First Light at IRIXS
On March 28, 2017, we saw "first light" at our new IRIXS spectrometer at the PETRA-III synchrotron in Hamburg. IRIXS stands for "Intermediate-energy Resonant Inelastic X-ray Scattering", a method that will allow energy- and momentum-resolved measurements of electronic modes in quantum materials with 4d valence electrons. The construction of the unique instrument is made possible by an Advanced Grant from the European Research Council. The photo shows Hlynur Gretarsson sharing a drink to celebrate this event with Markus Tischer, whose group designed the undulators that supply photons to the spectrometer.
