A new soft x-ray monochromator design, especially conceived for high brightness undulator radiation, is discussed. Its aim is to achieve a resolution limited only by grating figuring slope errors, together with a simple grating rotation scanning; thereby operating with fixed entrance and exit slits. Three cylindrical optical surfaces are employed between the slits, including two mirrors focusing in their sagittal planes, and a resolution λ/Δλ up to ≈14000 at the carbon K-edge is predicted. Its implementation for the planned Trieste synchrotron radiation facility is described in detail.
