The beamline ID24 is the ESRF XAS beamline for parallel detection of the whole spectral range. An optical concept has been selected which takes into account the specific properties of a third generation machine. The radiation is generated by an undulator. A coupling section contains two X-ray focusing mirrors in a modified Kirkpatrick-Baez geometry, with the second mirror strongly magnifying the horizontal divergence of the undulator beam. The spectrometer consists of a curved silicon crystal and a CCD camera lens-coupled to a scintillation screen. Users operation started in January 1996, taking advantage of a focal spot size of 25 μm and a time resolution up to 0.1 ms.
