  The European Spallation Source is driven by a proton linear accelerator that will have an average beam power of 5 MW. The accelerator is pulsed at 14 Hz with a pulse length of 2.86 ms, and consists of both normal conduction and superconducting accelerating structures. The long pulse and the high goals of energy efficiency and availability create special challenges for the LLRF system.

  Sorting optical elements has significant potential during the construction of superconducting linacs like the ESS, in the same way that it has proved to be very effective in circular accelerators like RHIC and the LHC. In the linac domain, the elements of primary interest are cavities and cryomodules, instead of the magnets (of all sorts) that are routinely sorted in circular accelerators. Multiple cavities can be sorted to optimise individual cryomodules, and cryomodules can be sorted into optimised locations within the tunnel. Different sorting strategies are discussed and preliminarily evaluated in this paper. Central to the evaluation is the identification of goal (or penalty) functions that are maximised (or minimised), and which can be rapidly quantified by simulation. Also crucial is the availability of a modeling system that is realistic in its complex representation of the linac, and which can easily be modified and developed.
