Description
The European Spallation Source (ESS) will apply a fast beam raster 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, thus reducing the level of beam-induced material damage and decreasing component cooling demands. Designed for a long-pulse spallation neutron facility, the ESS raster system will operate at only 5% duty cycle (covering the proton beam pulses) and provide a nominal beam footprint with a rectangular outline (matching the target and moderator geometry). Following a presentation of the ESS design, ideas of how the concept could be adapted to be more suitable for ADSRs will
be presented.
