The SGM4 beamline on ASTRID2
The AU-SGM4 beamline, dedicated to nano- and micro-focussed Angle-Resolved Photoemission Spectroscopy (nanoARPES and microARPES) experiments, was commissioned in 2022 to run in parallel to the existing SGM3 ARPES beamline, with the U55 undulator switching between the SGM3 and SGM4 beamlines depending upon the experiment.
The main purpose of the SGM4 beamline is for experiments measuring the electronic structure of quantum materials where a small beam spot is necessary to collect ARPES spectra of single domains, surface terminations and electronic phases, as well as 2D materials and their heterostructures and operational devices incorporating quantum materials (in operando nanoARPES). Typically operating at photon energies of 12-150 eV, the nanoARPES measurements are optimised for high flux over the full energy range while maintaining the small ~4 µm beam spot.
