A new multipurpose end-station for electronic, geometrical and chemical characterisation has been built on the renewed SGM3 beamline at the synchrotron radiation source ASTRID2 in Aarhus (DK). The beamline covers photon energies from 14 to 150 eV. The system is particularly well suited for electronic structure studies along arbitrary direction in k||, Fermi surface mapping, bulk bands mapping and temperature dependent measurements.
The end-station allows ARPES multichannel detection with a combined energy resolution better than 7 meV and angular resolution better than 0.1∘ with a 4 degree of freedom manipulator at 200-1300 K, or 5 degree of freedom manipulator at 70-800 K, or 6 degree of freedom manipulator at 25-500 K; sample preparation (sputtering, annealing 180-2300 K, chemical treatment, cleaving); STM measurement; Auger spectroscopy and epitaxial/MBE growth of thin films followed by RHEED. The poster describes the light source and the many opportunities of the end-station.
