The orbit corrector magnets of the PETRA IV will be excited at elevated frequencies. This causes eddy-current effects in the magnet’s yoke and in the beam pipe. The eddy currents may deteriorate the aperture field. Moreover, they cause losses, which need to be cooled away. Accurate predictions thereof are necessary already during early design stages. In this student project, 2D and 3D finite-element magnet models will be set up. Appropriate model parts for the laminated yoke parts, the windings and the thin beam pipe will be inserted. They should allow to accurately simulate the particular eddy-current effects in these parts. A parameter study of the eddy-current effects for different design choices will be carried out.
