X-ray based methodology

Developing innovative instruments has always expanded our knowledge-horizon; all four Nobel prizes in science awarded to Uppsala University are closely related to instrument development. The instruments we develop today are aimed at providing even deeper insights into fundamental processes in matter by understanding the electronic structure on the atomic length and time scale.

List of people

One such recent development is the Uppsala coordination of the Uppsala Berlin joint Laboratory (UBjL) allowing for low dose photoemission on sensitive samples and the possibility to measure Coincidence ESCA.

Other areas of research include continuous improvement of our local laser source HELIOS for time-resolved photoemission, time-resolved MOKE and efficient bandmapping as well as making femtosecond-resolution RIXS at an XFEL possible.

At MAX IV in Lund we are leading the development of VERITAS beamline which will allow for very high resolution RIXS, and we are also heavily involved in the development of HIPPIE and SPECIES for high-pressure PES and for high-resolution soft X-ray RIXS.

Long term visions (>3 years) include the PETRA-III beamline, sub-meV with the FTS, exploring new opportunities with higher harmonic generation for time resolved core level spectroscopy, RIXS map spectrometer (further development of femtoseconds-resolution RIXS) and high kinetic energy ARToF.
