N2 - A cost-effective chopper layout for the chopper cascade of MIRACLES, the time-of-flight backscattering spectrometer of the European Spallation Source is described. The main driving force is the capability to display a versatile and flexible selection of configuration modes, taking advantage of the long ESS pulse and tailoring the instrument resolution ad hoc, and covering a broad range of observation times from 10 ps to the ns. A key element for the design here presented is the feasibility to reach an energy resolution contribution from the incident neutron beam of ∼1.2 μeV, while keeping the same performance of MIRACLES conceptual design. The present optimized concept results in a well-balanced combination with the contribution from the secondary spectrometer time-of-flight energy resolution, yielding a total energy resolution of 2 μeV at best, and 2.5 μeV when the primary and secondary spectrometer contributions are matched.
