State‐of‐the‐art Experiments at the ESRF Magnetic Scattering Beamline

The ID20 beamline of the European Synchrotron Radiation Facility is presented with its main present characteristics and future directions. A few side experimental techniques are also presented that have highlighted the versatility of the diffractometer and the high quality of the optics. Nearly 7 years of continuous operation have also demonstrated unavoidable limitations that the on‐going upgrading of the beamline aims to overcome. The main features of this and related projects are described.
