As we approach the temporary shutdown for the SLS 2.0 upgrade this autumn, PSI scientist Thorsten Schmitt looks back on 22 years of scientific excellence studying quantum materials using synchrotron radiation at the Swiss Light Source SLS. Here, Thorsten speaks about discovering a new quasiparticle called the orbiton. The SLS was instrumental in discoveries such as this, by enabling the resolution of resonant inelastic X-ray scattering to be pushed to new limits. Such insights into novel materials are important for understanding phenomena such as high temperature superconductivity. What science did the SLS make possible for you? Join us in honouring the past 22 years of scientific and technical excellence by sharing these with #ThankYouSLS!
