The European Spallation Source (ESS) will apply a fast beam scanning system to redistribute the proton beam transversely across the spallation target surface. The system operates at sweep frequencies of tens of kHz and efficiently evens out the time-averaged beam intensity within a nominal beam footprint, thus reducing the level of beam-induced material damage. A modular design approach divides the raster action in each direction across 4 independent magnet-supply systems to distribute the magnetic load, ease the peak output power per modulator, and in general reduce the impact of single points of failure. The state of the magnet design and power supply topology will be discussed.
