To reduce the beam peak current density at the spallation target, the ESS HEBT will apply a fast transverse raster system consisting of 8 dithering magnet dipoles. The raster system sweeps the linac beamlet on the target surface and gives a rectangular intensity outline within a macropulse of 2.86 ms. The magnets are driven by triangular current waveforms of up to 40 kHz. The preliminary magnet design and power supply topology will be discussed.
