A microfocus beamline has been installed at an ESRF undulator. The applications of this beamline will be mainly in diffraction and diffuse scattering. An ellipsoidal mirror has been commissioned which results in a flux of 2×1011 Ph/s in a 10 μm (circular) collimated beam at 13 keV at a bandwidth of about 3 eV. Further tests on capillary optics and Bragg–Fresnel optics have been done.
