Petra III will be the most brilliant 3rd generation synchrotron facility in the
world when starting operation in 2009. In one of the long straight sections, a 10m long undulator will be installed. This device is dedicated to experiments requiring a high incident flux and a small focus. One of the instruments at this beamline will be dedicated to inelastic x-ray scattering for the study of electronic excitations with total energy resolutions of 50meV and 500meV, respectively. The size of the beam in normal operation will be 150 x 50µm2, and 1µm2 with additional focussing by KB-mirrors.
