The soft X‐ray spectroscopy beamline installed at a bending‐magnet source at the LNLS is described. The optics are designed to cover energies from 800 to 4000 eV with good efficiency. The focusing element is a gold‐coated toroidal mirror with an angle of incidence of 17 mrad. The UHV double‐crystal monochromator has three pairs of crystals, Si (111), InSb (111) and beryl (101¯0), that can be selected by a sliding movement. The UHV workstation is equipped with an ion gun, an electron gun, an electron analyser, LEED optics, an open channeltron and a photodiode array. This beamline is intended for photoemission, photoabsorption, reflectivity and dichroism experiments.
