A new spectroscopic facility, consisting of a planar/helical undulator and a 6.65 m off‐plane Eagle monochromator, has been designed. It can supply high‐flux and high‐resolution photons with `exotic' polarization in the 5–40 eV energy range. The astigmatism can be compromised by horizontally focusing the incident radiation on the grating. The rotation of a post‐focusing toroidal mirror compensates for the deviation of the exit beam caused by the grating translation. The whole system will be installed at beamline SU5 of SUPER‐ACO (0.8 GeV) at the beginning of 1998. With a 4300 grooves mm −1 grating, a resolving power of around 10 5 is expected at 20 eV.
