The current performance of a 10‐m grazing incidence monochromator (GIM) is described. A resolution of 51, 95, and 220 meV (FWHM) has been achieved at 287, 401, and 867 eV, respectively, inferred from the linewidths for the K‐shell resonances of gaseous CO, N2, and Ne. A photon flux of ≂1012 photons/s is obtainable at the first harmonic of undulator radiation with a 1200‐l /mm grating and 50‐μm slit openings, which correspond to Δλ=0.04 A.
