K, and the transition metal L resonances. To achieve high energy resolution the instrument is fairly large (a total length of approximately 10 m), and to achieve high momentum transfer resolution it can rotate 120 degrees in the horizontal plane.

MAX IV Highlights 2019

  2019 was a landmark year for MAX IV Laboratory. Continuing the long-standing tradition of delivering innovative technical instruments and capabilities for x-ray science to the research community since MAX-lab was inaugurated in 1987, MAX IV broke new ground by opening five new beamlines to users, and bringing three more into the commissioning phase for
