The European Spallation Source (ESS), to be built in the south of Sweden, will use a 2.5 GeV superconducting linac to produce the world’s most powerful neutron source. The project is currently in a pre-construction phase, during which the linac design is being updated. This paper describes the current plans for beam diagnostics in terms of requirements, number and locations of different systems, and possible technical solutions.
