Description
The Beam Delivery System of ESS relies on a system of triangular wave raster scanning dipole magnets that paints each 2.86 ms beam pulse transversely across the spallation target. The system operates at tens of kiloherz and moves the beam centroid in a Lissajous-like displacement pattern with a rectangular outline. The beam scanner system is currently in production, with a two-magnet pre-series having undergone site acceptance testing at Aarhus University. The talk will highlight system design choices and performance results.
