The use of an X-ray waveguide for scattering and diffraction experiments at an ESRF undulator is discussed. A maximum flux of 8 × 109photons s−1 at λ = 0.083nm was obtained with a multilayer monochromator. The combination of an Si (111) monochromator and ellipsoidal mirror resulted in a flux of 1 × 109photons s−1 in a 0.15 × 30 μm2 beam.
