Photoemission (PES) has the ability to detect very small features in the band structure crucial for understanding the function of e.g. superconductivity, where it is of utter importance to determine the gap symmetry and positions of the nodes. This is illustrated by a study of the KFe2As2 iron-pniptide superconductor presented by K. Okazaki et al. in Science 337 (2012) 131. The data is recorded using a state of the art setup at Professor Shin’s lab at the Institute of Solid State Physics, University of Tokyo, including a Scienta Omicron R8000 hemispherical analyser, an upright helium-impounding cryostat and a laser system. This setup holds the world record in instrumental resolution of 70 μeV.
